Effect of Feed Rock Size Distribution on Crusher Performance

If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher could not shatter the large pieces enough to keep the rest of the crushing chamber busy. Such a condition is of course ...
