摘　　要：介绍了球磨机衬板所用的金属、橡胶及复合材料的性能及研究进展,其中耐磨铸铁有良好的耐蚀和抗氧化性,马氏体钢在中等冲击磨损情况下,综合力学性能好,贝氏体钢淬透性好,马氏体-贝氏体钢在保持较高强度的同时,可提高材料的塑性和冲击韧性,高锰钢具有较高的冲击性能和耐磨性;橡胶衬板重量轻,易安装,噪声小,消耗动力小,但不适于干法原料球磨机;复合材料具有可设计性和良好的综合性能。最后,概述了衬板的失效形式,磨料磨损除与材料硬度有关外,还与磨料的硬度与材料的硬度比有关。The properties and research progress of metals,rubber and composite materials used for the liner board of ball mills were introduced.Wear-resistant cast iron is featured with good corrosion resistance and oxidation resistance,martensitic steel with good comprehensive mechanical properties under moderate impact wear,and bainitic steel with good hardenability;martensitic/bainitic steel can improve ductility and impact tenacity of materials while maintaining high strength,and high manganese steel shows high impact performance and abrasive resistance.Rubber lining is light in weight,easy for installation,and low in noise and power consumption,but it is not suitable for dry type ball mills,while composite materials show the satisfactory designability and good comprehensive performance.Finally,the failure modes of lining were summarized,notably,abrasive wear is not only related to the hardness of materials,but also to the ratio of the hardness of the abrasive to the hardness of materials.
