Granulation mode and use method of roller granulator
The roller granulator mainly relies on the external pressure mode, so that the materials are forced to pass through the gap between the two opposite rotating rollers and compress into pieces. The formation process of granulation is through the formation of granulation nucleus, the growth of agglomerates and the spheroidization of particles, which makes the fine powder become particles with certain size and strength. After drying, it becomes granular material, also known as consolidation molding. The main transmission parts of the roller granulator are made of alloy, stainless steel, titanium, chromium and other surface alloys, which greatly improves the wear resistance, corrosion resistance, high temperature resistance and pressure resistance, so that the machine has a long service life.
Operation requirements of roller fertilizer granulator machine:
1. The speed of agitator and chopper can at least be changed by two speed motor, the speed range of agitator is 30 to 500, the speed range of chopper is 300 to 3000 rpm, the speed can be adjusted by frequency conversion, and the display can be set.
2. For the two speed simple control, the control has start, emergency stop, stop switch and fault display, as well as current display and speed change display of the second gear motor. When the discharge valve or drain is closed, the motor of mixing pulp and chopper can run, and vice versa. In addition, only when the discharge valve is closed can the cleaning process be started.
3. Electrical control should have self-protection function to prevent possible damage to dry granulator machine for fertilizer due to misoperation, including main motor fault protection and emergency stop protection. For configuration, it should be controlled by PL + Touch color LCD panel. The interface design is divided into manual trial operation interface and normal operation operation interface, and has good man-machine dialogue interface.
