Energy Benchmarking

The Morrell Method for grinding mills is based on predicting the specific energy at the pinion shaft. To adjust the power draw measured at the motor input to power at the pinion a 6.5% correction was made. In the case of crushers the Morrell Method relates to motor input power less no-load power (net power).
