Organic fertilizer granulator is mainly used for coarse fiber granulation, such as: sawdust, rice husk, cotton stalk, cottonseed hull, weeds and other crop straw, domestic waste, factory waste and low adhesion rate, difficult to make material granulation. It can also be used for low temperature granulation of biological bacteria fertilizer, organic fertilizer and compound fertilizer.
The technology of disc granulator is introduced
1) The treated pig manure is directly transported to the raw material bin (or raw material mixer).
2) The pig manure is transported into the disc homogenizer and evenly added into the rotating disc of the disc granulator. Sprinkle the liquid component or appropriate amount of water through the liquid component distributor of the disc granulator. On the material in the disk, the amount of liquid phase needed to form the ball is satisfied; The rotating disk and the edge of the disk produce friction and centrifugal action on the material, which makes the material move in a circle, and the powder particles rub and knead each other. Extrude and gradually gather into clusters; Due to the different mass of particles, the gravity and centrifugal action are also different. When gravity and centrifugal force increase enough to overcome the friction between particles, they are thrown out of the disk. The smaller particles remain in the disk and continue to gather fine particles.
3) It is sent to the organic fertilizer dryer for heat exchange with the heat in the hot blast stove.
4) The fine particles are directly returned to the disc homogenizer, and continue to participate in the adhesion of particles to the ball as the core.
5) It is sent to the organic fertilizer cooler, and then the fertilizer is cooled with natural cooling air or strong cooling air.
6) The large particles are transported to the finished product screening machine, then crushed by the crusher, and then returned to the disc homogenizer to continue to participate in the formation of the ball.
7) The qualified products after screening are transported to the coating machine for coating treatment.
8) Transport to automatic packing scale for weighing, packing and storage.
9) After cyclone, labyrinth and wet scrubbing, dry, cool and workshop dust are discharged.
The production of organic fertilizer by disc granulation has the following advantages
The operation is intuitive, and the operation of the equipment can be mastered at any time. If any abnormality is found, it can be adjusted in time.
The particle size is determined by the tilt angle and rotation speed of the disk, and the tilt speed and rotation speed of the disk can be adjusted. Therefore, the disc granulation process has a wide range of particle size control, strong adaptability and high pelletizing rate, up to 70% - 90%.
The disc pelletizing process of organic fertilizer has the advantages of short production process, simple structure, less investment and simple operation, which is more suitable for small and medium-sized enterprises.
