Grinding Mills and Their Types – IspatGuru
The milling circuit is the complete mill system from beginning to end, which includes feed mechanism, mill, classifier, separator, product collector, etc. In a closed mill circuit, the oversize particles are returned from the post milling processes to be regrinding, while in an open circuit the process there is no feedback loop.

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.
