(sliding, surging, slumping, rolling, cascading, cataract-ing and centrifuging), which depend on the rotation speed, degree of lling of the drum, physical properties of the material and geometry of the cylindrical part (Mellmann 2001). Since the diameter of the mineral material must be reduced by the grinding process in the ball mills, it is nec-
than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major part of the cement production with newly installed mills comes from ...

There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:
