2009-8-1 Grinding of clinker for cement production is often performed in a two chamber ball mill. In the first shorter chamber, raw feed is ground using media consisting of large balls. Recently, the effect of feed size in the first chamber has been investigated using DEM for a cement mill (Cleary et al., 2008). The ground product of the first chamber then exits through a discharge grate and enters the longer second chamber.

Calculate and Select Ball Mill Ball Size for Optimum Grinding
2013-8-2 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
