A 10 MW cement mill, output 270 tonnes per hour. 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.China O-Sepa cement mill separator supplier offers O-Sepa cement mill separator, max capacity 180-300 T/H, air volume 500-5000 M3/H, max feeding 75-750 T/H.
