Get QuoteThe batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material. Different from continuous ball mill, batch type ball mill grinds powder by times and adopts intermittent operation. The batch mill is mainly used for the mixing and grinding of materials, with uniform product fineness and saving power.
Get QuoteTherefore, the rod mill has the ability to control the particle size and can be used as an open-circuit grinding equipment. Although the ball mill does not have the ability to control the particle size itself, it can control the particle size with the help of the classifying equipment. The mill will discharge ore into the classifying equipment.
