  • Calculate the Reduction Ratio and the Number of Milling

    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 valuesTotal reduction ratio Source: minevik Crushing is done in three, or four stages while grinding is done in one, or three stages If you don’t have many stages as shown on the app put 1 in the stages that you are not using Calculate the total reduction ratio of a milling circuit by multiplying the reduction ratios of every stageReduction Ratio/ Milling Stages Calculator Formula
