Maxson et al, (1933). It was extended by Bond (1952) to provide a work index result that was empirically calibrated to make a laboratory work index match the corresponding work index measured in an industrial grinding mill. The fitted equation, in metric form, is given as Equation (1). (1) 𝑊𝑖= 1.1023×44.5 𝑃100 0.23× À0.82×(10 √ ...
The work index Wi can be determined from plant operations and from laboratory ball mill grindability, rod mill grindability, and impact crushing tests. The laboratory test results are used to check the efficiency of commercial operations and to compute the proper machine sizes for new installations.
