Optimization of Cement Grinding Operation in Ball Mills ...
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.

Factors Affecting Ball Mill Grinding Efficiency
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.

ing chamber, which maximizes grinding efficiency. The cyclone underflow pump 6, which is installed upstream of the mill, ensures a steady and proper flow through the grinding chamber. Once the coarse particles have been reduced in size, they are carried by the upward slurry movement to the mill chamber's overflow outlet flange 7.
