About setting coarse tailings cyclone separator off the mud problem by experiments prove that this part of the fine mud iron grade is not very high yield is relatively low, tailing iron direct loss of less than 3%, neodymium segment magnets has little effect on iron recovery, But Outward vertical ring magnetic flotation and subsequent desulfurization, especially for relatively large filter, the test measured filtration efficiency and primary ore than 30% lower. Therefore, neodymium cylinder magnets the decision directly tailing. This product is the use of high-tech innovation and technology, into a more user-friendly design of permanent magnet lifter for lifting all kinds of flat steel。
