Abstract: A new design method of cone crusher chamber based on interparticle breakage and population balance model is put forward and the chamber optimization model is built up. The output calculation method and optimization model of cone crusher based on kinematic character of granular material are put forward. The size distribution and optimization models based on population balance model are put forward. Besides, multiobjective planning of crushing chamber, output and size distribution is built up, which settles down the theoretical basis for developing new style, high efficiency, energy-saving cone crusher. Moreover, the multiobjective planning of cone crusher is also used to improve the existed cone crusher by crusher manufacturer and the validity and reliability are verified by the related full scale tests.

Key words: Cone crusher, Granular material, Interparticle breakage, Optimization design, Population balance model
