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 . The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles,
