Abstract:In order to clarify the internal factors affecting the grinding action of tower mills, the influence mechanism of structural parameters and process parameters on the grinding energy consumption was investigated based on the laboratory five factor four level orthogonal experiment. Based on the discrete element method, the same condition simulation was conducted to explore the variation laws of mechanical parameters, kinematic parameters, and energy parameters of grinding media. The comparison analysis of the two shows that: the tangential force and normal force between the media are the intrinsic factors that affect the grinding action of the vertical mill. The research on the fine grinding mechanism of the vertical mill and the optimization and amplification of the equipment have important guiding significance.
