اقرأ أكثرDiagram of cement ball mill. (Based on an image from ThyssenKrupp AG. 15) Much of the energy consumed by a ball mill generates heat. Water is injected into the second chamber of the mill to provide evaporative cooling. Air flow through the mill is one medium for cement transport but also removes water vapour and makes some contribution to cooling.
