Jan 01, 1989 INTRODUCTION The energy consumption for grinding, according to Bond (1961), is deter- mined by the formula 10 10 (I) The work index is determined by grinding experiments carried out in a labo- ratory Bond ball mill. Based on the results of grinding experiments, numerical values of the work index Wi are calculated according to the formula 0301-7516 89 $03.50 1989 Elsevier Science.
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.
