Rock Crushing Rule of Thumb Mineral Processing Metallurgy

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.
