The purpose of cement milling is to achieve a specific particle size distribution (PSD) that allows the cement to have the desired physical properties. The PSD is crucial because it influences the strength, setting time, and workability of the cement. The milling process achieves the desired PSD by grinding the clinker and other raw materials ...

In the case of a laboratory ball mill for cement clinker milling, the mill dimensions and operation data were taken from [33]. The ball mill's diameter D T was 0.2 m, and the length L T was 0.2 m. Ball filling fraction J T was 0.2, and void filling fraction U T was 0.525. The ball mill rotated at a fractional speed ϕ C,T of 0.75.

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.
