BothCrushing work index Calculation - Crushing, Screening,,As Alex told you: The crushing work index you calculated appears mostly correct. The only correction factor that might affect the calculation is to correct for the efficiency of the motor -- the work index is based on motor output (pinion) power, whereas the measurement of motor power is usually based on motor input power. I have attached a calculation of operating work index that includes the motorTestwork: Bond crushing work index - SAGMILLING.COM,Modelling. Crushing mill work index is used in the SAGMILLING.COM Bond/Barratt specific energy consumption model .
