Industrial test study on the application of KLM vertical mill to the first stage mill in a concentrator
KLM型立磨机应用于某选厂一段磨的工业试验研究

摘要

为进一步提高某选厂锡铜共生矿细粒级物料磨矿效率、降低成本提供依据，对4000吨/日一段磨给矿德瑞克筛筛上产品进行立磨机磨矿试验研究，提高磨矿效率，减少流程返量，使其排矿粒度稳定在-200目含量40%以上，同时保证磨矿产品中-0.010mm级金属率在10%以内。工业实践表明，KLM型立磨机是一种适合于金属矿细磨与再磨作业，节能高效的磨矿设备。

Abstract

In order to provide a basis for further improving the grinding efficiency and reducing the cost of fine-grained materials of tin-copper co-biore in a dressing plant, the vertical mill grinding test study was carried out on the products on the Dreke screen of 4000 tons/day for a stage grinding ore, so as to improve the grinding efficiency and reduce the flow return, so as to keep the ore size stable at 200 mesh content more than 40% at the same timeThe metal rate of 0.010mm in grinding products is less than 10%. The industrial practice shows that the KLM type vertical mill isThe utility model relates to an energy saving and efficient grinding equipment suitable for fine grinding and regrinding of metal ore.
