Calculation of energy required for grinding in a ball mill
The grinding-product 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= P k K 2. These functions for G and P enable us to calculate the value of Wi for any other size of grinding product if we know

Estimation of shear rates inside a ball millScienceDirect
Due to the complexity of charge motion inside a ball mill it is very difficult to calculate some mean shear rate accurately. Klimpel (1984) estimated the shear rates to range from 0 to 60 s −1 but no evidence was given as to how this figure was calculated.
