ABSTRACT Screening is used extensively for the size classification of coals. During the screening process, the impact of oversized material often causes damage to the screen surface, which then affects the reliability of the vibrating screen. In this study, an orthogonal experiment was designed, and the influence of vibration parameters on impact force was determined using range and variance ...
