Working Principle

It's mainly composed of three sets of grinding heads, clutch, mortar support, localizer, etc.

Grinding head, mortar support and clutch are evenly installed on the rotating seat and in the bearing of rotating seat, at an angle of 120° between each two of them. On the front of the base are mounted receiving support plate and electrical equipment; on its left is installed a motor. When the clutches are connected, the motor drives the rotation of the grinding head through the belt pulley, gear shaft, and cardan joint. The other end of gear shaft and the gear of mortar supportengage. Since relative sliding occurs due to clockwise rotation of grinding bar and clockwise rotation of mortar, the materials are grinded through the weight of grinding head.
