In Cement Industry raw meal blending or homogenization is always done in silos. It is the last homogenizing step in the line of the raw mix preparation processes installed with the aim to reduce the residual (relatively short-term, high frequent) compositional variations observed for the raw meal produced in the raw mill.
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.

In the whole process of cement production, the electricity consumption of a raw material mill accounts for about 24% of the total. Based on the statistics of the electricity consumption of the raw material mill system of 1005 production lines in China between 2014 and 2019, it is found that the average electricity consumption of the raw …
The "work horse" of the cement grinding plant is the two-compartment ball mill, commonly called the tube mill. Significant advances in model development were achieved in recent years (Benzer et al., 2001, Benzer et al., 2003) through research on industrial scale. The breakage and transport mechanisms are better understood as well …
