【摘要】 半自磨机作为物料磨碎作业的核心设备，其衬板的磨损特性直接影响设备的使用寿命和运行效率。基于此，针对 L 形衬板的 2 种安装形式 (T 形与 L 形)，开展筒体衬板磨损特性与磨矿效率的影响研究。通过仿真，结果表明：L 形安装形式衬板的碰撞区域颗粒动能比 T 形安装形式提高了 3.6%；L 形安装形式的提升条磨损速率增加 38%，但基底磨损速率降低 50%。现场磨损数据分析也进一步验证了仿真结果。研究表明，在筒体衬板使用初期，L 形安装形式的筒体衬板磨矿效率更高，具有提升条磨损增加、基底磨损减少的特点，能够提高矿石处理量，更好地保护筒体，提升设备运行效率与可靠性。更多还原

【Abstract】 As the core equipment of the material grinding operation,the wear characteristics of the liner of the SAG mill directly affected the service life and operation efficiency of the equipment.Based on this,the influence of wear characteristics and grinding efficiency of shell liners was studied with two installation forms (T-shaped and L-shaped) of the L-shaped liner.Through the simulation,the results showed that the kinetic energy of particles in the collision area of the L-shaped liner was 3.6% higher than that of the T-shaped liner.The wear rate of the L-shaped lifting bar increased by 38%,but the wear rate of the base decreased by 50%.The analysis of the wear data on site further verified the simulation results.The research showed that in the early stage of the use of the shell liner,the L-shaped shell liner had higher grinding efficiency,with the characteristics of increased wear of the lifting bar and reduced wear of the base,which could improve the ore processing capacity,better protect the shell,and improve the operation efficiency and reliability of the equipment.更多还原
