involves replacing the mill charge several times throughout the test. The Bond tests are typically run for a minimum of seven cycles, while the MacPherson and pilot plant tests are operated for about 610 hours. The achievement of steadystate is desirable in a grinding test, because harder components may build up over time. For AG/SAG mills,
