Calculation of energy required for grinding in a ball mill ...
198911 The grindingproduct size, P, in a Bond ball mill, which is given by the aperture size which passes 80% of the grinding product as a function of the aperture size of the test screen Pk, Can be expressed by the formula P=Pk/K2. These functions for G and P enable us to calculate the value of Wi for any other size of grinding product if we know ...

The Evolution of Grinding Mill Power Models SpringerLink
2019130 Mill power models have been used in a variety of ways in industrial practice since power directly equates to throughput and fineness of ground product. We first start with HoggFuerstenau Power Model and show how this model successfully predicted the power draw of many grinding mills in several mining operations. Then, we show how this model was on the verge of being able to predict the ...
