The primary ball charge pattern and the design ball charge pattern that is introduced by KHD Company (Cement ball mill's manufacture Company) are presented in Table 6. It can be observed in this table that the amount of current ball charge is about 14% less than the amount of design ball charge, so it could reduce the CBM's efficiency.
Optimization of cement grinding using standard bond grinding calculations based on population balance models is successfully applied [4, 38]. Various grinding laws, energy relationships, control factors and controller design for cement grinding are discussed in [37]. Figure-1. Vertical roller mill for cement grinding [13].

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 ...
Vertical cement mills are able to reach production values which are significantly higher than the ones achievable with traditional ball mills, in some cases up to 300 t/h. Empirically, It can be estimated through a simple heat balance that in ball mills only 10% of the energy is used to
Vertical roller mills and ball mills represent two clearly distinct technologies. However, with proper adjustments to the operational parameters of the vertical roller mill almost identical cement properties can be achieved by the two mills that satisfy the cement user's demands.Nevertheless, the two types of mills have their distinctive merits.
