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.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

The aim of this theoretical study is to better understand the complex interplay between ball milling and air classification in full-scale two-compartment ball mills for cement clinker milling. To this end, we modified the true unsteady-state simulator (TUSSIM) for a full-scale open-circuit cement ball mill [4] by coupling the PBM for the …

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

Cement ball mill is a well known machine to grind raw material (hard clinker) into grey powder: Cement. A cement ball mill is a horizontal cylinder which is partly filled with steel balls of different sizes along with clinker (raw material) and rotates about its axis which provides tumbling action in ball mill which in turn grind raw material …
