Abstract: In order to develop new-type, more efficient, energy-saving and environment-preserving compressing crushers, based on matrix model of crushing process and chamber dividing results, compressing crusher manipulation model of the interparticle breakage is achieved, and is provided a new method for efficiently control crushing product quality. Using RMT-150B rock mechanics test system to simulate the interparticle breakage process of compressing crusher, the interparticle breakage process is studied and the selection model and breakage model are gained, which provided the basis for simulating and optimizing crushing product size-reduction. Besides, the interparticle breakage size-reduction optimization model of compressing crusher is accomplished, which is used to optimize the PYB900 cone crusher, and the feasibility and reliability of those models is verified by physical prototype of crusher manufacturer.
