Batch Ball Mill for Open or Closed Circuit 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.

Votorantim Metais CBAs alumina refinery produces 0.9 Mtpa of SGA. Recently the particle size of the rod-ball mill product has suffered an increase of 35 in the 590 m fraction.

Increasing Extraction Efficiency Using a Closed Grinding

Increasing Extraction Efficiency Using a Closed Grinding

The solution studied was a Closed Grinding Circuit, which aims to control particle size by sieving the mill product at 590 m, returning the oversize to grinding. This improves digestion efficiency, since smaller particles react faster and suffer less shortcircuits.
