How it works
The feeding system feeds the materials evenly into the grinding chamber, exposing them to strong impacts from the high-speed rotating grinding discs. The materials are subjected to various forces, including friction, shearing, and collision between the static disc and gear ring, which leads to the grinding—depending on the properties of different materials, choosing from varying combinations of both discs so that it meets specific requirements for other materials.
