Aiming at the defect of an inertia cone crusher such as violent vibration and poor product indexes, a systematic analysis method combining theoretical analysis, multi-body dynamics, and a discrete element coupling method, and test verification was proposed. For model verification, the industrial tests were conducted on a GYP 1200 inertia cone crusher. Two different drive speeds were included in the experiments, and the testing devices were used to sample crusher performances such as displacement amplitude, power draw, product size distribution and throughput capacity in order to verify the validity of the coupling model and the analysis method. Furthermore, the behavior of the particle flow and the crushing force distribution in the concave were predicted. Finally, the influence of key parameters such as different drive speed and fixed cone mass on the dynamic performance of the crusher was discussed in detail. The coupling simulations and study results provided a basis for the improvement of linings wear, lowering manufacturing cost, and obtaining optimal operation parameters.
