The milling work is done in two circuits, crushing and grinding. The grinding reduction ratio is very higher than the crushing. Besides, each stage product is the feed for the next stage, and usually, the reductio ratio becomes higher as far as we go finer. These are useful information for you when dividing the global ratio into multiple values.
