Pin Mill

The material should not exceed Mohs hardness 3
  • The two needle discs in the mill rotate at high speed in opposite directions;
  • The fineness of the product is achieved by adjusting the speed of the dial;
  • The machine is easy to clean, just open the grinding door;
  • The material should not exceed Mohs hardness 3;
  • No sieve, smooth discharge, high capacity and low operation cost; dual power can be used to achieve a linear speed above 200m/s to obtain greater crushing power.

Working Principle

The materials are uniformly fed into the grinding chamber by the feeding system, and are strongly impacted by the high-speed rotating grinding movable disk. At the same time, they are subjected to various comprehensive forces such as friction, shearing, and collision between the static disk and the gear ring, so that the materials are crushed. According to the different properties of the materials, the grinding movable disk and the static disk can be combined with different structures to meet the crushing needs of different materials.
