Analysis of collision damage of Fritillaria ussuriensis Maxim during drum screening

In the drum screening of Fritillaria ussuriensis Maxim (FUM), collision among FUMs is one of the main causes of mechanical damage. Currently, research on collision damage of FUM is limited, and the parameters involved in drum screening are difficult to control. In this study, an impact test bench was used to simulate bulb–bulb collision during the process of drum screening, The variance in the absorbed energy and mass loss ratio was highly significant for bulb–bulb collisions. The influence of the mass relationship, and impact height, position, and direction on the absorbed energy were also highly significant. However, the impact direction did not have a significant effect on the mass loss ratio. The research findings serves as valuable reference for designing and developing low-loss drum screening processes.
