In modern cement mills, a microprocessor-based control scheme is used. 2. Mill Drives: Requirements of mill drives are: High starting torque. The starting current must be limited to a maximum of two times the full load value to minimize voltage dips. An overload capacity of 50% for 1 min occurring for 4 times an hour.

Function: A cement mill is a drive 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. Process: Raw materials are fed to the mill in right proportion with the help of weighfeeders.
