The disc granulator can be used for various dry powder granulation and wet granulation of dry powder. Wet granulation has a good effect and should be prioritized. It is the main equipment for pelletizing powder materials, with advantages such as uniform pelletizing, easy control of water content in the pellets, high strength of the pellets, simple structure, convenient control, low power consumption, and smooth operation.
Principle of disc granulator: Various dry powder materials are added from the top of the equipment, degassed, spiral pre compressed, and transported to the curved grooves of two rollers. The two rollers rotate at equal speed and in reverse direction, biting the materials into the grooves and performing forced compression. The pressure the materials bear after passing through the compression zone gradually decreases, and their surface tension and gravity cause them to naturally come out. They enter the crusher and granulator for crushing and trimming, and then enter the vibrating screen for screening, Qualified products are sent to the finished product warehouse or directly packaged through a conveyor, and the powder screened materials are sent back to the raw material warehouse for secondary rolling through a feeding device. The size of the extrusion pressure can be adjusted by the hydraulic system according to the particle strength needs. By changing the groove form of the roller surface, materials such as flakes, strips, olives, and flat balls can be obtained.
The structure composition of the cow and sheep manure organic fertilizer disc granulator: The cow and sheep manure organic fertilizer disc granulator is composed of a ball forming disc, a bridge device, a motor, a reducer, a frame, a scraper device, etc.
Performance characteristics of the pan granulator for cow and sheep manure organic fertilizer:
- The bottom of the ball forming disc is reinforced with multiple radiating steel plates, which have high strength and stiffness;
- The transmission gear adopts high-frequency quenching treatment, with a long service life;
- The reducer and motor are driven by flexible belts, ensuring smooth starting and low impact force;
- The transmission system has added a bridge device to reduce the direct impact of gears and reducers, improving the stability of equipment operation while also improving the service life of main components; 5. Adopting a unique unpowered combination scraper device, the auxiliary power consumption is reduced.
