The machine consists of a crushing host, a cyclone collection mechanism, and a complete set of electrical appliances. The host consists of a frame, a main motor, a feeding mechanism, an adjusting mechanism, and a pair of moving and fixed grinding discs. The basic principle is to achieve the purpose of crushing by shearing and grinding the material through the relative motion of two grinding discs. Using air and water cooling to control the crushing temperature and improve the quality of the powdered material. The feeding mechanism adopts infinite variable speed, which can adjust the corresponding feeding speed according to different materials to meet the requirements of the product.
