Fertilizer Production Line - fertilizer manufacturing process

When many customers purchase fertilizer production equipment, there are many choices and inquiries about the three production lines: disc granulator production line, drum granulator production line and double roller granulator production line. Many people don't understand the principles of these fertilizer production processes and the specific equipment. In fact, a set of fertilizer production line is to select granulator according to the raw materials needed to produce fertilizer products, not just randomly, and the organic fertilizer production line is not fixed. All equipment is determined according to the demand, site and local factors.

Disc granulator fertilizer production line

1. The structure of the disc granulator machine is novel, novel and reasonable, with reduced weight and height. The process layout is flexible and convenient, suitable for the transformation of existing fertilizer plants.
2. The inclination of the large plate can be adjusted. The angle gasket is used for flexible and convenient adjustment.
3. Adopt unique unpowered combination scraper integration to reduce auxiliary power consumption.
4. The big plate is composed of a plate body and a plate section. Reduce the main motor power. The disc joint can be adjusted up and down along the disc body. The end of the disc joint is a side flange, which can ensure that the material ball is not pulled or torn when the material ball is out of the disk.
5. The edge is cleaned by the unpowered combination scraper, the angle is cleared by the angle scraper, and the unique treatment technology of the disc body is used.

Drum granulator fertilizer production line

Rotary drum granulator is suitable for granulation processing of large, medium and small organic fertilizers and NPK fertilizers. It has a wide range of applications and is used to produce high, medium and low concentration special compound fertilizers for various crops. The fertilizer production line has a large output and is equipped with large equipment such as dryers and coolers.

Double roller granulator fertilizer production line

Roller granulator is the key equipment of compound fertilizer granulation. It is matched with corresponding equipment to form a small fertilizer production line to realize continuous and mechanized production of a certain capacity. The fertilizer production line of double roller extrusion granulator does not need to be dried and produced at normal temperature. The product is rolled once to make the product quality meet the technical index requirements of compound fertilizer. It is an updated product of energy saving and consumption reduction in compound fertilizer industry.

What kind of organic fertilizer equipment and process customers choose, the investment and production costs and benefits are different. Therefore, how to choose a reasonable process configuration is an important factor to effectively reduce the cost of equipment when inspecting the production process equipment. This paper introduces the process of organic fertilizer production line with an annual output of 20000 tons designed by Tianci factory.

Process of organic fertilizer production equipment of each process system

① Fermentation system: the fermentation system of organic fertilizer equipment process consists of biological deodorizer, mixing mixer, special compost turner machine and electric automatic control system.

② Drying system: the main equipment includes belt conveyor, rotary dryer, cooler, induced draft fan, hot blast furnace, etc.

③ Deodorization and dedusting system: composed of settling chamber, dedusting chamber, etc.

④ Pulverizing system: including new semi wet material pulverizer, LP chain crusher or cage crushing machine, etc.

⑤ The batching system includes automatic electronic batching system, disc feeder and vibrating screen. The batching equipment can be configured with 6-8 kinds of raw materials at a time.

⑥ The mixing system consists of optional horizontal mixer or disc mixer, vibrating screen, mobile belt conveyor, etc.

⑦ The granulator equipment needed for fertilizer granulator system shall be set according to the raw materials and process. The pelletizer can be selected as follows: double roller granulator, organic fertilizer and compound fertilizer combined granulator, pan granulator, new type organic fertilizer granulator, flat die pellet mill, rotary drum granulator, ball shaping machine, etc.

⑧ Drying system: the organic fertilizer drying system consists of a rotary dryer and a cooler.

⑨ Screening and coating system: it is mainly completed by the roller screen, which can be equipped with primary screen and secondary screen, so that the yield is higher and the particles are better. After screening, the fertilizer coating machine can be used to ensure that the fertility is not released.

⑩ Finished product packaging system generally includes electronic quantitative packaging scale, silo, automatic sewing machine, etc. In this way, automatic and non-intermittent production of organic fertilizer equipment can be realized; the conveyor system mostly uses belt conveyors and screw conveyors.

The raw material has good comminution fineness, which is beneficial to the pelletizing processing of disc granulator machine and other equipment. During the operation of the organic fertilizer production line, considering that the high fineness of the pulverizer will produce certain dust pollution, the dust treatment of the pulverizer should also develop perfect measures to ensure that there is a good environmental condition in the production workshop and a good working environment for the operators.
In the dedusting system, the small production line can adopt the cyclone deduster series products, so as to facilitate the collection and recovery of materials. Cyclone dust collector will not produce high temperature and condensation phenomenon, and the equipment price is relatively low, which saves the equipment cost very well, and is the ideal product of proportioning dust removal system. The process of organic fertilizer production line with an annual output of 20,000 tons is more cost-effective to build a dust removal room, with better dust removal effect, high efficiency and long service life.

Bio-fertilizer is a kind of product that leads to the specific fertilizer effect of crops caused by the life activities of microorganisms, and it is a kind of finished fertilizer in the organic fertilizer production line. It has a huge effect on crop growth and soil nutrition. Here we introduce the application of microbial bacterial fertilizer in the organic fertilizer production line.

1. The effect of energy saving and emission reduction is remarkable. Microbial fertilizers have the effects of phosphorus, potassium and nitrogen fixation, which can improve the fertilizer utilization rate by more than 10% to 30%. The mass production and promotion of such fertilizers can save fertilizer resources and related coal, natural gas, oil and other resources, and help alleviate the energy crisis.

2. Bio-organic fertilizer can reduce farmers' production costs, increase crop output and increase agricultural income. The production cost of compound microbial fertilizers and other series suitable for large-scale promotion of field crops is comparable to or slightly higher than that of ordinary fertilizers. In the processing technology of the fertilizer production line, a variety of nutrients are made into biological compound fertilizer granules by the rotary drum granulator. The results of a large number of experiments and demonstrations on corn, rice, wheat, peanuts and other crops show that microbial fertilizers still have a yield increase effect when the dosage is reduced by 1/3 to 1/2, so that farmers do not increase the cost of fertilizer use Under the application of this microbial fertilizer, higher yields can be obtained, and labor and time are saved, the use is convenient, and greater benefits can be obtained, which can drive the large-scale increase in production of grain, vegetables, fruits, and other economic crops, and solve food production Major issues such as health.

3. Biological compound fertilizer particles can improve the quality of agricultural products. With the continuous improvement of people's living standards, especially people's demand for improved quality of life, they are actively developing green agriculture to produce organic fertilizers and pollution-free green food. In the process of producing green food, chemical fertilizers, chemical pesticides and other chemical substances are required to be used or not used as much as possible (or limited use). It requires the fertilizer to first protect and increase the growth and quality of the application object; secondly, it does not cause the application object to generate and accumulate harmful substances; and it has no adverse effects on the ecological environment. Microbial fertilizers are basically in line with the principles, not only can alleviate or reduce agricultural product pollution, but also improve the quality of agricultural products. The roller granulator we designed is also suitable for the processing of this fertilizer granule. It is extruded and granulated at room temperature without damaging beneficial bacteria.

We often use bio organic fertilizer in agricultural planting, and organic waste is its processing raw material. Chicken manure and crop straw as the main raw materials, after fermentation, they are further made into high-quality organic fertilizer products by drum granulation. The fermentation process can decompose chemical pesticide and chemical fertilizer residues, improve fertilizer quality and increase fertilizer disease resistance.

Bio organic fertilizer is rich in nutrients, which can improve the soil and improve the soil consolidation caused by the application of chemical fertilizer. Improve the physical and chemical properties of soil, enhance the ability of soil water conservation and fertilization. According to the equipments required for biofertilizer production, the production process can be divided into flat composting and tank fermentation.

The factors affecting the safety of bio organic fertilizer are as follows

1、 Organic pollutants: these pollutants come from sludge, crop straw, etc.
2、 Antibiotics, organic arsenic: This is extracted from a variety of antibiotics widely used in animal husbandry, most of which are excreted with feces and urine in the original form of drugs. Pig manure, chicken manure and other livestock wastes are widely used in agricultural production as raw materials of bio organic fertilizer. The amount of antibiotics entering the soil every year is no less than that of pesticides, and enters the food chain through soil fertilizer. Some veterinary drugs are more toxic to the metabolites excreted in feces.
3、 Heavy metal pollution: the main pollution sources are mineral raw materials for production, smelting waste acid, heavy metal contaminated sludge, etc. Heavy metal pollution is common in phosphate fertilizer products and compound fertilizer products. In addition, the content of inorganic impurities such as salt in some chemical fertilizers is too high, which will not only cause soil salinization, but also cause seedling burning or yield reduction.
4、 Another type is pathogens and eggs, which are derived from untested microbial strains and can cause infection in humans or animals. Unsafe factors in the use of strains are also gradually expanding, and strains harmful to humans, animals and plants may flow into production. Some conditional strains may flow into the production chain, resulting in safety problems.

In order to ensure the quality of organic fertilizer, in the production process of bio organic fertilizer, it is necessary to ensure that the organic fertilizer is fully decomposed by high temperature fermentation. The raw materials are processed according to the production process. We provide a complete set of NPK fertilizer manufacturing process and organic fertilizer equipment.

After three or four days of fermentation, you will find that there is basically no odor in the feces. After the fermentation of sheep manure, the color of the fermentation pile will be darker, and the color of the pile will be brown after the fermentation. When the fermentation of sheep manure organic fertilizer is completed, the compost can be crushed and packaged, or it can be made into granules by disc granulator machine for further processing.

The key to fermented organic manure

1. Moisture adjustment. If the moisture is high, add some dry sheep dung or rice waste, straw, wheat straw, mushroom residue, residue and other agricultural waste. Usually the water of sheep manure is relatively small, and it needs to be adjusted by spraying water or adding fresh cow manure, chicken manure and pig manure.
2. Use a compost turning machine. If you want to decompose and rot sheep manure quickly, you must turn the materials regularly to make the bacteria and enzymes decompose and rot sheep dung protein quickly.
3. Pay attention to the specifications of the fermentation reactor. It is also important to note here that the pile should not be too small or too high, and it is not conducive to fermentation. Can choose to pile up in piles for aerobic fermentation of compost. It is also possible to build fermentation tanks to pile up materials.

Organic fertilizer production line processing sheep manure

Only by strictly restricting the amount of fertilizers and pesticides, improving the soil, and reducing the amount of drug residues in the soil can the farmer produce high-quality, safe and green products that are popular at home and abroad. The green active natural organic fertilizer is a new type of biologically active fertilizer, which has the characteristics of no pollution. It uses organic fertilizer as a substrate and carrier, and the sheep dung after fermentation can be used as organic matter. Add appropriate amount of inorganic elements to the organic fertilizer, and then add beneficial microorganisms that are beneficial to soil structure, crop absorption, element release, etc., and bioactive fertilizers can be obtained by processing on the organic fertilizer production line.

We provide a variety of organic fertilizer production equipment and processes, including roller granulator, flat die pellet mill, drum dryer, cooler, crusher and a complete set of sheep manure organic fertilizer production line.

In the NPK fertilizer manufacturing process, a coating process is added to make a slow-release fertilizer. Slow-release fertilizer is also called controlled-release fertilizer. The release rate of nutrients in fertilizers can be controlled to a certain extent for continuous absorption and utilization by crops. After the fertilizer is coated, it can reduce the loss of fertilizer nutrients, especially nitrogen, in the soil. Can reduce the frequency of fertilization, save labor and cost. To increase crop yield and income, the application of slow-release fertilizer can improve crop resistance to disease and lodging.

The amount of coating agent is controlled according to the length of particle preservation in NPK fertilizer manufacturing process. So what are the precautions about the coating of NPK fertilizer granulation?

Fertilizer granule coating machine is composed of screw conveyor, mixing tank, oil pump, main machine, etc. It can effectively prevent the caking of organic fertilizer and compound fertilizer, and is an effective coating fertilizer manufacturing equipment.

Precautions for the operation of fertilizer coating

1. Do not remove the protective device when the coating machine is running.
2. When the coating machine is running, it is forbidden to drill under the machine body.
3. It is forbidden to carry out internal inspection and repair when the coating machine is in operation.
4. Do not touch the motor and wires without insulating gloves.
5. When checking the furnace and coating machine, it is forbidden to use mobile electric lights with voltage higher than 12 v.
6. If there is no perfect grounding wire, it is forbidden to start the coating machine. If there is current on the equipment, stop the machine immediately until the grounding wire is repaired.

The production capacity of fertilizer drum granulation process is 1-20T / h, and the application scope of fertilizer granule coating machine is: peat, sludge, chicken manure, livestock manure, lignite, filter sludge of sugar mill, papermaking sludge, wine, straw, bean dregs, etc.

With the increasing attention to the safety of agricultural products, and the increasingly obvious harm of chemical fertilizer to the soil, organic fertilizer has become the widely used fertilizer in agricultural production. What aspects need to be inspected for investment in organic fertilizer production line project?

1. Invest in livestock manure organic fertilizer equipment, control the risk of early investment in organic fertilizer production line project, select appropriate fertilizer equipment manufacturer, and control the investment risk of equipment and construction plant to a certain extent.

2. What are the raw materials for the processing of livestock manure organic fertilizer equipment? What do animal farms raise? There are many pig, duck, chicken, sheep and cattle farmers in various regions. The waste produced by these farming industries is the main raw material for processing organic fertilizer. We should choose the right cooperators according to the market situation and our own position, not blindly following the trend, according to our local climate, temperature and water conditions.

3. The equipment for processing livestock manure organic fertilizer is an environmental protection equipment. There are many kinds of organic fertilizer production equipment. Different processing stages of organic fertilizer need different machines. Solid liquid separator, organic fertilizer throwing machine, crusher, disc granulator machine, dryer, cooler, packaging machine and so on. The configuration and equipment selection of organic fertilizer production line should be determined according to the situation. Different raw materials, different pelletizing equipment, we provide organic fertilizer granulator, rotary drum granulator, flat die pellet mill and other machines.

The organic fertilizer tossing function can effectively mix livestock manure, sludge, microbial agent and straw powder. To create a better aerobic environment for material fermentation. It can heat up in one day, deodorize in 3-5 hours, sterilize and make fertilizer in seven days. It is not only faster than other mechanical means of fermentation, but also more efficient. "Modern, ecological and recycling" is the production line's use of automatic and modern technology to turn organic waste into treasure, and realize the energy and resource recycling of livestock manure.

Sulfur coating technology is a kind of microcrystalline polymer material with sulfur and paraffin as main raw materials on the basis of large granule urea, so as to achieve slow controlled release of nitrogen nutrients. Sulfur coated urea should meet the following three indicators:

1. The content of N was 31 / 34 / 35 / 37.
2. Under the condition of 38 ℃ still water and constant temperature, 10%, 15%, 20% and 25% of total nitrogen content were released in 24 hours.
3. 60% - 70% of total nitrogen was released in seven days.

The key technology of sulfur coated urea coating can be used in NPK fertilizer granulation, drum granulation and other slow and controlled-release fertilizers, realize curtain coating granulation of various solid granular fertilizers, and produce various slow and controlled-release fertilizers such as super granular urea, sulfur coated compound fertilizer, lignosulfonate urea, humic acid urea and water-soluble resin.

The coated controlled-release fertilizer can give full play to the fertilizer efficiency and utilization rate, and has important economic and ecological benefits. NPK fertilizer manufacturing process adopts coating treatment, which greatly improves the controlled release time of fertilizer. The controlled release time of coated controlled-release fertilizer can be as long as 3 months to 2 years due to the technology setting, which is called slow-release fertilizer, long-term coated fertilizer and coated controlled-release fertilizer. The shape of fertilizer is good after being treated by rotary drum granulator.

Because the efficiency of coated controlled-release fertilizer can be increased by 1-2 times than that of general fertilizer, and about one third of nitrogen fertilizer can be saved when it is used in rice farming. If we calculate the cost of fertilizer, the loss of fertilizer, the amount of fertilizer, labor and environmental protection are more important. The price difference between the two has been reduced obviously. The prospect of coated fertilizer processing by fertilizer manufacturing equipment still has its advantages and merits.

The drum granulator is a commonly used fertilizer production machine. In the steam granulation process, the pellets are mainly clad, so the material circulation volume should be larger, so this can provide a larger coating process Nuclear, and the water injection volume should be smaller, so that the water absorption of the core can be reduced. When pelletizing by bonding or "gathering", the moisture content of the material is smaller, because at this time, the material in the rotary drum is 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.

The main structure of the rotary drum granulator is an inclined rotary cylinder, 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 of the drum granulation production process to increase the thickness of the material layer and extend the residence time in the main drum. In other occasions, a spiral discharge ring is often used to convey boredom to the drum. At the end of the screen. Sometimes the cylindrical screen is integrated with the drum to form a product discharge port.

In the whole NPK fertilizer manufacturing process, 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.
