General theory and methods of calculation of the results of rock crushing and their subsequent gravitational enrichment

Abstract
Methods for calculating yields and compositions of functions in gravity concentration have been developed for fine and coarse crushing. Calculation of coal crushing and its subsequent gravity concentration was carried out for coarse and fine crushing by different methods, which is a shortcoming of the theory. In addition, for some intermediate cases it is sometimes unclear which method should be used, and calculations by the coarse and fine crushing method give drastically different results.
