Optimization of particle size distribution in circulating fluidized

Next, the two-toothed roll crusher was optimized based on the framework proposed by the Whiten model. The reasonable rolls gap and teeth length should be 75 mm and 23 mm, respectively. Further, a physical model of a two-toothed roll crusher was established to obtain the optimized roll diameter; it was later found to be >660 mm.

Effect of Feed Rock Size Distribution on Crusher Performance

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 …
