摘要
For the models built up on the basis of the nonlinear elastoplastic theory describing the collisions of solids, parameters of impact interaction between the working bodies and the material to be treated have been calculated for a series of comminuting devices, i.e., different types of ball mills, disintegrator, etc. Pressure and temperature impulses at the contacts of the treated particles have been calculated. Generalised equations have been deduced for the kinetics rate constants of mechanochemical reactions and for the mechanical activation of the substances in comminuting devices.
