## Calculate a Mill's Operating Work Index 911 Metallurgist

14/03/2015 Calculate a Mill’s Operating Work Index. Use this online formula to calculate a Ball Mill, Rod Mill or SAG Mill Operating Work Index. Based on Fred Bond’s work you can estimate the energy used into your grinding circuit. This is the most accurate and informative method, but much of the data necessary for its application is not yet available.

Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2), which renders to the AG/SAG mill the credit for the fraction of the material that had been already ground to final product (Q1). To calculate the operating work indices, equations [5] and [6] must be solved. The equations contain three unknowns: 1. Q1: the Fines Factor, 2. Q2
