As one of leaders of basic concept of cement ball mill particle size distribution industry, SBM always seeks innovation & excellence.
However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system. Capacity of cement mills

In 1904, Krupp produced a self-contained cement mill using a ball mill and their version of the Askham separator in closed circuit, but I think this was never used in Britain. However, from the mid 1890s, ball mills were used in combination with tube mills (see below) and this setup became the normal cement milling installation until 1920.

Ball Size vs. Grindability. It has been recognized that the grindability of an ore in a ball mill is a function of both feed and mill parameters: Work index, W i; Largest particle size and size distribution; Density of solids and slurry; Mill diameter; Rotational speed; Rowland and Kjos (1980) defined the largest ball size needed based on these ...

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.
