Working Principle The material shol』Id not exceed Mohs hardness 3 The two grinding discs rotate at high speed in opposite directions. The fine” ness of the pr duct can be adjusted by the speed of the grinding disc. It can be cleaned easily by opening the grinding disc. Suitable f。『 grinding materials with Mohs ha 『dness below 3. No screen, smooth discharging, high productivity, I w perating cost. Double drive can be used to achieve a line speed ab ve 200m/s to obtain a better grinding effect.
