How to Calculate and Solve for Crusher Reduction Ratio | Mineral Processing

R r = Crusher Reduction Ratio G = Gape Size S = Set Size. Let's solve an example; Find the crusher reduction ratio when the gape size is 20 and the set size is 10. This implies that; G = Gape Size = 20 S = Set Size = 10. R r = G / S So, R r = 20 / 10 R r = 2. Therefore, the crusher reduction ratio is 2. Calculating the Gape Size when the ...
