The grinding roll promises to be a viable grinding machine of the future. Used as a primary mill in existent plants it can not only reduce energy consumption but also increase output.
A 10 MW cement mill output 270 tonnes per hour. A cement mill (or finish mill in North American usage 1 ) 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.
