地下选矿厂磨机(半自磨机)机械振动研究综述

Mechanical vibration research on grinding mills(semi-autogenous mills)in underground processing plant:a review

地下选矿厂磨矿硐室(半自磨机硐室)需要承受磨矿设备筒体内矿石、介质和筒体交互冲击产生的机械振动作用。对国内外学者及工程技术人员针对与半自磨机类似的球磨机、磨煤机等设备,从数据采集及分析方法、改进设备作业效率、监控设备运行性能及保持设备基础稳定方面取得的研究成果进行了综述,总结了磨机(半自磨)机械振动信号采集、分析识别方法、仿真反演及实际应用等方面研究成果,具有较高的借鉴意义。

The underground ore processing plants′grinding chambers(semi-autogenous grinding caverns)need to withstand the mechanical vibration caused by the interaction of ore,medium,and the barrel within the grinding equipment.This article reviewes the research achievements of domestic and foreign scholars and engineering technicians for equipment similar to semi-autogenous mills,such as ball mills and coal mills,from the perspectives of data collection and analysis methods,improving equipment operating efficiency,monitoring equipment performance,and maintaining equipment foundation stability.The article summarizes the research results in terms of mechanical vibration signal collection,analysis and identification methods,simulation inversion,and practical application of grinding mills(semi-autogenous),providing significant reference value.
