Batch Ball Mill for Open or Closed Circuit Grinding

The 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.
