波峰高度及结构形式对磨球机衬板工作性能的影响研究

Study on the Influence of Wave Height and Structural Form on the Working Performance of Ball Mill Liners

摘要

针对磨球机衬板的波峰高度及结构形式对其工作性能的影响开展系统研究。通过建立衬板-介质运动学模型与磨损仿真模型，分析不同波峰高度（15~65mm）条件下衬板的提升能力、研磨效率及磨损速率的变化规律。结果表明，波峰高度存在最优取值区间（35~45mm），在此范围内衬板综合工作性能最佳；同时，非对称波形结构较传统对称结构可提升研磨效率约12%~18%，降低衬板磨损率约8%~15%。研究成果为磨球机衬板的优化设计提供了理论依据与技术参考。

Abstract

This study systematically investigates the impact of wave peak height and structural configuration on the operational performance of ball mill liners. By developing a kinematic model for liner-media interaction and a wear simulation model, we analyzed variations in liner lifting capacity, grinding efficiency, and wear rate under different wave peak heights (15-65 mm). Results indicate an optimal wave peak height range (35-45 mm) that yields the best overall liner performance. Additionally, asymmetric wave configurations improve grinding efficiency by approximately 12%-18% compared to traditional symmetric designs while reducing liner wear rates by about 8%-15%. These findings provide a theoretical foundation and technical guidance for optimizing ball mill liner design.
