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 chamberBall mill operation is often regarded as something of a mystery for several reasons Ball milling is not an art it’s just physics The first problem will ball mills is that we cannot see what is occurring in the mill The other problem is that many of the independent variables are non linear or have paradoxical effects on the end results
