艾砂磨机在细磨中的优势及其在有色金属选矿厂的应用

磨矿作业在金属矿山选矿工艺中是一个高能耗、高材耗的过程,尤其是多段磨矿的选矿厂,磨矿能耗已占到选矿厂能耗的50%以上,磨矿成本占选矿厂成本的30%以上。其中作为细磨作业的二段和三段磨矿,磨矿效率低下,粒度分布不均匀,过磨和欠磨现象严重,对后续分选作业产生不利影响。艾砂磨机细磨作业具有高效节能的特点,变频调速解决了流程物料不稳定的问题,磨矿产品粒度分布窄、避免过磨和欠磨可有效提高有价金属回收效果,开路磨矿工艺达到闭路磨矿效果,简化了设备配置,设备占地面积小可减少建设投资,改造更加方便,独特的结构设计使维修非常简便,可有效提高选矿厂运转率。近几年来,艾砂磨机在国内外多个矿山落地应用,多个案例证明,艾砂磨机设备运行稳定,在细磨段具有节能降耗的显著优势,对提高精矿品位和回收率具有显著的效果。

the Advantage of ALC Mill in Fine Grinding and Application in Nonferrous Metal Concentrator

Grinding operation is a process of high energy consumption and material consumption in the beneficiation process of metal mines, especially in the multi-stage grinding concentrator, the grinding energy consumption has accounted for more than 50% of the energy consumption of the concentrator, and the grinding cost accounts for more than 30% of the cost of the concentrator. Among them, the second and third stage grinding, as the fine grinding operation, has low grinding efficiency, uneven particle size distribution, serious over grinding and under grinding, which has a negative impact on the subsequent separation operation.
