4 Examples of the Efficiency Formula - SimplicableMachine efficiency can be measured in terms of energy efficiency or the productive results of equipment. The latter approach uses the value of outputs and cost of inputs. In a month, a drilling machine takes inputs such as labor, electricity, materials .CALCULATION OF THE POWER DRAW OF DRY MULTI–COMPARTMENT BALL .of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous andJMEThe average efficiency of the initial ball mill was obtained which was equal to 72.96%. The average of the proportion of (consumed) energy by SAG and ball mills from total consumed energy at mills, was 44.65% and 55.35% respectively. ...(PDF) Effect of circulating load and classification .Effect of circulating load and classification efficiency on HPGR and ball mill capacityA Method of C alculating Autogenous/ Semi-Autogenous Grinding Mill .mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being ﬁ ﬁ ner than 650 μm. These ﬁ nes proceed to the ball mill improving the ball mill efﬁ ciency.
