The universal grinder is an universal equipment widely used in industries such as pharmaceuticals, chemicals, metallurgy, food, and construction, for processing hard and difficult grinding materials. Its core working principle involves the high-speed relative motion between the movable and fixed teeth discs. Through the combined effects of the impact and friction of the teeth, as well as the collisions between the materials, crushing is achieved. The final products can be directly discharged from the main machine's grinding chamber. The particle size can be adjusted by changing the mesh size of different screens, typically ranging from 10 to 120 mesh.
