cement material temperature control in cement ball mills

Acementmill(or finishmillinNorth American usage) is the equipment used to grind the hard, nodular clinker from thecementkiln into the fine grey powder that iscement.Mostcementis currently ground inballmillsand also vertical rollermillswhich are more effective thanballmills.
