• Crusher Reduction Ratio Mineral Processing &

    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 unchanged Both of these statements are true, but the degree to which
