Working principle of environmental protection type double roller granulator
The double roller granulator is produced by non drying and normal temperature process. It has two kinds of specifications with one-time forming and large output. The double roller granulator has less investment and good economic benefit. A complete set of environmental protection type of roller granulator equipment layout compact, scientific and reasonable, advanced technology. Energy saving, no waste discharge, stable operation, reliable operation and convenient maintenance. The fertilizer granulation machine is suitable for granulation of coal powder, compound fertilizer, medicine, chemical industry, feed and other raw materials with high granulation rate.
The working principle of the double roller granulator is very simple. It has four functions
1. In order to ensure the continuous feeding of the equipment during extrusion granulation, the screw conveyor and vibration conveyor are generally used as the feeding equipment;
2. Then there is the forced feeding system, which is to control the feeding speed. It seems that the feeding speed is uniform, which can increase the feeding quantity and output. Its function is to degass in advance and apply pressure in advance, so as to improve the product quality;
3. Double shaft output is used for roll extrusion of the organic fertilizer granulation machine, which can effectively improve the speed of transportation, protect the bearing capacity of the main shaft, reduce damage, and improve the transmission effect. The hydraulic cylinder has stable pressure, so that the floating roll can run smoothly.
4. Granulation: the material sent by the conveyor driven by the motor is broken by the chopping system, and then the powdery material is evenly added into the binding sheet to shake, and then enters into the roll mouth after forced degassing and preloading. According to the specification requirements of the particles, with the rotation of the counter roll, it gradually achieves the molding. Then the automatic demoulding process is completed.
