In dry grinding, material is transported through the mill by medium-high velocity air that is injected at the inlet or mill feed end. As the mill rotates, mineral critical size fines are brought to the ball charge surface and are suspended and liberated by the injected air velocity currents and swept out the exit port.

Firstly, the raw material is put into feed silo, from which raw material is transported to the ball mill through vibrating feeding device. In the ball mill, with the impact of media balls, these raw materials are ground to fine calcium carbonate powder. And then the materials from the ball mill will be blown through classifier.
