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.
Key words: compressive comminution mechanism granular material equivalent model test machine of compressive comminution of particle beds
