## Crushing work index Calculation Crushing, Screening

2021-8-21 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.
