Reduction Ratio/ Milling Stages Calculator Formula

Mar 28, 2021 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 stage. Total Reduction Ratio R/R1 R/R2 R/R3 R/R4 R/R5

Bond Work Index. In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the 'Bond Work Index', which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 journal article. Bond called his theory the "third
