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. 2 Materials ground. 3 Temperature control.
Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
View MoreDue to limitation of the mills rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills Pilevneli and Azizli, 1999 indicates that using smaller media 58 mm range improves grinding energy efficiency up to 50 using stirred mills.

View MoreOperation 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.
View MoreThe use of highpressure grinding rolls HPGR prior to ball mills has become a common practice in cement clinker grinding due to significant energy savings in comparison to ball milling alone.
