Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.

The closed circuit grinding system, all ground materials are led into a separator and classified into refined powder (products) and coarse powder (return powder). The coarse powder is returned to the ball mill and ground again with newly fed raw materials. Following benefits can be realized with this technology Grinding capacity increases;

Closed circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
