“…After several crushings, the particles are discharged from the crushing chamber. According to the structural and operating parameters of the cone crusher, the motion characteristics of particles in the crushing chamber can be determined such that the path of the particles in the crushing chamber can be obtained [26]. Then, the crushing chamber can be divided into several crushing zones, as shown in Figure 4.…”

The crushing chamber is the core component of a cone crusher, consisting of mantle and concave parts. Reducing the impact of crushing chamber wear on the performance of cone crushers and the quality of crushed products while extending the service life of the mantle and concave has become a significant research challenge. The impact of the compression ratio and particle size distribution coefficient on the particle crushing pressure is investigated here in order to establish the particle pressure model. The effect of the normal and tangential components of particle crushing pressure on the wear of the mantle and concave is discussed, and the wear with the increase in crushed products and accumulation of operating time is explored in order to develop a wear model of the crushing chamber. By evaluating the compensation of the worn crushing chamber according to the adjustment mechanism of the mantle, a constant wear criterion for the crushing chamber of the cone crusher is proposed. Through analysis of industrial experimental data on an experimental prototype of a ZS200MF cone crusher with an optimized mantle and concave, the capacity was found to fluctuate at 83.45 t/h with no apparent downward trend, the calibration size production was reduced by 6.2%, and the wear similarity coefficient was 8.82%. This indicates that replacing the optimized mantle and concave based on the constant wear criterion maintains the performance of the cone crusher, delays the decline in the quality of the crushed products, and ensures similarity between the adjusted worn crushing chamber and the initial crushing chamber, which verifies the feasibility and effectiveness of the constant wear criterion for the optimization of crushing chamber. Based on the constant wear criterion, cone crushers can be optimized to obtain a crushing chamber with constant wear characteristics, which provides theoretical support for the development of new high-efficiency cone crushers as well as the optimization of existing equipment.

“…Based on the continuum model of particles [11], Oliver et al [12] explored the capacity of the cone crusher, which was simplified to a two-dimensional channel. Zhang et al [13] investigated the motion characteristics of the particles affected by the spatial compound motion of the mantle and explored the path of the particles in the crushing chamber. As computer numerical simulation technology advances, the discrete element method (DEM) was gradually adopted in the research of cone crusher capacity [14][15][16].…”

Capacity is the important indicator of the cone crushers, which is determined by the motion characteristics of particles. The spatial compound motion of the mantle, which rotates both around the central axis of the cone crusher and its central axis, was analyzed to develop motion characteristic equations of particles. The velocity distribution of particles with different motion characteristics was determined by solving the motion characteristic equations of particles using the coordinate system transformation matrix. An improved capacity model of the cone crushers based on the motion characteristics of particles considering the influence of the spatial compound motion of the mantle was established by analyzing the velocity of particles in the upward and downward direction zones of the choke-level and the influence of circumferential deflection of particles on the velocity in the radial direction. A reduced-scale cone crusher with various rotational speeds was used to simulate cone crushers with different motion characteristics of the particles passing through the choke-level. The average error between the capacity calculated by the improved capacity model and the capacity determined according to the experimental data was 5.96%. Therefore, the accuracy of the improved capacity model was verified. The improved capacity model was used in the capacity calculation of the ZS200MF cone crusher; the error was 7.4% compared with the measured value at the production site; thus, the applicability of the improved capacity model is proved. The influences of four typical parameters of the cone crusher on capacity were investigated based on the improved capacity model, which provides theoretical support for the development of new high-efficiency cone crusher and the optimization of existing equipment.
