Bond equation of cement ball mill sizing - CHAENG
Efficiency correction factors are applied with the Bond equation. The method is valid both for clinker grinding and for materials grinding. This method only gives a rough and initial idea for sizing a cement ball mill. To go ahead a deeper study is necessary with ball mills suppliers or a specialized engineering office.
