The reducer of the drum granulator is driven by a belt driven by a motor. There is a pinion on the reducer shaft, which is exactly in line with the teeth on the ring gear outside the body. The cylinder and the reducer move in opposite directions. In organic fertilizer production line, the materials are sent to the cylinder end of the machine by the silo or conveyor. The granulator makes the materials into granular materials in the cylinder, and the materials conforming to the finished products are discharged from the discharge port at the other end. The continuous operation of the rotary drum granulator can realize the large-scale production of the organic fertilizer production line.
Rotary drum granulator can rotate the cylinder with less power. The outside of the machine is made of wear-resistant steel, which effectively prolongs the use time of the equipment.
The granulation principle of drum granulator is different from that of roller press granulator, it can make materials roll through chemical reaction. Under the action of certain liquid, using the rolling of cylinder, a sphere is formed by extrusion between material and small particles. Roller granulator is used to extrude particles by external force
The machine is supported by the most energy-saving supporting wheel bracket, which is made of high-quality carbon steel and can fully bear the weight of the cylinder. Considering the large friction between the cylinder and the supporting wheel, we specially use more wear-resistant materials in this part. On the one hand, it can improve the safety of the equipment, on the other hand, it can also improve the stability.
The transmission device is an important part to provide the main power for the machine. The gear ring on the cylinder is driven by the motor and reducer on the rack. The rack is welded with professional high-quality channel steel which is not easy to deform. The transmission device of the machine is more safe and stable.
In chemical processing industry, rotary drum granulator is widely used in organic fertilizer production line and NPK fertilizer production line. In the granulation process of the drum granulator, the coarsening in the pellet is mainly in the form of cladding, so the material circulation volume should be larger, so as to provide a coarser core for the cladding process, and the water injection volume should be smaller, so as to reduce the water absorption of the core. When pelletizing by bonding or "gathering", the materials are smaller, because the materials in the drum are mainly composed of fresh materials with small particle size and mutual bonding. The liquid ratio required for bonding should be large, because the space between the fine powder particles to be bonded with each other should be filled with water.
Working Principle
The main structure of the rotary drum granulator is an inclined rotary cylinder, and the drive can be constant speed or variable speed. When the liquid content of the feed powder is appropriate, agglomeration occurs and rolls in the drum. The drum has a certain slope, and the included angle between its axis and the horizontal is below 10 °, which can help the material roll along the long direction of the drum. The feed end is often equipped with a retaining ring to prevent the material from flowing back. A retaining ring can also be installed at the discharge end to increase the thickness of the material layer and extend the retention time in the main drum. In other occasions, the spiral discharge ring is often used to convey the boring to the screen at the back of the drum. Sometimes, the cylindrical screen and the rotary drum are integrated to form a product discharge port. The feed consists of fresh material and circulating material, and the feeding system can adopt belt conveyor, chute pipe or other similar equipment. The bonding liquid is injected either before the solid material enters the rotating cylinder or immediately after the solid enters the rotating cylinder.
Different from the roller granulator, the inner surface structure of the drum plays an important role in whether the material can react well in the drum. The inner part of the steel rotary drum is usually made of hot expanding metal. The function of various internal scrapers is to keep a certain thickness of the material on the inner surface of the rotary drum, so that the material layer is uniform, so that the material can roll and turn normally in the rotary drum. Rubber baffles and linings as well as external vibrators are used to prevent the accumulation of fertilizer during granulation.
Although the disc granulator machine has a slightly smaller output than the rotary drum granulator, it is still the main equipment for compound fertilizer production, and the fertilizer granules produced have a smooth appearance. Therefore, many companies have retained disc granulators in organic fertilizer production. Now that the disc pan granulator is still in use, what are some tips when choosing disc granulation equipment?
When choosing a device, you must first choose a regular manufacturer. This is the most important, because even if there is a problem with our device in the future, we can find them and solve the problem. Our company's consistent style is to provide follow-up guarantee services, so no matter what the customer has in the equipment we produce, we will seriously solve the problem until the customer's problem is solved.
Pay attention to the quality of the equipment when purchasing the equipment. When selecting the organic fertilizer production line, we must go to the manufacturer to inspect it. During the inspection process, we should have a general understanding of the strength of the company and the quality of the equipment produced Wait.
There are two kinds of granulation processes for granular fertilizer such as organic fertilizer and compound fertilizer: one is the extrusion granulation process developed from feed granulation (common granulation equipment includes roller granulator and flat die pellet mill). The other is the wet granulation process (the typical granulation equipment includes disc pan granulator and roatary drum granulator). The particles produced by the extrusion granulator are elliptical or cylindrical, and the particles produced by the wet granulation process are spherical and of different sizes.
As a fertilizer processing unit, the quality of production equipment and the advanced degree of production technology are the reliable guarantee of production efficiency and products. However, production safety is the lifeblood of any enterprise. Only the safety production order can realize the three principles of quality, efficiency and development.
In the production of compound fertilizer, the basic raw materials, such as nitrogen, phosphorus and potassium, or their solutions and molten slurry, are mixed in a certain proportion, and then the finished granular compound fertilizer is obtained through granulation, drying, cooling and screening. Due to the different physical and chemical properties of raw materials, there is a large number of solid material flow in the production process, involving more mechanical transmission and conveying equipment. Urea and compound fertilizer have certain thermal decomposition properties, as well as a large number of gas dust spillage, so it is necessary to fully understand its safety characteristics.
Disc granulator machine: the rotation of the disc body makes the materials adhere to each other to form small balls. Due to the difference of particle mass, the gravity and centrifugal effect are also different. When the gravity and centrifugal effect increase enough to overcome the friction between particles, they will be thrown out of the disk, and the smaller particles will remain in the disk to continue to gather fine particles.
Rotary drum granulator: This machine is suitable for the production and processing of NPK compound fertilizer with large output and similar principle. Different from the traditional granulation process, the inner lining of the rotary granulator provided by us is unique. When the cylinder is turned from the bottom to the top, the inner lining will sag due to the self weight, and the materials attached to the inner lining will fall down due to the gravity, so as to achieve the function of automatic cleaning and caking.
There are many different types of compound fertilizer granulating equipment, such as disc pan granulator, tooth-drum granulator, double roller granulator, rotary drum granulator, etc. Many users do not know their own production when buying What kind of granulator equipment should be used for fertilizer? Then we will introduce to you one of the equipment for granulation of compound fertilizers-rotary drum granulator.
Drum granulator is a kind of granulator commonly used in the production of NPK compound fertilizer, biological fertilizer, controlled-release fertilizer and other fertilizers. It is suitable for the large-scale production of cold, hot granulation and high, medium and low concentration NPK fertilizer production line. Rotary drum granulator adopts special rubber plate lining or acid resistant stainless steel lining plate, which has the characteristics of high ball forming strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, convenient operation and maintenance, etc.
The main working mode of the drum granulator is wet granulation of pellets. Through a certain amount of water or steam, the crushed materials can be fully chemically reacted after being humidified in the cylinder. Under a certain liquid-phase condition, with the help of the rotating motion of the cylinder, the extrusion pressure between the particles of the materials can be generated to agglomerate into a ball. Steam, gas ammonia or phosphoric acid or nitrogen solution, phosphoric ammonia slurry and heavy calcium slurry are introduced into the drum granulator to complete the chemical reaction and heating compound fertilizer granulation process in the drum, or the cold granulation process of compound fertilizer supplemented with a small amount of water. The materials to be granulated are rotated by the cylinder. Finally, the fertilizer is agglomerated into balls under certain humidity and temperature, and the pelletizing process of NPK fertilizer production line is completed.

So we become a good helper for users to get rich, and consider for users. Over the years, we have been summing up our experience and improving our production process, and now we have both affordable and high-quality equipment.
Disc granulator can process fertilizer into granules, and fertilizer granulation is an important process in organic fertilizer production line. The quality of granulation affects the quality of final fertilizer.
Organic fertilizer is mainly derived from plants and animals. It is a carbon-containing material that is applied to the soil to provide plant nutrition as its main function. The waste material is processed through the organic fertilizer production line, eliminating harmful substances therein, and rich in a large number of beneficial substances.
The common way of fertilizer granulation in the market is extrusion granulation and wet granulation, that is, roller granulator, disc granulator and rotary drum granulator are used as granulation equipment. Why do we use disk granulation mechanism to make granular fertilizer in the production of organic fertilizer? What are the advantages of granular fertilizer compared with powder fertilizer?
The granulation of fertilizer improves the agricultural technology. The granulation of fertilizer plays the role of slow release of fertilizer efficiency, and the fertilization is convenient and not easy to be blown away by the wind.
Fertilizer with low water solubility usually needs to be milled into small particles to ensure that it can be effectively and rapidly dissolved in the soil and absorbed by plants.
Some inorganic components can be added to the organic fertilizer production line to improve the fertilizer efficiency of the organic fertilizer, and if inorganic components are added to the powder fertilizer, it is easy to absorb moisture and agglomerate. Set the proportion of formula fertilizer in the production line, the disc granulator can mix the raw materials evenly to make solid particles.
The control of fertilizer particle size is very important for the storage and transportation of fertilizer. Good granulation makes organic fertilizer not easy to agglomerate and has better transport performance.
The pelletizing equipment of disc granulator is used for pelletizing the raw materials after formulation in the organic fertilizer production line. Fertilization can significantly increase the content of alkali hydrolyzed n, available P and available K in the soil, the application of organic fertilizer can significantly increase the content of alkali hydrolyzed n in the soil, the application of chemical P fertilizer can promote the accumulation of available P, and the combination of organic fertilizer and chemical K fertilizer can rapidly increase the content of available K in the soil.
The traditional chemical fertilizer, such as N or a certain proportion of N, P, K compound fertilizer, is coated with a special biological or chemical water soluble polymer film. Based on the characteristics of film thickness, particle radius, diffusion coefficient, nutrient composition and dissolution, the release rate and amount of fertilizer nutrient are controlled according to the time of growing nutrient demand of crops, so that the release rate of fertilizer nutrient can fully match the needs of crops.
Reduce human management cost
After the fertilizer is made into particles by the rotary drum granulator, the coating process is carried out. The coated fertilizer greatly reduces the times of artificial labor fertilization, reduces the amount of fertilizer used, and reduces the loss of fertilizer, thus saving time, labor and money.
Increase of economic benefits
The coated controlled-release fertilizer can improve the fertilizer utilization rate, which is the key to save agricultural cost and increase product benefit. Before the fertilizer is coated, it should be pelletized by disc granulator machine. Therefore, the effect of granular fertilizer is long-term and stable. The energy of fertilizer can continuously supply the demand of nutrients for the whole growth period of crops. The benefit of coated controlled-release fertilizer is 1-2 times that of conventional fertilizer, which can improve the output and quality of agricultural products and increase the added value of fertilizer to crops.
Safe and harmless
Coated controlled-release fertilizer has low salt index, even if it is used in large quantities at one time, it will not burn crop seedlings. It can also solve the difficulty of topdressing in the later stage under the condition of dense crops and save labor consumption. More importantly, the coated controlled-release fertilizer is suitable for different types of plants and soils, and effectively prevents the acidification and salinization of natural land.
Human beings often face the dilemma of choice. The manufacturing cost of the coated controlled-release fertilizer is 3-4 times higher than that of the ordinary fertilizer, so most of the coated controlled-release fertilizer is only used in high unit price horticultural flowers and fruits and agricultural products. In addition, the investment in fertilizer production machine is relatively large. In order to avoid risks, manufacturers will choose simpler equipment. However, the effect of slow-release fertilizer is still desirable.
Double roller granulator is a new generation of pellet machine developed and designed by the organic fertilizer manufacturing industry.The basic principle of extrusion molding is used to form fertilizer granules with a diameter of 2.5-20 mm many times. The granulation rate of this machine is higher than 86%. The double roller press granulator is a common processing method in the organic fertilizer production line without drying (water content 3% -7%) at room temperature. Roller granulation machine has low cost and fast granule processing. As an organic fertilizer project investment, it can produce excellent economic benefits.
Double roller press granulator is applied to the processing technology of non drying fertilizer particles, which can produce fertilizer particles in one extrusion, with low cost. The granulator manufactured by Tianci fertilizer equipment factory adopts reliable motor. There is no discharge of three wastes in the production process of the machine. The plastic processing is stable and the maintenance is simple. Compared with the rotary drum granulator, it has the advantages of low energy consumption, good component structure, good technology and good economic benefits.
Roller granulator is used for compound fertilizer, organic fertilizer, fine feed and other raw materials. It can be used to produce and process a series of fertilizer products with various concentration values (including organic fertilizer, inorganic fertilizer, biological fertilizer and magnetic fertilizer), ammonium bicarbonate fertilizer, ammonium persulfate fertilizer, etc., which are common in the production and manufacturing of fertilizer industry.
Frame part: the main body of the whole ammonium sulfate granulator is installed and fixed on the frame. The frame of the machine is welded with channel steel, with stable structure and corrosion-resistant materials, so as to extend the service life and meet the specific process requirements.
Transmission connection part: the motor drives the pulley, V-belt and reducer to make the head work. In addition, the chain wheel and chain constitute the transmission chain to the broken and separated parts.
Working parts of the head: it is transmitted to the transmission roller shaft through the pin shaft through the coupling, and ensures the synchronous operation of two roller shafts through a pair of open gears.
Crushing and separating part: the material flows to the crushing chamber at the lower side after being extruded by the roller, and the particles and returned materials can be separated by the rotation of the double axis hammer.
The roller granulator is not only suitable for the direct granulation of livestock manure, sugar factory filter mud, municipal sludge, straw, peat and other coarse fiber organic wastes with water content of about 30%, but also suitable for the extrusion granulation of compound fertilizers such as ammonium chloride and ammonium bicarbonate. The pelletizer can extrude elliptical granular compound fertilizer and feed.
The fertilizer production process of roller press granulator makes the pelletizing rate reach over 95%, the extruded particles are round and standard, and the strength is high. The use of rotary drum granulator requires drying, cooling and other processes, while the double roller pelletizer has a short fertilizer production process and low operating cost, which is particularly suitable for dry granulation. The crushing and separating part of extrusion granulation particle: the material flows into the crushing chamber at the lower side after being extruded, and the ball and the returned material are separated and re granulated through the rotation of the biaxial hammer, so that the raw material for granulation can be fully utilized.
In the organic fertilizer production line, the material is required to have a certain viscosity. Some raw materials are loose after fermentation, and it is not easy to granulate. Therefore, some moisture or binder must be added to increase the viscosity of the material. Moreover, some fertilizer production lines are produced by a non-drying normal temperature process, and the double roller extrusion granulator are suitable for granulation of materials with relatively low water content. If the moisture content of the material is too high, some dry materials can be added in an appropriate amount to neutralize the moisture content. If the water content is too low, the appropriate amount of water can be added to make the material easy to granulate.
All working bodies of the roller extrusion pelletizer machine are installed and fixed on the frame. The machine frame is welded by medium carbon steel plate and channel steel. Through strict quality control and specific process requirements, the purpose of the machine is achieved. Lifting holes are provided in the middle of the four corners of the frame for loading, unloading and transportation.
The double roller extrusion granulator is suitable for the granulation of various high, medium and low content compound fertilizers, with high particle strength and beautiful appearance. Meet the requirements of energy saving, low carbon and environmental protection in organic fertilizer industry. For most fertilizer manufacturers, this is a popular fertilizer manufacturing equipment.
The granulator can be used for continuous production and processing of various raw materials in fertilizer plant. Ammonium chloride, ammonium sulfate, potassium chloride, magnesium sulfate and other high, medium and low concentration compound fertilizers and chemical raw materials, as well as inorganic fertilizer raw materials, organic fertilizer raw materials, organic biological fertilizer raw materials, etc.
Mainly through external pressure, the material is forced to pass through the gap between two rollers rotating on the opposite side, and is compressed into sheets. In the rolling process, the actual density of the material can be increased by 1.5-3 times, reaching a certain strength requirements. Compared with drum granulation and other pelletizer, the roller extrusion granulator has the advantages of low price, small floor space and flexible operation. By changing the slotting form of the roll surface, the sheet, strip and oblate materials can be obtained to meet the needs of customers. Dry powder raw materials can be granulated directly without subsequent drying and drying process.
