A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Overview. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
Cement grinding. The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).
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.
