Specific power consumption depends upon material hardness and mill efficiency. For ball mills, the range is approximately 8kWht mill drive Cement Plant Operations Handbook 15 29. only for soft, chalky limestone to 25kWht for hard materials.
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 is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed

Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarsegrinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
Operation. Material grinding process motor through reducer rotating drive disc, the material falls from the mill under the central entrance and exit, under the action of centrifugal force to the disc edge by the roller to move and the crushing, grinding out lap after the material was speed up the flow to and vertical mill with one of the separator, after the meal by the separator back to the
