Cement Mill Overview. A cement mill is the equipment that 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. Cement clinker is usually ground using a cement ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls.
Kohat Cement Company Ltd has recently ordered as many as four vertical roller mills (VRM) from Loesche to expand its cement plant in Kohat, 160km west of the capital city of Islamabad, Pakistan. The order comprises a four-roller raw material mill with a material throughput of 500tph and two cement mills each with a grinding capacity of 210tph of Portland cement.
Cement Ball Mill. 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).
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.

The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
efficient vertical roller mills (VRMs) led to their replacement. Initially, this focused on grinding coal and the cement raw materials, with the adoption of vertical roller mills for cement product grinding – with its finer grinding requirements – com-ing more recently, in the late 1990s. The main reason for
A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...
