The improved model of inter-particle breakage considering the transformation of particle shape for cone crusher

A full-scale test with ZS200MF cone crusher was conducted in Tangshan, China. The particle size distribution and particle shape component of the crushing product were investigated by simulation with the improved model. Through the comparison of the measurement and the simulation, the maximum error of cumulated weight distribution is 4.8%, and the maximum error of flakiness index is 4.6%, then the effectiveness and practicability of this model are proved. Thus, the improved model can predict the quality of crushing product by utilizing the granular property of feed, the geometry of crushing chamber and operational parameters of cone crusher, which provides a theoretical foundation for product quality improvement, high-energy crushing chamber design and operational parameters optimization of cone crusher.
