Crusher size reduction ratio calculation method 2015 7 14crusher size reduction ratio is the ratio of raw material particle size and particle size of crushingcalculated method are the following 1 with the maximum size and the broken material after the product before the maximum particle size ratio calculation britain and the united states in the 80 materials through sieve aperture width is theThe size reduction takes place quickly along short fracture lines producing a cubical product to meet aggregate specifications This fast impact fracture is different from the slow compression breaking in cone or jaw crushers that produce slabby or flat material (5 to 1 length to height ratio)
