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,

The knife ground sample was used in order to facilitate the grinding process in cryogenic or ball mill. Cryogenic grinding was performed in a cryogenic mill (Spex model 6800, USA) with a selfcontainer liquid nitrogen bath. The precooling time was 5 min and grinding times were in the range from 10 to 50 min (525 cycles of 2 min grinding).

Lab rod mills tend to produce a particle and mineral P80 of similar size (can vary when high levels of mica or similar), but the plant closed circuit mill with a hydroclone can give finer grind size of the heavier minerals. This ultimately might mean that that the plant grind size can be coarser than the lab grind size.
