Ball Mill Design/Power Calculation
The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

The four major costs associated with cement production
The power requirement of cement plants varies in accordance with the heat treatment process used viz., dry process or wet process. While the wet process requires almost 1,300-1,600 kcal/kg of clinker and 110-115 kwh of power to manufacture 1 tonne of cement, the dry process requires 720-990 kcal/kg of clinker and 95-110 kwh of power.
