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 5inches.
Any other size of product may be estimated in a similar manner.Note that if we had used a curve touching the 100 percent ordinate at the 0.75 value, we would have arrived at a value approximately 50 percent for the minus 0.25 fraction a value which is obviously erroneous for rock of average characteristics.
