Cement Grinding
Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding are generally found in cement plants for cement

Cement mill
Cement milling is the largest user of electric power on a cement plant, and because they can easily be started and stopped, it often pays to operate cement mills only during "off-peak" periods when cheaper power is available. This is also favourable for electricity producers, who can negotiate power prices with major users in order to balance their generating capacity over 24 hours. More

Identify and resolve mill ventilation problems in cement plants | GCP
Identifying and resolving mill ventilation shortfalls. There is a common misunderstanding that to make a finer cement you should reduce the mill ventilation to keep the cement in the mill longer. In fact, this simply leads to over-grinding and increased void filling, which reduces grinding efficiency and often leads to a wider particle side

CEMENT PLANT TALK-001
Cement Mill Common Issue: Higher cement temperature, Mill tripping under high cement temperature or mill outlet temperature is not an uncommon in cement mills. It happens in majority of cases due to high clinker temperature and the other reasons could be insufficient mill venting and insufficient or faulty water spray system.

How to Deal with the High Temperature Problem of Cement Mill | Studymode
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 which are more effective than ball mills. Cement mill is not only suitable for over-flow grinding, but applicable for cyclic closed-flow grinding together with powder collector. We all
