Crusher Reduction Ratio - Mineral Processing & Metallurgy
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 the product is affected depends to a much greater extent upon the ratio-of-volume-reduction in the crusher chamber than it does upon the actual degree …

The difference between a conventional impactor and a VSI of the liming type is that the latter offers lower operating costs, but its reduction ratio is lower also. In a liming VSI, the material undergoes an intense rock-on-rock crushing process. In the other crushers, most of the reduction is done by the impact of stone against metal.
