  • Crusher Reduction Ratio Mineral Processing Metallurgy

    Jan 12, 2016  Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchangedCrusher 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 the Crusher Size Reduction Ratio Calculation MethodReduction Ratio Range For Jaw Crusher reduction ratio range for jaw crusher,sep 19 2012jaw crushers offer reduction ratios of up to about 61 while cone crushers can reduce material size up to a maximum of 81 ratio the finer the crushing the smaller the reduction ratio as a basic rule jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher reduction ratio range for jaw crusher
