Vibration mill is a kind of ultra-fine grinding equipment with ball or rod as medium. Medium vibration in the mill can crush materials less than 2mm to several microns. It has the advantages of high efficiency, energy saving, space saving and uniform product particle size. It has important advantages in the field of ultra-fine grinding and has been widely used. The Palla tube type vibration mill developed in the 1970s in West Germany has entered more than 40 countries and regions around the world. From the ultra-fine grinding of industrial minerals and raw materials in the general metallurgy, building materials, non-metallic minerals, coal, chemical industry, light industry and other departments to the deep processing of new synthetic materials and magnetic materials, more than 100 kinds of materials have been processed. Classification According to the number of cylinders: single cylinder and multi cylinder; According to the excitation form, it can be divided into inertia type and eccentric rotation type; Grinding is divided into dry method and wet method according to whether water powder is added or not; According to the operation method, it is divided into intermittent type and continuous type.
