“…Inspired by the bionic design method, a convex pattern surface is introduced [6] and optimized [7] to reduce the sliding wear of the surfaces of bulk solids handing equipment by using a discrete element method (DEM). Many works [8][9][10][11][12][13][14][15][16] have been completed on the investigation of sliding wear caused by the bulk material based on the DEM method, while other studies [9,[11][12][13][14]16] whilwhile seldom focused on the influence of particle size on sliding wear. Although the previous studies have shown that the convex pattern surface can significantly reduce sliding wear compared with the flat surface, the effect of particle size is still unknown.…”

Sliding wear of bulk handling equipment (e.g., shovel bucket, mill and transfer chute) can be dramatically reduced by using a convex pattern surface compared to a flat surface, by adjusting the flow behavior of particles moving along the convex pattern surface. To study the effect of particle size relative to the dimensions of the convex pattern surface, a coarse graining technique is applied. Comparisons of bulk flow and wear behavior between the convex pattern and flat surfaces illustrate the two-sided effect of the convex pattern surface on sliding wear. The bulk flow behavior indicates that the particle size has a minor effect on the velocity and angular velocity of particles for the flat surface, while it has a significant effect on those of the convex pattern surface. The wear results show that the particle size has negligible influence on the sliding wear of a flat surface and a linear relationship with the sliding wear of the convex pattern surface. The convex pattern surface can reduce the sliding wear through influencing the flow behavior of the bulk material when the equivalent radius of the convex is larger than r50 of particles. This research reveals the relationship between the dimensions of the convex pattern and the particle size on the sliding wear caused by the interaction between bulk material and bulk handling equipment. The relationship should be carefully considered for the applications of the convex pattern surface to bulk handling equipment.

For material fracture and severe wear in braking conditions, the discrete element method (DEM) is used to simulate the wear process of the braking interface explicitly. Based on the central difference method, particle motion equations are established considering the influence of elemental damping on particle contact. Combined with the Particle Flow Code (PFC) software, a DEM wear model of the braking interface is established using the parallel bond modeling method. The braking wear process is simulated, and the material damage process is investigated. The simulation results demonstrate that with the increase of the initial braking load and the initial braking speed, the wear depth increased by 24.75% and 16.22%, respectively. The increase in the number of detached particles leads to an increasing trend of fracture force chains, which increases the thickness of the flowing particle layer, revealing the micro-wear mechanism of the braking interface.

During long-term operation, the scraper conveyor chute is seriously attrited by the friction of coal, gangue, and scraper chain. In this study, the discrete element method was applied to establish the bulk coal–scraper conveyor interaction analysis model to predict the wear of a scraper conveyor chute during the transporting process. The wear of the chute was investigated under various working conditions and bulk coal characteristics. Results indicated that the chute wear has a negative correlation with the laying angle of the scraper conveyor and increased with the chain speed. The wear was more severe as the increasing of gangue content, hardness, and size of the coal particles. In addition, the wear degree in different sections on the chute was predicted. Results showed that the section near the coal falling point underwent more intense collisions and impact and, thus, the wear was more serious at this location. The wear loss decreased with the increasing distance away from this point. This research can be used for predicting the wear of a scraper conveyor working under different mines. What’s more, the wear-resistant treatment can be applied on the particular areas according to the mine conditions based on this study.
