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.
The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 40-45%. If it is a grate discharge you will have more flexibility of the total charge. Ball size and ball grade is determined by the feed ore size and hardness, plus the PH level of the slurry.

Stresses, generated in the ball charge, increase, which may result in spalling of balls and blocking the grate discharge. Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator.
Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams coarse and fines. The coarse fraction is sent back to the mill and the fines are collected in cyclones and or a baghouse as finished product.
