The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling

Fine Grinding Technology for Mines and Concentrating . Ball mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns Below 30 microns the advantages of a horizontal stirred mill become dramatic and below a certain point the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption
Feb 01, 2021 · Assumption mill power for rated power 3200KW, the use of ceramic ball Q₁= 145T /h before grinding host unit power consumption is 3200/145=22.1kWh/t, switch to ceramic ball after power reduction 25%, 3200-3200×25%= 2400KW,Q₂= 121T /h when grinding host unit power consumption is 2400/121=19.84kWh/t, if the station does not reduce 2400/145=16.55kWh/t
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption
