Comparative Bond Ball Mill Work Index. A bond ball mill work index test is a standard test for determining the ball mill work index of a sample of ore it was developed by fred bond in 1952 and modified in 1961 jkmrc co 2006 this index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy required 1.Introduction.A bond ball mill work index test is a standard test for determining the ball mill work index of a sample of ore.It was developed by fred bond in 1952 and modified in 1961 jkmrc co., 2006.This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill. Similar to a Comparative Work Index, this test is an open circuit dry batch grindability test run in the standard Bond Ball Mill for a set time. It can be used at mesh sizes from 65 to 200 mesh (normally 100 mesh). The test requires calibration against the standard Bond Ball Mill . Modified Or Comparative Bond Ball Mill.
