The Sum Of Crushing Energy And Grinding Energy

This measure suggests that a VSI can save 214 of the energy consumed in grinding depending on the energy model used and the final product size This estimate is in agreement with an energy saving of 118 observed in an iron ore application where VSIs were introduced as a crushing step preceding the grinding circuit
