Cement mill Wikipedia

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.

Cement Extraction, Processing, Manufacturing | Britannica

The clinker and the required amount of gypsum are ground to a fine powder in horizontal mills similar to those used for grinding the raw materials. The material may pass straight through the mill (opencircuit grinding), or coarser material may be separated from the ground product and returned to the mill for further grinding (closedcircuit ...

Cement grinding Vertical roller mills VS ball mills

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.
