The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed .
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.
In order to reduce it, greater than normal velocity must be applied. When the speed exceeds 250 fps (75 mps) the result is high inter-particle compression and forceful attrition which achieves a milling effect. REMco Vertical Shaft Grinder - VSG units operate well above crushing speeds and mill with velocities up to 360 fps (110 mps).
a unique patented design concept that includes a new grinding tank internal configuration and side discharge screen which allows mills to run at higher speed, using smaller media, and continuously discharges products out of the mill by centrifugal force. (Fig. 6) HSA Attritors generally operate from 400-1800 RPM using grinding beads from 1-3mm.

One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the harder to grind material in the mill.
