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.

For fine grinding, the charge consist of small balls, which ensure the best possible grinding efficiency without obstructing the material flow through the ball charge. Special designed diaphagm between the grinding compartments effectively screens the material passing from the coarse to the fine grinding compartment.

The stress intensity expressed as the power input per ball is dependent on the ball diameter to the third power and only slightly dependent on the inner diameter of the mill. The number of stresses can be characterised by the average retention time of the ground material inside the mill if the ball charge grading remains unchanged.
