Two in one NPK fertilizer granulator is widely used for the granulation of NPK fertilizer and organic fertilizer. Because of its high granulation rate, stable operation, strong and durable equipment, and long service life, it is the first choice of organic fertilizer production equipment by the majority of users. Its volume is larger than that of the disc granulator and its production capacity is stronger. During the installation, the following items should be paid attention to.
The two-in-one granulator with rotating agitator teeth shall be installed on the horizontal concrete foundation. For the sake of safety, the granulation equipment shall be further strengthened with anchor bolts. During the installation, the main engine body shall be kept vertical to the horizontal plane. After the installation, further inspection shall be carried out, including whether the bolts of each part have been fixed. If there is looseness, reinforcement shall be carried out in time to ensure that all parts are installed.
When the power supply of NPK fertilizer granulator is configured, it should be selected according to the power of the equipment itself. After checking and confirming that there is no problem, carry out no-load test run. The test run is normal and can be put into production.
When maintaining the two in one NPK fertilizer granulator, pay attention to the selection of lubricants, because good lubricants have a great impact on the life of the bearing, and the use of inferior lubricants is prohibited. Generally, the parts requiring sealing and oiling include rotating bearing, roller bearing, all gears, movable bearing and sliding plane. Regular and regular inspection shall be carried out. Once problems are found, maintenance shall be carried out in time. If there is abnormal sound during use, production shall be stopped immediately to avoid safety accidents.
Our company has developed and produced internal rotating gear granulator of 60, 80, 100 and other specifications, which can also be customized according to the fertilizer production line and user needs. The shell of pelletizer is made of thickened seamless steel pipe, which is durable and will never deform. In addition, the stable base design makes it run more smoothly.
There are disc granulator and rotary granulator earlier in fertilizer granulation equipment, but these can not meet customer requirements. Now NPK fertilizer granulator is widely used. It does not need to add any fillers and binders when granulating, which greatly improves the granulation rate.
The new NPK fertilizer granulator developed by our factory can be widely used for raw materials, such as chicken manure, pig manure, cow manure, straw, sludge, humic acid, peat, cake fertilizer, etc., and can also be used for some carbon black and mineral powder which are difficult to be granulated. Organic and inorganic NPK fertilizer granulators do not have high requirements for the fineness of raw materials. Generally, they can be granulated when the fineness reaches about 40 meshes. The moisture requirements of the raw materials are not high. The moisture of the raw materials can be granulated at 15-45. The size adjusts the moisture and greatly reduces the equipment investment.
The organic and inorganic fertilizer granulator is particularly suitable for granulating organic fertilizers and fermented fertilizers, adapting to various formulas. The compressive strength of organic fertilizer is higher than that of general fertilizer granulator. The fertilizer granulation process saves the drying process before granulation and reduces production costs.
Only when the organic fertilizer production equipment is well maintained can it develop its life to a large extent, and it is not so difficult to maintain. Pelletizer is the core of organic fertilizer equipment, more attention should be paid to daily maintenance. Before start-up and use, idle NPK fertilizer granulator for a while to check whether all parts work normally. Later maintenance operation is also very simple:
1. The wheel hoop is easy to loose, and it must be checked frequently.
2. Pay attention to whether all parts of the machine work normally.
3. Pay attention to check the wear degree of easily worn parts and replace the worn parts at any time.
4. For the underframe plane of the mobile device, dust and other materials shall be removed to prevent the mobile bearing from moving on the underframe when the machine encounters materials that cannot be broken, so as to cause serious accidents.
5. If the bearing oil temperature rises, stop the machine immediately to check the cause.
Organic fertilizer resources are rich and various, including not only manure, straw, green fertilizer, soil and miscellaneous fertilizer, but also cake fertilizer, sea fertilizer, biogas fertilizer, etc. The results showed that the organic-inorganic fertilizer combined application can promote soil nutrient recycling and reuse, increase crop yield, improve the quality of agricultural products, and accelerate the harmless and resource utilization of organic waste, which is the fundamental guarantee for the sustainable development of agriculture. The industrial fertilizer production line also processes organic fertilizer and NPK fertilizer in proportion. So how should organic and inorganic fertilizers be used together?
Apply less fertilizer frequently. The nitrate nitrogen and ammonium nitrogen in the compound fertilizer will absorb part of the heat during the dissolution process, which may affect the ground temperature and cause adverse effects on the growth of crop roots. However, the normal growth of crops still needs sufficient supply of nutrients. Therefore, when applying the compound fertilizer in winter, it is necessary to apply less frequently and try to do so in the morning when the weather is fine.
Inorganic fertilizer should be applied in combination with pure biological fertilizer (without nitrogen, phosphorus and potassium). Long-term single use of chemical fertilizers will gradually consume the organic matter in the soil, resulting in the reduction of the number of beneficial microorganisms in the soil, the reduction of enzyme content, and the destruction of colloids, resulting in soil compaction, acidification, and salinization. NPK fertilizer and organic bio-fertilizer can improve the soil, reunite the sand, loosen the clay, inhibit the pathogenic bacteria, restore the micro-ecological environment in the soil, enhance the soil permeability, and improve the ability of retaining water and fertilizer. The fertilizer plant uses a disc granulator to process organic and inorganic fertilizers in order to improve fertilizer efficiency.
Fertilizer should be applied pertinently. For vegetables such as leafy vegetables, because of their fast growth, high nitrogen demand and low phosphorus demand, the compound fertilizer with high nitrogen content and low phosphorus content should be selected for use; for fruits and melons, the demand for potassium is more in the fruiting period, and the demand for phosphorus is less, so the compound fertilizer with high potassium and low phosphorus can be selected; for the next vegetable seedling, the compound fertilizer with higher phosphorus content can be used as the base fertilizer because of the large demand for phosphorus in the seedling period, Some compound fertilizers with higher phosphorus content were applied after the slow seedling was planted.
The fertilizer granulator manufacturer suggests that the fertilizer should be applied in a scientific way. According to the above principles, the organic and inorganic fertilizers should be used together to improve the agricultural income.
Stirring drum granulator can not only granulate the organic matter after fermentation, but also granulate a variety of NPK fertilizers. It is an efficient multifunctional granulator. NPK fertilizer granulator adopts wet granulation in the process of fertilizer production, using water as the medium, not only the granulation speed is fast, the process efficiency is high, but also the strength of fertilizer particles is high.
NPK fertilizer granulator is the key equipment of wet granulation. It is used together with the dryer in the fertilizer production line to complete the wet granulation process of organic fertilizer. In the process of granulation, by adjusting the circumferential linear velocity and average residence time of the agitator, the granulation quality requirements of various organic fertilizer materials can be met. Compared with the traditional drum granulator, the process efficiency of the organic compound fertilizer granulator is significantly improved. If the size of the agitator is properly selected, such as radius 800-1000mm, the production capacity of the equipment can reach 8t/h or higher. The filling amount and residence time of organic fertilizer material in granulator are affected by the rotational speed of stirring gear shaft. When the yield of pelletizing fertilizer is constant, the filling amount and residence time decrease proportionally with the speed of the agitating gear shaft.
As a manufacturer of organic fertilizer production equipment, Zhengzhou Huaqiang provides a variety of fertilizer granulators and fertilizer production processes. In order to increase fertilizer efficiency and improve production efficiency, we continue to develop more efficient fertilizer granulation machine.
NPK fertilizer granulator has unique advantages and characteristics compared to general granulating equipment. The stirring tooth-drum granulator produces organic fertilizer with high spheroidization rate and good granule strength, and can achieve granulation purpose for a variety of raw materials such as crop straw, medicine residue, bacterial residue, animal feces and so on. The fertilizer production line equipment matched with the granulator includes pulverizer, mixer, belt conveyor, drying machine, cooler, screening machine, packaging machine, etc.
Extrusion force of double roller press granulator is an important parameter for safe and stable operation of granulator. The pressure of double roller granulator directly affects the extrusion effect and quality of fertilizer granulation process. Therefore, the pressure regulation of roller press granulator is an important control parameter in the granulation process. Proper pressure can increase the output of fertilizer granulation, reduce energy consumption and prolong the service life of granulator.
The granulation mode of roller granulator is different from that of drum granulator. If the pressure of roller granulator is too small, there will be more gaps between fertilizer particles, which can not meet the pressure required for material extrusion, and dense filter cake will not be formed, which will affect the effect. If the pressure is too high, it is easy to cause "re polymerization" phenomenon between the material particles, which makes the filter cake difficult to disperse and classify, and will aggravate the wear and damage of roller surface and bearing.
According to the operation current of the main motor, the particle size of the material, grindability and the looseness of the filter cake, we choose the appropriate pressure to adjust the pressure of the roller granulator. The higher the current of roller extrusion granulation equipment is, the more work is completed and the higher granulation capacity of fertilizer is.
When the particle size of the material is large and the abradability is poor, the higher pressure can be properly controlled. When the pressure increases, no matter whether the observed current increases or not, if not, the extrusion pressure of the system has reached the upper limit and the pressure is invalid, so it should be adjusted to the original set pressure.
In the granulation process of the organic fertilizer making machine, when adjusting the pressure of the granulator, it is necessary to check the hydraulic system, side baffles and roll gap of the roller granulator, and pay attention to whether the control parameters are within the design range. Only by properly adjusting the pressure of the roller press granulator can the granulation achieve the expected effect and improve the fertilizer production efficiency in the fertilizer granulation process.
Huaqiang factory's fertilizer equipment drum granulator solves the problem of wall sticking. The fertilizer drum steam granulation manufacturing process has large output flexibility. Rotary drum granulator is cylindrical and has good heat preservation effect. The steam is used to increase the temperature of the material during granulation to meet the liquid phase required for granulation, which can greatly reduce The water content of the material during granulation reduces the load of the dryer and increases the output of the whole machine.
The double roller granulator uses dry granulation, while the main working mode of drum granulator is wet granulation. After the basic fertilizer is humidified in the cylinder by a certain amount of water or steam or gas ammonia or phosphoric acid or nitrogen solution, the compound fertilizer production line of chemical reaction and heat supply or the cold granulation process with a small amount of water is added. Under the condition of temperature and humidity, with the help of the rotary movement of the cylinder, the material particles are squeezed and agglomerated into balls.
The drum granulator has a wide range of adaptability to the production of raw materials. It can be used in combination with low-solubility and high-solubility materials as required, and can also be used with some organic matter and medium and trace elements. In the organic fertilizer manufacturing process, the problem of wall sticking in the drum granulator is more serious, which directly affects the movement of the material, and affects the ball formation rate and the roundness of the granules. To solve this problem, we have developed a high lining on the inner wall of the granulator. The movable inner lining of molecular materials solves the problem of wall sticking of materials and plays a role of anti-corrosion and heat preservation.
The drum granulator is suitable for nitrogen, phosphorus and potassium nutrients, with flexible nutrient distribution ratio. It can process high nitrogen compound fertilizer, all kinds of special fertilizer, organic and inorganic compound fertilizer with more than 20% nitrogen element.
With the continuous improvement of the level of agricultural science and technology, the promotion of high-yield varieties, the improvement of land re cultivation index, and the vigorous development of economic crops, flowers and urban greening. The growth of crops and the ecological balance of nutrients in the soil are becoming more and more serious, and the phenomenon of crop sulfur deficiency is becoming more and more serious.
Sulfur-coated urea fertilizer has become a popular fertilizer product on the market. It is coated with a layer of sulfur and other trace elements on the outside of the urea through a coating machine, powdering machine, etc., so that the fertilizer nutrients are slowly released. It is different from the compound fertilizer rotary drum granulator processing technology.
One time application of sulfur coated urea fertilizer can meet the needs of various growth stages of crops. With the high cost and shortage of modern agricultural labor, the application of sulfur coated urea in some crops also shows its characteristics. For example, planting sugarcane, because the growth period of sugarcane is several months, it is not easy to carry out mechanized fertilization after sugarcane crown is closed. At the early stage of self growth, single fertilization can meet the needs of crops, which is welcomed by sugarcane farmers. Strawberries grown in plastic mulch are also easy to apply nitrogen fertilizer, so 70% of strawberry growers in California use sulfur coated waste.
We provide a complete set of sulfur coated urea fertilizer production line, as well as disk granulator, drum granulator, double roller granulator, coating machine, packaging machine and other fertilizer production equipment.
In order to process commercial organic fertilizer with animal manure, the equipment and early fermentation are the key to the production. In the early stage of fermentation, the C / N ratio, moisture and oxygen status of fermentation materials should be adjusted, the working conditions of microorganisms should be improved, and the fermentation time of organic materials should be shortened. In the later stage, the processing of organic fertilizer mainly focused on granulation.
Organic fertilizer granulating machine is a kind of molding machine which can make material into specific shape. There are many kinds of granulators, such as rotary drum granulator, new type organic fertilizer granulator, disc granulator, two in one NPK fertilizer granulator, flat die pellet mill, etc. According to the characteristics of production materials and the requirements of granulation, different granulating equipment can be selected.
The disc angle of the disc granulator adopts the whole arc structure, and the pelletizing plate is equipped with three discharge ports, which is convenient for intermittent production. The reducer and motor are driven by flexible belt, which can start smoothly and slow down the impact force of the disc granulator. The base design of the plate bottom is heavy, solid and thickened. It is strengthened by multiple radiation steel plates, which is durable and durable. It does not need to be fixed by anchor bolts and runs smoothly.
The two-in-one NPK fertilizer granulator uses the granule wet granulation method to pass a certain amount of water or steam to make the basic fertilizer fully chemically react after adjusting the humidity in the cylinder, under certain liquid phase conditions, with the help of the rotary motion of the cylinder In order to squeeze the material particles into a ball, we add the mechanical stirring force of the high-speed rotation of the roller tooth cutter and the resulting aerodynamic force on this basis, so that the fine powder material can be continuously mixed in the machine.
Before granulating, the flat die extrusion pellet mill must first use a semi-wet raw material pulverizer to pulverize the organic fertilizer raw materials, and use the cutting knife to granulate the raw materials into cylindrical bodies. For the entire organic fertilizer granulation equipment, we can provide you with a complete production line work plan. Help users choose suitable granulation equipment to meet production line requirements.
After arriving at the plant, the roller extrusion organic fertilizer granulator will be installed with the granulator as the main machine according to the number of units and the organic fertilizer manufacturing process flow chart to find out the elevation and horizontal position. There are corner holes in the frame, which can be installed on the concrete (the solid vibration is not large, and a very solid concrete foundation is not required).
Our double roller granulator has been debugged before delivery, but it still needs to be adjusted after trial.
(1) Adjustment of press roll clearance
In the fertilizer production line, it is sometimes necessary to increase the data output or data biting angle. In this case, the distance between the two compression shafts can be increased and the clearance between the drive shaft roller and the driven shaft can be increased.
The steps are as follows: stop the roller granulator, remove the frame above the two bearing blocks, adjust the adjusting plate between the two bearing blocks to the required thickness, prevent the roller collision between the two rollers, and maintain the minimum clearance of 0.3-1 mm.
(2) Ball and socket alignment adjustment
The ball and socket are formed by the pits on the surface of the main roller, so there are problems of axial alignment and circumferential alignment.
Axial alignment has been adjusted during installation. Generally speaking, there is little possibility of adjustment. When adjustment is needed, tighten or loosen the gland on both sides of the passive bearing seat, so as to push the displacement of the eccentric sleeve corresponding to the driving shaft roller.
Align the circumference. The steps for circumferential alignment are as follows: Loosen the 6 connecting bolts of the driven gear and the adjusting sleeve, so that the adjusting sleeve and the driven gear are slightly separated. Since one ball and socket adjustment is considered in the design, and two adjustment bolts are provided, the deviation can be adjusted no matter how large the deviation is. Because the ball socket of the double roller granulator is too small, the cardboard is placed between the two rollers during adjustment. After rolling, you can see whether the adjustment has achieved the purpose. After alignment, tighten 8 connecting bolts.
We provide NPK fertilizer granulator equipment, users can get professional engineer guidance after purchasing the equipment, we provide help in installation.
With the diversification of raw materials, organic fertilizer manufacturers are constantly developing new granulation equipment. In the production of ordinary organic fertilizer, there is a stirring tooth fertilizer granulator, which has high production efficiency and good product quality. In terms of organic-inorganic compound fertilizer, there is also a new NPK fertilizer granulator, which is improved on the basis of the agitating gear granulator, which solves the problem of material adhering to the wall and produces beautiful particles.

The wet granulator of organic fertilizer can realize the material selection. As long as the organic matter after effective fermentation can be granulated by the new granulator, which breaks the limitations and obstacles of the traditional process.
(2) The compressive strength of NPK fertilizer granulator is higher than that of disc granulator and rotary drum granulator. There is no need to stop the processing of raw materials, crushing and drilling before granulation, so it can directly realize batching processing and direct granulation. The granulation equipment is suitable for many kinds of organic fermentation products, such as livestock manure, grain straw, mushroom residue, sawdust, soy sauce residue and so on.
(3) This kind of drum granulator not only saves a small amount of electric power investment, but also improves the production efficiency of organic fertilizer, which is convenient and quick with satisfactory effect.
The diversification of raw materials promotes the diversification of organic fertilizer granulation equipment. Only by choosing the organic fertilizer making machine suitable for its own materials can the whole set of organic fertilizer equipment give full play to its efficiency.

If your production capacity is high, you can choose one or more roller pres pelletizers to combine in the production line. In addition, the production process of roller press granulator is relatively dry, and the organic fertilizer manufacturing process can save energy without drying treatment.
There are different kinds of granulating equipment for different raw materials in organic fertilizer manufacturing process. Many fertilizer investors do not know which granulator equipment they need to use to produce fertilizer. Here we will explain to you the granulation equipment in a very widely used pelletizer - rotary drum granulator.
Drum granulator is a kind of fertilizer granulator equipment widely used in the production of compound fertilizer, organic fertilizer, biological fertilizer, controlled-release fertilizer and other fertilizers. It is suitable for cold and hot granulation in temperature, and suitable for large-scale production of various NPK fertilizers with high, medium and low concentrations in terms of concentration.
Rotary drum granulator uses wet granulation, and the disc granulator is also the granulation method. Through a certain amount of water or steam, the drum pelletizer can make the crushed materials fully chemical reaction after humidity adjustment in the cylinder. Under certain liquid phase conditions, with the help of the rotary motion of the cylinder, the material particles will produce extrusion pressure and agglomerate into balls.
Principle of granulation
Rotary drum granulator manufactured by our factory uses a special rubber sheet lining or acid-resistant stainless steel lining, which has high ball strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, operation and maintenance convenience and other features.
The drum pelleting machine is filled with steam, gas ammonia or phosphoric acid or nitrogen solution, phosphorous ammonia slurry, heavy calcium slurry, and the compound fertilizer granulation process of chemical reaction and heating is completed in the drum; or a small amount is added The process of cold granulation of compound fertilizer with moisture. The material to be granulated is passed through the rotating movement of the cylinder, and the cylinder is not material to produce rolling rotation. Under a certain humidity and temperature, it will be agglomerated into balls to complete the ball making process.
Each kind of fertilizer pelletizer has its own characteristics, and granulation is affected by many factors. The best way to choose the appropriate granulation method and equipment is to compare the actual granules.
Huaqiang organic fertilizer making machine factory has been advocating to serve agriculture well and promote the development of fertilizer enterprises since the production of granulating equipment. Therefore, our factory provides free trial granulation. The so-called free trial granulation means that fertilizer enterprises can provide fertilizer test granulation before purchasing fertilizer pelletizer equipment, so that you can find the most suitable fertilizer granulation equipment.
Huaqiang factory has now formed double roller granulator, hydraulic roller pelletizer, flat die pellet mill, disc granulator machine, drum granulator, organic fertilizer granulator, and fully automatic BB fertilizer equipment. Granules and series of supporting equipment. We can meet the different choices of stand-alone, combined, complete production lines and turnkey projects, so that companies who come to the company to choose equipment can be satisfied. The company takes integrity and pragmatism as the development concept to let every manufacturer who needs fertilizer production equipment , Can choose the ideal granulating equipment in our company.
Here are a few factors that need to be considered when purchasing NPK fertilizer granulator equipment:
1. Raw material factors. According to the characteristics of different raw materials, different granulation methods need to be selected.
2. Product requirements. The particle size of the products obtained by different granulation methods is very different.
According to the fertilizer production process output of their own factory, the user can choose the suitable granulating equipment and the suitable equipment model. Before purchasing the pelletizer machine, it is better to test the machine with raw materials to determine the granulation effect.
Organic carbon fertilizer based on high-quality humic acid and fulvic acid can promote the formation of soil aggregate structure, reduce soil bulk density, increase cation exchange capacity, and regulate soil pH, thus contributing to improving soil water, fertilizer, heat preservation and ventilation capacity. Carbon based fertilizer processed by fertilizer production line can fundamentally improve the problem of soil hardening and soil fertilizer decreasing.
In addition, because humic acid is a high molecular compound with multi-functional groups, it can provide sufficient carbon source and energy for soil microorganisms, promote microbial metabolism and reproduction, increase soil microbial retention, enhance soil microbial activity, and improve soil environment.
Whether it is bamboo biochar, straw charcoal, or tobacco stalk charcoal, the premise must be biomass charcoal. Fertilizers that have nothing to do with biomass charcoal cannot be called real carbon-based fertilizers. The carbon-based fertilizer processed by the organic fertilizer manufacturing process is a high-quality fertilizer.
The focus of carbon-based fertilizer is biomass char, so the main effect must be attributed to biomass char. According to the porosity and strong adsorption capacity of biochar itself, the following points can be briefly summarized here:
1. Maintain soil moisture;
2. Increase microbial activity;
3. Lock nutrients in the soil;
4. Promote plants Growth;
5. Establish lasting fertilizer efficiency.
At present, carbon based fertilizer is also slowly circulating in the market, and its effect has been verified by many agricultural producers. The effect of carbon based fertilizer on improving soil and improving crop quality is significant. The types of carbon based fertilizer products also began to diversify gradually. Biochar can be processed into different types of carbon based fertilizer particles through the pelletizing process of disc granulator, flat die pellet mill and drum granulator.
However, no matter what type of carbon based fertilizer, the ultimate goal is the same. The porous properties and strong adsorption capacity of biochar are used to skillfully combine with various organic matter nutrients, inorganic nutrients and beneficial microorganisms, so as to improve the soil aggregate structure, improve the soil water and fertilizer retention capacity, enhance the microbial activity, and improve the fertilizer utilization rate.
There are many kinds of organic fertilizer granulator, such as double roller granulator, rotary drum granulator, flat die pellet mill and NPK fertilizer granulator. Among them, the disc granulator is very popular because of its many specifications and low price, which can meet the needs of large and small-scale users to process granular fertilizer. Here Huaqiang fertilizer machine factory to introduce the organic fertilizer equipment disc granulator processing pig manure process flow.
The treated pig manure is directly transported to the raw material silo (or mixer).
Pig manure is transported to the disc feeder and evenly added to the rotating disc of the disc granulator; the liquid component or an appropriate amount of water is sprinkled on the disc granulator through the liquid component distributor The material in the disc can meet the liquid phase volume required for ball formation; the rotating disc and the disc edge generate friction and centrifugal effect on the material, causing the material to produce circumferential movement, so that the powder particles can be rubbed and squeezed. Gradually agglomerate into balls due to the difference in particle mass. The resulting gravity and centrifugal effect are also different. When the gravity and centrifugal effect are increased enough to overcome the friction between the particles, they will be thrown out of the disk. Small particles still stay in the disc and continue to gather fine powder particles. The granulation principle of the disc pelletizer is similar to that of the drum granulator, but the disc granulator is more flexible and small in size, so it is suitable for more medium and small fertilizer plants.
The material is transported to the organic fertilizer dryer and exchanges heat with the heat from the hot blast stove.
The material is transported to the hot screening to sort particles, and the fine particles are directly returned to the disc granulator, as the core to continue to participate in the adhesion of particles into balls.
The pellets are transported to the organic fertilizer cooler, and the fertilizer is cooled by natural or strong cooling air.
The organic fertilizer particles are transported to the finished product sieving machine, and the large particles are crushed by the pulverizer and returned to the disc pelletizer to continue to participate in the ball formation.
The qualified products after screening are transported to the coating machine for coating treatment.
Transport to automatic packaging scale for weighing, packaging, and storage.
Drying, cooling and workshop dust are discharged after being treated by cyclone dust collector, dust removal room, and wet washing to reach the standard.
At present, the application of bio organic fertilizer in some green and organic agricultural products has achieved good results, which plays a good demonstration role in the promotion and application of bio organic fertilizer. Although the current agricultural application of bio organic fertilizer enthusiasm is not high, the use rate is relatively low, organic fertilizer is mainly used in vegetables, fruits, Chinese herbal medicine, tobacco and other high value-added cash crops. However, with the improvement of people's consumption level and safety awareness, the demand for green organic agricultural products is increasing. Bio organic fertilizer will become the inevitable choice of agricultural production.
Organic fertilizer making machine is indispensable in agricultural extension of commercial fertilizer. In order to produce special bio organic fertilizer suitable for different crops, it is necessary to select the appropriate granulating machine. Here, two kinds of common granulator equipment are introduced.
How does the organic fertilizer equipment disc granulator process granular fertilizer? Due to the cohesiveness and plasticity of materials, the ball nuclei are bonded to each other and grow up gradually. When the inclination angle, edge height, rotation speed and water content of the ball plate are fixed, the balls with different particle sizes will leave the plate edge and roll down according to different separation angles due to different gravity. In the process of rolling, the water in the ball is constantly discharged from the surface. Due to the cohesiveness of the material and the natural volatilization of the liquid film on the surface, the ball has a certain strength, and then it is discharged from the edge of the disc with the rotation of the inclined disc body. The particles enter the next stage of the fertilizer production line.
Drum granulator is suitable for granulation of organic fertilizer, NPK fertilizer, compound fertilizer and bio organic fertilizer. The internal surface structure of the rotary drum granulator plays a very important role in whether the material can react well in the drum. The drum pelletizer machine designed by us is generally lined with rubber plate to facilitate the normal rolling of materials and realize granulation.
The humus in organic fertilizer increases the content of soil organic matter, which is beneficial to the formation of good soil structure, especially the increase of water stable aggregate structure, so as to improve the tightness, aeration, water retention and heat status of soil, and has a good effect on the water, fertilizer, air and heat conditions that determine the soil fertility. It is beneficial to improve the physical and chemical properties of soil and improve the soil fertility.
When applying organic fertilizer, the consumed organic fertilizer should be continuously replenished. In a few years, soil structure will be destroyed and consolidated by chemical fertilizer alone. On the other hand, the content of soil organic matter is increased, and the soil organic matter is constantly updated. The conversion of organic fertilizer into soil organic matter accounts for about 2 / 3 of the annual formation of soil organic matter.
When installing drum granulator, NPK fertilizer granulator and organic fertilizer granulator, it is necessary to pay attention to whether the main machine is vertical to the ground. After installation, first check whether the screw of the machine is loose. If it is loose, please reinforce it to avoid accidents.
In the process of using the disc granulator, it is inevitable to encounter large or small particles, so how to adjust the particle size of the disc pelletizer? Here is a detailed introduction of the organic fertilizer making machine manufacturer for you.
The disc pan granulator drives the disc to rotate through the motor and reducer. The materials in the disc roll along the disc surface under the action of gravity and centrifugal force. The powder materials collide with each other and finally form particles. With the increasing of particles, it overflows out of the disc.
The particle size is directly related to the rotation speed of the disc pelletizer and the inclination angle of the disc.
First of all, if the rotating speed of the disc is too fast, the more times the material rolls in the disc per unit time, the larger the particles will be, otherwise, the smaller the particles will be. Therefore, whether the rotating speed is reasonable or not plays an important role in the granulation process of fertilizer production line.
Secondly, the inclination angle of the disc of the disc granulator. The larger the inclination angle is, the greater the force of gravity on the material is, and the smaller the effective utilization area of the disc surface is, which directly affects the pelletizing rate of the disc granulator. Therefore, the inclination angle of the disc must be increased while the rotation speed is increased. As the inclination angle of the disc increases, the final rolling speed of the particles will also increase correspondingly, so the inclination angle of the disc should be kept at a pole Limit value to prevent damage to rolling and granulation of materials.
Disc granulator is generally suitable for the granulation of organic fertilizer, NPK fertilizer and compound fertilizer. Compared with rotary drum granulator, its price is lower. It is suitable for granulation process in most fertilizer plants.
The cost performance of fertilizer double roller granulator is mainly reflected in the following aspects.
The double roller press granulator is relatively small in size and occupies a small area, which can effectively save the investment of the processing plant.
Since the roller granulator extrudes materials by gear rolling and volumetric compression, it has a wider range of materials and is especially suitable for the granulation of thixotropic materials.
The bearing frame of the double roller press granulator adopts casting integral parts, which effectively guarantees the stability of power input, and at the same time, it also guarantees the lubrication and sealing performance of the transmission gear.
The organic fertilizer production equipment with roller extrusion pelletizer as the core is mainly composed of: horizontal mixer, double roller press granulator, pan feeder, screening machine, finished product silo, packaging machine, belt conveyor machine. The investment in the organic fertilizer production line is based on the degree of automation of the output, which requires an investment of more than 40,000 US dollars. The complete set of extrusion pelleting equipment has the advantages of compact and reasonable layout, low investment, low energy consumption, small floor space and high output.
The pelletizer machine as the core of fertilizer production line has wide adaptability of raw materials, which is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials, with high product granulation rate.
Roller extrusion pelletizer has good expansibility for capacity requirements. Because of its reasonable structure, the machine can not only meet the small-scale processing requirements of small output and 1.5 tons per hour, but also realize the combination of multiple granulators according to the needs. A set of fertilizer production line can assemble 4 granulators in each group, which can realize nearly 20 tons per hour in each group. It can also be expanded to multiple groups to meet the requirements of greater production capacity.
Our factory provides civil engineering drawings of fertilizer production line, fermentation site planning, production line configuration, NPK fertilizer granulator equipment selection and quotation.
At present, the main granulation methods of organic fertilizer in the market are extrusion granulation and agglomeration granulation.
The common equipment of extrusion granulation is double roller granulator, which is a widely used pelletizer among organic fertilizer granulators. It is an extrusion sliding model and can continuously produce one-time roll forming. In addition, extrusion granulation equipment includes flat die pellet mill and ring die pelleting machine
The common equipments for agglomeration granulation are disc granulator and rotary drum granulator.
Disc granulator is a kind of mature equipment for organic fertilizer granulation. The angle of the disc is an integral arc structure. The material entering the disc is sprayed with an appropriate amount of liquid by the atomizing nozzle. After the granulator rotates, it is made into a finished product. After a certain amount is formed, it is thrown out with the rotation inertia of the disc.
Rotary drum granulator is driven by the main motor to drive the belts and pulleys, which are transmitted to the driving shaft through the reducer, and the split gears mounted on the driving shaft mesh with the large gear ring fixed on the body and work oppositely. The material is added from the feeding end, and it is made into particles by the special structure inside the cylinder, and finally flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be realized.
The two in one npk fertilizer granulator uses the high-speed rotary mechanical stirring force and the resulting aerodynamic force to make the fine powder continuously realize the process of mixing, granulation, spheroidization and densification in the granulator, so as to achieve the purpose of granulation. The granulator is a new type of organic fertilizer granulator developed by our company. Wet fertilizer granulator is widely used in the granulation of organic fertilizer and npk compound fertilizer. Due to the high granulation rate, stable operation, strong and durable equipment, long service life, coupled with the stable base design, its operation is more stable, and is selected as the ideal product by the majority of users.
