Effect of Feed Rock Size Distribution on Crusher Performance

22/10/2015  The effect of the undersize in the feed upon the capacity of the crusher depends upon several factors. If the crusher is a primary breaker, and the discharge opening is large, undersize will usually sift readily through the voids between the large pieces of material, and discharge quickly. The material must, of course, be free-flowing to behave in this manner. For such a condition, large quantities of undersize
