Crusher Reduction Ratio Mineral Processing & Metallurgy

Mar 19, 2017 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,

Introduction to Rock Crushers

Jaw crushers offer reduction ratios of up to about 6:1, while cone crushers can reduce material size up to a maximum of 8:1 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 can accept.
