Jul 31, 2014· Table 1. Bond method power calculation for two-compartment mill Mill feed F80 (mm) EF4 Power required (kW) Difference (%) 15.5 1.06 3564 0.0 4.5 1.01 3251 8.8 3.0 1 3133 12.1 1.8 1 3018 15.3 It can be seen that a reduction in two-compartment mill power in the order of 9–15% is calculated for different crushed clinker feed F80 sizes.

Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites.
