I have mentioned the fact that, as the % of voids in thecrushingchamber decreases, the production of fines by attrition increases. This is like saying that, as theCrusher ReductionRatio in any givencrusheris 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 ...
