A cement mill 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 Heat generated in the grinding process causes gypsum (CaSO4.2H2O) to lose water, forming bassanite

A feeder with draws clinkers from the hopper and sends them to the pre-grinding crusher, a vertical roll mill, where the clinkers are preliminarily crushed. The coarser powders are sent back to the pre-grinding mill. The finer powders are fed into the ball mill with gypsum for futher grinding to produce finished cement product.
