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

A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits. Sample Requirements A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm as required for the Bond Ball Mill Work Index test feed.
