A cement mill (or finish mill in North American usage) 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.
Or Cement is often confused with concrete. Cement is a finely ground, usually grey colored mineral powder. When mixed with water, cement acts as a glue to bind together the sand, gravel and crushed stone to form concrete, one of the most durable and widely used construction materials in the world.
