Generally, we need a very high reduction ratio to go from the run of mine to the liberation size. Therefore, it is necessary to divide the total R:1 into smaller ratios, thus it refers to multiple units of size reduction. The milling work is done in two circuits, crushing and grinding. The grinding reduction ratio is very higher than the crushing.
