How to Compress and Granulate Organic Fertilizer in Organic Fertilizer Production Line

At present, the use of organic waste to produce organic fertilizer through biological fermentation has been rapidly developed, because it can realize the harmless and resourceful treatment of organic waste. However, most of the organic fertilizers obtained by biological fermentation are in the form of coarse powder or irregular small pieces, which are very inconvenient to use, especially unfavorable for large-area machine-sowing. Today, the FPC organic fertilizer manufacturer will explain how the organic fertilizer production line compresses and granulates the organic fertilizer.

The existing technologies for making the coarse powder or irregular small block organic fertilizer after biological fermentation into spherical granular organic fertilizer mainly include the following:

  • Some manufacturers use traditional disc or drum granulation, and need to dry coarse powder or irregular small pieces of organic fertilizer (moisture <15%) and pulverize it into very fine (more than 100 mesh) powder , and then add binder and inorganic fertilizer, and the amount of binder and inorganic fertilizer added in the organic fertilizer cannot be greater than 30%. Although this method can be made into spherical particles, because the organic fertilizer in the processing process will be first Sufficient precipitation is crushed, water is added to granulate and then dried, repeated many times, so the organic fertilizer processing cost is quite high, and due to the low density of organic fertilizer, the particle strength is low, which is not conducive to storage, transportation and machine sowing.
  • There are also some manufacturers who first dry the coarse powder or irregular small pieces of organic fertilizer to a moisture content of only 20-25%, and then use a flat die extrusion granulator or a counter-roll extrusion granulator to dry the fertilizer. The organic fertilizer is extruded into columnar or flat spherical particles. Although this method is more convenient to use, the fluidity is not very good, it is not suitable for machine sowing, and the appearance is poor and the appearance is not good.

  • There are also some manufacturers who extrude coarse powder or irregular small pieces of organic fertilizer into short columnar particles with a flat die extrusion pelletizer(due to high moisture and high fiber content, the columnar particles also have certain characteristics. Plasticity), then polished and formed into spherical particles, and then the spherical particles are dried, cooled and screened to obtain qualified particles. In this method, the raw materials do not need to be treated, the order of moisture is reduced, and the production cost is greatly reduced, but this method also has some fatal The weakness is that the organic fertilizer is easy to be arched, easy to block and easy to bond equipment, and at the same time, the output is small and the power consumption of the extrusion process is high.

Therefore, in summary, the use of collision granulator to produce organic granular fertilizer has the advantages of low production cost, uniform product particle size, high strength, good fluidity, favorable for long-term storage and transportation, and suitable for machine sowing. That is to say, the performance of the products produced in this way is very good.

Classification and Difference of Organic Fertilizer Granulator

The organic fertilizer granulator is the main mechanical facility for granulating the fermented organic fertilizer. There are also a wide variety of organic fertilizer granulators. The well-known ones are extrusion granulators, disc granulators, drum granulators, roller extrusion granulators, flat film granulators, and so on. So how do we distinguish them in our work?

Rotary Drum Fertilizer Granulating Machine

The drum granulator is suitable for organic and inorganic materials. In addition, the equipment is easy to operate, flexible in work, and convenient to maintain.

The disc granulator relies on water spray to granulate, because the granulation rate can reach more than 93%. The pelletizing tray is equipped with three discharge ports, which is convenient for intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

The particles of the extrusion granulator can be directly bagged. The extrusion granulator is also suitable for metallurgical material particles, refractory material particles, and mineral powder particles. There is no need to add drying equipment when designing an organic fertilizer production line. The investment of the extrusion granulator is small, and the effect is quick, with an annual output of 10,000 to 100,000 tons.

The roller extrusion granulator is a granulating equipment. It is produced by the non-drying process, one-time molding, and the output is 1-1.5 tons/hour and 1.5-3 tons/hour. The organic fertilizer granulator has low investment, quick effect and good economic benefits.

Although there are many types of organic fertilizer granulators, each has its own unique function, and the output will increase if combined with supporting production. After everyone understands these differences, there should be some changes in the use of organic fertilizer granulators.

Introduction of Granulation Process of Organic Fertilizer Production Line

In a whole set of organic fertilizer production line, granulation is a key process in the whole production process. The productivity of the organic fertilizer granulator, the strength and shape of the granules produced directly affect the quality of the product.

Rotary Drum Fertilizer Granulating Machine

Among the many organic fertilizer production enterprises, the most used organic fertilizer granulation equipment includes drum granulator, extrusion granulation machine and disk granulator machine. Among the three granulation methods, the disc granulator is more suitable for the granulation of organic-inorganic compound fertilizer, and the effect is more ideal. The disc granulator is mainly composed of granulation disc, spray system, transmission device, bracket and so on.

Pig Manure Granulation Machine

During production, the powder raw materials are conveyed by the belt conveyor to the granulation disc in the disc granulator, and the rotating disc with an inclination of 50° rotates the animal material. When the material is brought to a certain height, under the action of its own gravity and inertial force, it breaks away from the disc and slides down along the arc-shaped trajectory to complete the rolling required for granulation. At the same time, the liquid injected by the spray system will be evenly sprayed on the rolling materials to agglomerate them into granules, thus completing the entire granulation process. According to the principle applied in this granulation process, we can call it agglomerate granulation process. With the continuous addition of raw materials, the manufactured particles fall across the edge of the disk under the action of centrifugal force and fall into the belt conveying equipment below.

As an old model, the disc granulator has experienced the test of various materials, but any equipment has advantages and disadvantages. With the diversification of raw materials, organic fertilizer equipment manufacturers are constantly developing new granulation equipment. In the production of ordinary organic fertilizers, there is a new type fertilizer stirring tooth granulator, which has high production efficiency and good product quality. In terms of organic-inorganic compound fertilizer, there is also a new type compound fertilizer granulator, which is improved on the basis of the stirring tooth granulator, but it has solved the problem of material sticking to the wall. It’s also very beautiful. The diversification of raw materials has promoted the diversification of organic fertilizer granulation equipment. Only by purchasing equipment suitable for your own materials can the whole set of organic fertilizer equipment be effective.

The Characteristics of Drum Granulator and Disc Granulator

In the organic fertilizer production industry, there are many types of equipment that can make organic fertilizer, and there are different supporting equipment according to different materials. We use poultry manure as raw material to analyze the two different organic fertilizer production of drum granulator and disc granulator.

The advantages and disadvantages of each granulator.

Disc granulation process characteristics:

The operation is intuitive, and the operation of the equipment can be grasped at any time. If an abnormality is found, the size of the particles can be adjusted in time. It is determined by the inclination and rotation speed of the disc, and the inclination and rotation speed of the disc can be adjusted. The control range of the particle size is wide, the adaptability is strong, and the ball formation rate is very high, which can reach 70% to 90%. The livestock manure organic fertilizer disc granulation process has short production process, simple structure, low investment and easy operation, which is more suitable for small and medium-sized enterprises.

Characteristics of drum granulation process:

Steam is introduced into the material layer in the drum to increase the temperature of the granulated material, dissolve the salt of the granulated material, and achieve a high liquid phase volume under low moisture content to meet the liquid phase volume required for material granulation. At the same time, the amount of evaporated water in the drying process is reduced. The inner wall of the drum is lined with a number of soft rubber plates or polypropylene plates, and there are vent holes at the corresponding positions on the cylinder. When the inner lining turns from the bottom to the upper with the cylinder at the same time, the inner lining sags due to its own weight, thereby causing adhesion The material on the inner lining falls due to gravity to achieve the function of automatically cleaning the conglomerate. During the operation, the operator can observe the ball formation of the material at any time, and take corresponding measures in time as needed to ensure the normal operation of the system.

There are quality pan granulator and rotary drum granulator in FPC. Welcome to our website to buy granulation machines.
