At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 µm
Jan 01, 2012 · A simplified procedure is proposed to calculate the Bond rod mill work index. It accounts for the accelerated breakage rates of coarse particle in the rod mill. It uses about 1/5th of the sample volume when compared to the standard test. It is based on simulation of the test from data collected in batch tests. It predicted the Bond rod mill work index with less than 1 kWh/t and 10% of deviation in …
