在选煤厂中湿式鼓型磁选机是重液选煤用的一种辅助设备,它是用来回收选煤重液介质-磁铁、硅铁最有效的机械。日本三井矿山公司三池选煤厂从71年起采用这种湿式鼓型磁选机,至今经过7年,进行了许多技术改进,已逐步发展、完善。为满足磁选要求,湿式鼓型磁选机应具备以下条件。 In the coal preparation plant, the wet drum type magnetic separator is an auxiliary equipment for heavy liquid coal preparation. It is the most effective mechanical for recovering heavy medium of coal preparation - magnet and ferrosilicon. Japan’s Mitsui Mining Company Sanchi coal preparation plant since 71 years using this wet drum magnetic separator, so far after seven years, many technical improvements have been gradually developed and improved. To meet the magnetic separation requirements, wet drum type magnetic separator should have the following conditions.
