Study on the Impact of Muck-pile Size Distribution on Cyclic Impact Crushing Efficiency

Zhesen Cui

Abstract

The distribution of block sizes in a muck pile directly affects subsequent mechanical crushing efficiency. To investigate the crushing
mechanism of ore particles during cyclic impact, cyclic impact tests were conducted on ore samples within different size ranges. The stressstrain curves, peak stress, and peak strain variations of the specimens were analyzed. PFC3D simulations were used to study the microscopic
mechanisms of ore crushing. The influence of size distribution on crushing efficiency and crack propagation was examined. The results indicate that as the number of impact cycles increases, the dynamic response of specimens with a single size distribution tends to stabilize, while
the peak stress of specimens with a complex size distribution increases by 4.47 to 6.68 MPa. Under cyclic impact, the tensile stress within the
specimens is higher, and the predominant failure mode of the ore is tensile fracture. Ore specimens in the 3-6 mm and 12-15 mm size ranges
have a significant impact on the overall crack propagation direction, with the crack length decreasing as the size increases. Specimens with
complex size distributions show more pronounced stress concentration effects, resulting in stronger particle interactions that facilitate the
propagation of internal cracks. These findings are useful for optimizing muck pile size distributions to improve ore crushing efficiency.
