Abstract: Granular material mechanics, finite element analysis and crushing theory are applied to study the compressive comminution mechanism of particle beds in this paper. This is a new method by which we have established an equivalent model of granular material, determined the values and distributions of contact forces and discovered a crushing law. The model has been tested on the newly designed equipment and proved to be correct.Some new characteristics and laws of compressive comminution of particle beds have been found.
