A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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 circuit consists of a two compartment ball mill and a dynamic air classifier. There is a slotted diaphragm inside the ball mill that separates the two chambers from each other. The particles coarser than the size of the slots (10 mm) stay in the first chamber while the finer particles pass the second chamber for further size reduction.
