A grinder is a grinder that grinds the surface of a workpiece with a lap that is coated or embedded with abrasive. Principle: The raw material is added by the natural hopper composed of the middle and the rear two rolls and two baffles. After the reverse rotation of the middle and rear sets, the raw materials are sharply turned, sheared, and the structural stress surface between the raw material molecules is broken. Through the secondary grinding of the medium and front continuous rolls at high speed, the high-speed uniform mixing of various raw materials is achieved.
