  • How to Calculate and Solve for Crusher Reduction Ratio

    The formula for calculating crusher reduction ratio: R r = G / S Where: 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 R r = 20 / 10 R r = 2
