The ball mill grindability test sometimes referred to as the Bond test was developed in the 1930s by the Allis Chalmers company to help them perform ore hardness characterisation testing to assist in industrial mill sizing Maxson et al, (1933). It was extended by Bond (1952) to provide a work index result that was empirically calibrated

One of the most important steps in conducting a locked-cycle test is deciding when the test is at steadystate. For Bond testing, test closure should include a maximum deviation from the highest and lowest Gpr (suggested value of 3%) and a reversaI in the rate of mill production during last three cycles (failure to reverse indicates instability).
