The development of ball mill equipment is closely related with technology progress of humankind and the overall industrial level, especially with the development of the science of mechanical engineering and mining disciplines. Ball mill is the key milling equipment after material has been crushed. It is widely used in cement, silicate, new construction material, refractory material, chemical fertilizer, ferrous metal and non-ferrous metal as well as ceramics. It is widely applied to dry or wet grinding for ores and other materials. Ball mill is the key equipment for grinding after the crush process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, also it can be used for the dry and wet grinding for all kinds of Owers and other grind-able materials. Overflow Ball Mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material being continuously recirculated back into the mill to be reduced. Various classifier5.html > classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. Ball mill is an efficient tool for grinding many materials into fine powder. In production, the concentration of the discharging grade ball mill is higher than the one, for the former overflow has the forcedly discharging function. If the concentration is dilutes, the flow rate speeds up, impact times between the particles and the grinding medium decrease, all those will not only reduce the grinding efficiency but also speed up the abrasion of the liner and the steel ball, meanwhile the coexistence tends to become coarse (known as running coarse). Chinaware ball mill is mainly used for mixing, milling of the pipes.
