Ball mill  Wikipedia
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

The cement mill
Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.

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.
