Controlling the rotary drum granulator to improve the particle roundness

The time and frequency of material rolling in the rotary drum granulator are the primary factors to determine the pelletizing rate and particle roundness. The roundness of granular product in fertilizer production line can be improved by controlling the drum granulator.

Production principle of rotary drum granulator

Materials rely on surface tension, proper amount of liquid phase, extrusion force generated by rolling between materials, and correct movement direction of materials in the granulator, with small particles as the core, they absorb and adhere to each other and form balls in rolling. In a certain period of time, the higher the rolling frequency is, the higher the spheroidization rate is, and the rounder the particles are.

In the process of production, we have encountered two kinds of situations due to the different friction between materials and the wall of granulator.
1. The internal surface finish of granulator is large, so that the friction force between material and cylinder wall is reduced, and the upward movement force of material is weakened. If the material does not roll, it will not produce particles. In view of this situation, we can solve this problem by adjusting the speed of the granulator and installing a small plate inside.
2. The material in the drum granulator is severely stuck to the wall, and the friction between the material in the granulator and the wall of the barrel is increased, which raises the material in the machine too high, causing the material to fall from the top, so that the formed particles are not Rounding and excessive large particles, we think there are two reasons for this situation: on the one hand, the material is caused by too much viscous material, in this case, we change the formula of the npk production line to reduce the amount of viscous material; on the other hand , The inside of the granulator is not smooth. In this case, we change the internal material to increase the smoothness of the granulator.

On the other hand, we should also control the reasonable amount of material returned to the whole fertilizer production line. The process of rotary drum steam granulation is different from that of general fertilizer granulator, the relative pelletizing rate is lower, and the amount of returned material is higher. The amount of returned material directly affects the output and quality. The product has less particles, more powder and larger amount of return material, which directly affects the output. Large particles return more materials, directly affect the smoothness and roundness of the product.

Several basic granulation methods of NPK fertilizer

Mixing granulation of different NPK fertilizers is the core of compound fertilizer processing. Fertilizer production line generally uses the following methods to granulate:

1. Extrusion granulation is a method of making dry powder or wet powder containing binder into cylindrical, spherical or sheet shape by mechanical processing such as extrusion, roller extrusion or pressing. The technology of dry granulation is used in the flat die pellet mill, the ring die pelleting machine and the double roller granulator.

2. Agglomerating granulation, which is under the action of rotation, vibration, agitation and so on, makes the wet powder in motion agglomerate. Or use the fluidized bed to make the material obtain the cohesive force by supplying the spray liquid binder) so as to grow into the appropriate particles. This method is used in disc granulator and rotary drum granulator.

3. Crushing granulation, which is to crush the block material into particles of appropriate size.

4. Melt granulation, which is a method of cooling and hardening molten liquid for granulation.

5. Spray granulation. It is a method of directly forming granules after concentrating the solid in the liquid.

6. The method of crystallization and granulation in liquid phase is to make materials precipitate and crystallize in liquid phase, at the same time, agglomerate into spherical particles by the action of liquid bridging agent and agitation. This technology is widely used in pharmaceutical industry. Because the shape of the particles is spherical, it is also called spherulite granulation, which is called spherulite granulation for short. Spherulite is a kind of spherical particle formed by the crystallization and aggregation of pure materials. It has good fluidity, filling and compression formability. In recent years, the technology has been successfully applied to functional pellets.

2. Operation method:

Mix all as required. Stack the material strips into piles, with a height of about 1.2m, unlimited length and ambient temperature. When the temperature of the pile rises to 45 ℃, the pile shall be turned over once every three days. If the temperature of the pile exceeds 65 ℃, it shall be turned over once every two days.
Signs of maturity: the temperature of the material is reduced, the material is loose, there is no original odor of the material, there is a slight smell of ammonia, and the pile is covered with white mycelium.
Compost stacking: it can be directly used after stacking and fermentation, or it can be used as the main material. Fertilizer granulator will process it into commercial organic fertilizer, bio organic fertilizer, organic-inorganic compound fertilizer, bio organic-inorganic compound fertilizer, etc.

Advantages of sugar residue organic fertilizer

High fertilizer efficiency and convenient application. Due to the fermentation period of only 7-15 days, the nutrients in the sugar residue are retained as much as possible; and due to the decomposition of microorganisms, some substances that are difficult to be absorbed and utilized by crops are rapidly transformed into effective nutrients. After fertilization, it can give full play to the fertilizer effect in a short time, quickly supplement the nutrients needed for crop growth, and maintain the fertilizer effect for a long time. The rotten filter mud is odorless, dry and loose, and easy to spread.

The organic fertilizer should not be mixed with strong acid, strong alkali, volatile chemicals and fungicides. Huaqiang factory provides a complete set of organic fertilizer equipment, and designs fertilizer production line for customers free of charge.
