WORKING PRINCIPLE The machine is a vertical axis reflection type grinder, which can complete two processing processes of micro crushing and particle sorting at the same time. The grinder is composed of a moving disk and a gear ring. Through the high-speed rotation of a special shape of the moving disk, it is squeezed, collided and cut for many times, so as to achieve crushing. The material receives impact and shear between the high-speed rotating rotor and the stator of the toothed lining. The crushed material enters the grading area driven by the air flow. The qualified material is collected by the cyclone and dust collector, and the unqualified material is returned to the crushing area for crushing. CHARACTERISTICS ● The machine has compact and reasonable structure, small size, low energy consumption, high efficiency, stable speed, low noise, reliable sealing, no dust pollution, simple installation, easy disassembly and repair, convenient replacem…
