• New equations for the kinetics of crushing and their

    The author has derived new equations of crushing kinetics, expressing the variation of the sieve residue surface, relative to that of the grains of the control size, with the crushing time 2 The use of these equations enables one to calculate the increase in mill output according to the degree of decrease in the initial ore size, its hardness, and the crushing size
