O koncepcjach modelowania maszynowych procesów kruszenia

One of the investigation trends in the mechanics of comminution (crushing and grinding) is modelling of machine processes. The work presents different conceptions (ideas) of this modelling. The matrix model formulated by Epstein, Broadbent and Callcott is shortly described. The cubic model according to the hypothesis of the crushing work multiplicity (I. Brach), the sphere model I and II as well as the cubic model are described in details (these are the new conceptions developed by the author).
