摘要： The impact damage is the most destructive effect on FUM during the drum screening. To explore the impact damage of FUM during drum screening, a free-drop test device was built to simulate the impact damage of FUM. Adopting an L-16(4(5)) orthogonal experiment scheme, we investigated the effect of mass, dropping height, collision material, and number of collisions on the bruise depth and specific surface area of bruise, impact peak force, and Ratio of amplitude attenuation. Then, we analyzed the influence of these four factors using a single factor test for each factor. Orthogonal experiments identified the main and secondary factors affecting each outcome; the number of collisions had no significant influence on the impact peak force, while the collision material was the only factor with a significant influence on the Ratio of amplitude attenuation. Single-factor test results indicate that the bruising depth and maximum impact force increase with FUM mass, and the specific surface area of the bruise first increases and then reduces. The maximum impact force and the bruising depth increase with dropping height, and the specific surface area of the bruise periodically changes. The bruising depth and damage surface area of FUM increased with an increased hardness of the collision material, and the maximum impact force and ratio of amplitude attenuation decreased with an increased hardness of the collision material. The specific surface area of the bruise periodically changes with the drop time, and the bruising depth first increases and then decreases.
