燃化部于1970年试制成功XJM-4型浮选机,全国新建、扩建选煤厂大都已采用,现已成批生产,并列入一机部系列标准。XJM-4型浮选机具有容积大,外形尺寸小,重量轻,处理量大,工艺流程灵活,操作方便等优点。有些单位采用它,达到了生产能力0.8～1.2吨/时·米~3、充气量1.3米~3/分·米~2、电耗3瓦/吨·时的先进指标。一、技术规格见下表。二、结构与工作原理XJM-4型浮选机有四槽和六槽两种,六槽浮选机结构见下图。由六个箱体1、五个中矿箱4及一个尾矿箱8组成。每个箱体
In 1970, the Ministry of Fuel Oil successfully trialled the XJM-4 flotation machine. Most of the newly-built and expanded coal preparation plants in China have been adopted and are now mass-produced and included in the standard of a machine department. XJM-4 flotation machine has the advantages of large capacity, small size, light weight, large capacity, flexible process flow and convenient operation. Some units adopt it and reach the advanced index when the production capacity is 0.8 ~ 1.2 tons / hour · m ~ 3, the inflating capacity is 1.3m ~ 3 / min · m ~ 2 and the power consumption is 3W / t. First, the technical specifications in the table below. Second, the structure and working principle XJM-4 flotation machine has four slots and six slots two, six slot flotation machine structure shown below. It consists of six boxes 1, five middle mine boxes 4 and one tailings box 8. Each box
