Impact Crusher Article

Apr 01, 2015 In all the impact crushers, there are significant numbers of rock–rock collisions which contribute to secondary breakage and to the resulting fineness of the product material. This means that modelling based on independent analysis of single particles is missing important aspects of the particle flow and breakage dynamics

The influence of the wear of the rotor bar on its impact effect was investigated with FEM simulation. The effectiveness of FEM simulation on the research of impact force was verified through the comparison of experiment and simulation data. Simulation results showed that the wear of rotor bar has not so large influence on impact force. In its initial stage, the bar is worn easily, and the wear
