2021-1-18 Crushing and classification refer to operations that reduce the particle size of mineral raw materials and have certain particle size distribution characteristics through certain mechanical equipment. Generally, the operation of reducing the particle size to 20-5mm is called crushing, and the corresponding equipment is a crusher; the finer crushing operation is called grinding, and the corresponding equipment is a grinding machine; it is matched with the crusher and the grinding machine
