    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
