Variables Affecting Grinding Mill Power

2021-1-18 · The study of grinding is a study of cause and effect. The pre-ponderance of the literature is on the latter—effect. It seems that the study began at the end, with effect, and worked backward without going back far enough to reach the cause. The cause is energy input. In this paper it is paramount and is expressed as horsepower. Power is one of the most enlightening single factors in the ...
