自从廿年前首批大型自磨机和半自磨机安装在选矿厂之后就开始了致力于改善这些磨机衬板性能的研究。此时使用传统磨矿回路的选矿厂,磨机的作业率一般都在95％以上,而许多新建的自磨机和半自磨机回路却要为达到80％作业率而奋斗。磨机衬板维修不仅要消耗材料费用和人工费用,而且还降低了产量,因此很快就被公认为这是制约选矿厂生产的主要原因之一。 Since the first large self-mill and semi-autogenous mills were installed at the concentrator 20 years ago, research dedicated to improving the performance of these mill liners began. At this time, concentrators and mills using conventional grinding circuits are generally operating above 95%, while many new self-mill and semi-autogenous mill circuits are struggling to achieve an operating rate of 80%. Maintenance of mill liner not only consumes material and labor costs, but also reduces production and is quickly recognized as one of the major constraints to the mill’s production.
