摘要
针对带式输送机转载结构头部挡板、底部衬板磨损严重的现象,利用离散元仿真技术对影响结构磨损的煤料参数、转运结构参数进行分析,结果表明:在装运过程中,适当减小单元煤料颗粒粒径,可以增加转运系统的使用寿命;适当减小给料匙角度,可有效降低转运煤料对底部衬板的磨损现象。研究结论将为矿用装备的优化设计提供理论依据与数据支撑。
Aiming at the serious wear of the head baffle and bottom lining plate of the reloading structure of the belt conveyor,the discrete element simulation technology is used to analyze the parameters of the coal material and the transfer structure that affect the structural wear.Small unit coal particle size can increase the service life of the transfer system;appropriately reducing the angle of the feeding spoon can effectively reduce the wear of the transfer coal on the bottom lining.The research conclusions will provide theoretical basis and data support for the optimal design of mining equipment.
