o Finished grinding may consume 25 50 kWh/t cement, depending on the feed material grindability, additives used, plant design especially the required cement fineness. Cement grinding is the single biggest consumer of electricity in the manufacturing process. Whichever the mill types, grinding is inherently inefficient

This gives good cement performance, and reduces energy consumption by 2040% compared with a standard ball mill system. Capacity of cement mills. The cement mills on a cement plant are usually sized for a clinker consumption considerably greater than the output of the plant's kilns. This is for two reasons:

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.
