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.
Rock Crushing Rule of Thumb Mineral Processing &
Nearly all crushers produce a product that is 40% finer than onehalf the crusher setting. Source: Babu and Cook; The product of a jaw crusher will have a size distribution such that the 80% fraction size (d80) is slightly less than the openside setting of the crusher. For example, if the open side setting is 6 inches, the d80 product size will be 5¾ inches.

Cone Crusher Feed Distribution For fine crushing, or in installations where the feed to the crusher is irregular, the use of a wobble plate feeder is recommended. This feeder is installed in place of the spider cap and affords a means of controlling the feed to the crusher, as well as a means of distributing the feed evenly around the crushing chamber.
Comminution Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust.

Impact crushers provide better grainsize distribution of RA for road construction purposes, and they are less sensitive to material that cannot be crushed, such as steel reinforcement. Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material. A jaw crusher crushes only a small proportion of the
