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
