Unit 8. 2 Industrial Drives. Prasad Assistant Professor EEE Dept. E Mail: Mobile No:+91 • 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.
