【本刊讯】在深入揭批“四人帮”,贯彻执行英明领袖华主席抓纲治国伟大战略决策,掀起工业学大庆新高潮的大好形势鼓舞下,湿式旋流除尘风机扩大试用工作又有了新的进展。现将福山铜矿、大厂锡矿、青城子铅锌矿、五龙金矿、荡萍钨矿、南京凤凰山铁矿、湘东钨矿、锡矿山矿务局等八个矿山测定使用情况介绍如:(一)福山铜矿先后使用了两台。一台用于地面选厂中破碎皮带走廊抽尘净化,另一台用于井下溜矿井除尘。地面选厂的一台对除尘效率进行了测定,入口浓度37.7毫克/米~3,出口浓度1.29毫克/ Encouraged by the thorough investigation and approval of the “Gang of Four,” and with the excellent situation of wise leadership of Chairman Hua grasping the great strategic decision of the country governing the rule of law and setting off a new upsurge of industrialization, a new pilot project has been set up to expand the trial of wet cyclone dust blower Progress. Now Fukuyama Copper Mine, Dachang Tin, Qingchengzi lead-zinc mine, Wulong gold mine, Pingping tungsten mine, Nanjing Fenghuangshan iron ore, tungsten ore east, tin mines and other mines and other mines measured the use of Introduction such as: (a) Fukuyama Copper has used two. One for the ground processing plant broken belt corridor dust purification, and the other for mine dust downhole. One of the ground processing plant for dust removal efficiency was measured, the inlet concentration of 37.7 mg / m ~ 3, the export concentration of 1.29 mg /
