Fertilizer Machine Manufacturer Introduces How to Produce Compound Fertilizer Granules

The common granulation processes of compound fertilizer include tower granulation, rotary drum granulation (NPK fertilizer production line), spray granulation and so on. As fertilizer machine manufacturer, let’s introduce these production processes from the perspective of fertilizer production.

 

  1. High tower granulation process is mainly used for the production of high concentration nitro compound fertilizer. It can directly use concentrated ammonium nitrate solution, eliminating the links of spraying granulation, and granular compound fertilizer eliminates the process of crushing operation. At the same time, the compound fertilizer granules produced by the high tower granulation process are very uniform, the qualified rate is very high, the quality is good, easy to dissolve, and the caking phenomenon will not occur.

 

  1. Rotary drum granulator has little restriction on compound fertilizer formulation, high production yield, low investment and construction speed. It is favored by investors of small and medium-sized compound fertilizer plants and widely used in compound fertilizer production. The complete drum granulation process is a NPK compound fertilizer production line, which includes fertilizer granulator, automatic batching system, mixer, crusher, drum dryer, drum cooler, coating machine, packaging machine and other equipment.

NPK compound fertilizer production line

 

  1. The spray granulation process adopts the slurry method. The slurry is sprayed into the equipment by heating and pumping, so that the moisture in the slurry is vaporized and separated, and the retained solid forms a granular compound fertilizer. This kind of process is widely used in large-scale compound fertilizer production. Its advantages are that it can be used to produce NPK compound fertilizer, and can also be used to produce ammonium phosphate compound fertilizer. At the same time, it has less energy consumption, large production scale and low production cost. The quality and strength of the products are very good.

Common problems in the production of organic fertilizer

Fermentation and granulation are the two most critical steps in a complete organic fertilizer production line, so fermentation turners and organic fertilizer granulator machine play an important role in all organic fertilizer plants. Here we will discuss the problems that may be encountered in the production process of these two key links.
organic fertilizer production line machines

There are many types of organic fertilizer fermentation turning equipment, and the models of the same type are also different in size. We can choose according to the production needs. In the current market, the widely used one is trough fermentation, and the representative one is the ordinary trough turning machine, which is suitable for the small-yield organic fertilizer production line and biofertilizer project. When in use, the stacker should be parked in the fermentation open space, and the piled teeth should not be immersed in the raw materials. After the turning teeth are completely rotated, the walking motor can be turned on and the fattening operation can be started slowly. This avoids the large resistance encountered when the turning motor is started, and has some unnecessary consequences; sometimes in order to improve the fermentation tank utilization rate and the high accumulation of fertilizers can also lead to excessive resistance when turning over, with serious consequences.

The importance of organic fertilizer granulator machine in organic fertilizer production line is self-evident. The key to improving product yield and output is organic fertilizer granulation equipment. Depending on the raw materials, we can choose the right granulation machine, but then we have to find ways to use these machines to give them the greatest capacity advantage. Through the principle of granulation, we have learned that the powder raw materials are bonded by water to form spherical particles, so the two indicators of controlling the moisture content and making the moisture content uniform are the key factors for improving the yield. When the moisture content is low, the granulation rate is low, the moisture content is high, and the large particles are large, and the water is not uniform, and the particle size is small and the yield is lower. Therefore, we should constantly explore the optimal moisture content during the production process to ensure high-yield production.

In an organic fertilizer production line, there are many types of equipment such as fermentation turner, organic fertilizer pulverizer, mixing, fertilizer granulator machine, tumble dryer, rotary cooler, drum sieving machine, automatic packaging machine, etc. But here we only list the related topics of the fermentation turner and the fertilizer granulator machine. First, because of the importance of these two devices in the whole set of organic fertilizer equipment, and second, the experience required for the two equipments is relatively high. More, it is necessary to constantly explore and summarize in the future production process to maximize the efficiency of the equipment.

Production process of potassium chloride by disc granulator machine

In the production of potassium chloride granular fertilizer, fertilizer granulator can be used to granulate powder. The particles produced by disc granulator are spherical and have good strength, which can be widely used in agricultural production.

 

Disc Pan Granulator

In the granulation process of disc pan granulator, it is necessary to add a binder to make the granules shape. Binder can be compounded by common inorganic minerals in a certain proportion. Binder has synergistic effect when potassium chloride is pelleted. The effect of pelletizing rate and particle strength is good when the binder is used for pelletizing. Potassium chloride was granulated by disc pan granulator machine, and the granules were spherical.

 

NPK Fertilizer Production Line

NPK fertilizer production line deals with potassium chloride fertilizer. First, all raw materials are mixed by the batching system, and the material is crushed by chain mill to the appropriate size. The disc granulator makes the powder into granules. After drying and cooling, the granules of potassium chloride are coated with protective film by the fertilizer coating machine to complete the granular processing of potassium chloride.

Disc Granulator NPK Fertilizer Production Line

 

When applying potassium chloride, attention should be paid to the appropriate period of potassium application. Generally, the application period of potassium fertilizer should be early or not late, and should be used as base fertilizer and early recovery period. When the application amount of potassium fertilizer is less, it can be used as base fertilizer once, and when the application amount of potassium fertilizer is more or the soil texture is lighter, the application effect is better divided into base fertilizer and topdressing fertilizer. Soil nutrients and fertilization status should also be taken into account in determining the suitable application period of potassium fertilizer. In severe potassium deficiency soils, all potassium fertilizers should be used as base fertilizers in medium soil potassium supply, and suitable organic fertilizers should be applied as base fertilizers, combined with topdressing.

 

Note the method of application of potassium chloride. The concentrated application of potassium fertilizer is beneficial to improve its utilization rate and obtain better results. However, it is not advisable to have direct contact with seeds or seedlings. For general crops, a combination of soil fertilization and foliar fertilization can be used.

What is the reason that the compost turner machine is used for manure composting?

As a new type of compost turner machine, Double-screws Turning Machine is widely used in animal manure organic fertilizer production and bio-organic fertilizer production. It is the core equipment of aerobic dynamic composting, and it is based on the organic Fertilizer manufacturing process and NPK fertilizer production machinery equipment family. The unique mechanical design and practical mechanical properties are rapidly multiplying, and it is the best substitute for replacing the manual and forklift materials. It is the mainstream product of the pre-fermentation application of organic fertilizer production line and biofertilizer project.

The Double-screws Turning Machine comprises a traverse device, a traveling device and a tumbling device, wherein the tumbling device comprises two reducers fixed to the frame, a screw shaft connected to the respective reducer via a coupling member and fixed with a spiral blade. When the device is walking on a specific track, the screw shaft will no longer work, and the screw shaft will automatically rotate to move against the work when walking to the effective work surface. The fermentation rate is increased, the compost is rapidly decomposed, the odor is prevented from being generated, and the fermentation time is shortened.
Double-screws Turning Machine performance characteristics:

  1. Fully stir the doping to make the material meet the granulation demand quickly.
  2. Due to the large stacking force, the material is supplemented with more fresh air, which helps the aerobic microbial fermentation to heat up, and constitutes a process of high-temperature exchange, which helps all kinds of beneficial micro-bacteria to develop and multiply in the temperature range where it adapts.
  3. The turner system can process the material into small clumps, making the thick and dense material pile loose and elastic, and forming a suitable porosity.
  4. After the raw materials are turned over and fermented, there is certain water content. The consumption of raw materials by a large amount of microorganisms generated after turning over the piles will also release the water in the carrier. Therefore, as the fertilizer process reduces water, in addition to the evaporation of the heat transfer composition, the turning machine flips the raw materials to form a forced water vapor volatilization.
  5. Achieve special requirements for the composting process. For example, the breaking of the raw material, the shape of the raw material pile or the quantitative shift of the raw material is achieved. As one of the important equipments in the fermentation equipment and organic fertilizer production process, the turner has been at the forefront of the development of the times, making great contributions to the organic fertilizer production line andbiofertilizer project.

The working principle of the disc granulator in the fertilizer production line

The disc granulator machine is mainly used in the NPK fertilizer production line and organic fertilizer production line to produce various granular products; it’s also used in pharmaceutical products, fertilizers, feeds, etc. Adopting the overall arc structure, the granulation rate can reach above 93%. The granulation tray has three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

Disc fertilizer granulator machine working principle:
The raw meal powder is uniformly wetted by the atomized water in the mixer to form a spherical core having a uniform particle size, and then fed into a ball plate for ball formation. The moisture of the ball should be controlled at 12-14%. Most of the water should be added in the twin-shaft mixer. Only a small amount of supplementary water is added to the ball plate, and the amount of water added is controlled to be about 0 to 3%. The dry powder granulation is directly added to the ball-forming plate, and the proper amount of water is sprayed. The raw material nucleus enters the spherical disk and is subjected to centrifugal force, friction and gravity in the disk, and moves along the parabola. Due to the cohesiveness and plasticity of the material, the cores are bonded to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the height of the disc edge, the rotation speed and the moisture are constant, the balls of different particle sizes roll downward from the edge of the disc at different disengagement angles due to different gravity. During the continuous rolling process, the ball continuously discharges the water in the ball out of the surface. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the ball has certain strength, and then the disk is rotated with the tilting of the disk. The sides are discharged out of the pan.

Disc granulator performance advantages:
1. The raw materials are suitable for a wide range of applications. They can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce various concentrations and various types (including organic fertilizer, inorganic fertilizer, and magnetic fertilizer etc.) of compound fertilizer.
2. The disc granulator is light in weight, low in height, and flexible in process;
3. The machine has simple structure, convenient adjustment and superior performance.
4. The use of unique unpowered combination scraper integration reduces auxiliary power consumption.

5, high ball formation rate, large rounded particle strength, intuitive operation, easy maintenance and so on.

Fertilizer granulator machine is the core equipment for fertilizer manufacturing process. As one of leading fertilizer machine manufacturers in China, in addition to the disc granulator, we also produce other types of fertilizer granulator machines, and other equipment such as compost turning machines, mixer machine, crusher machine, etc.
