Mills are used for grinding raw material i.e. ball mill and vertical roller mill (VRM). The VRM combines the drying, grinding and separation processes into just one unit. In VRM, raw material from the feed mouth fells into the center of millstone, which moved to the edge of mill under the action of centrifugal force and is ground by
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.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
