目前,我国各大型黑色金属磁选厂广泛采用的是B=1000毫米的三产品带式磁选机。这种磁选机存在许多缺点,特别是生产能力和选别指标都比较低。在国外,这种磁选机已逐渐被新型的筒式磁选机取代。为了满足我国冶金工业日益发展的需要,北京矿冶研究院于1963年初设计了一种半逆流电磁筒式磁选机,由一机部沈阳矿山机器厂试制。1965年初,在半逆流槽体的基础上,沈阳矿山机器厂设计了逆流槽体和顺流槽体。于1964年5月到1965年9月,在本
At present, China’s large-scale ferrous metal magnetic separation plant widely used is B = 1000 mm three products with magnetic separator. There are a number of shortcomings with this type of magnetic separator, especially the lower production capacity and sorting index. Abroad, this magnetic separator has been gradually replaced by a new type of cartridge magnetic separator. In order to meet the needs of the development of China’s metallurgical industry, Beijing Mining and Metallurgy Research Institute in early 1963 designed a semi-countercurrent electromagnetic drum magnetic separator, a machine by Shenyang Mining Machinery Factory pilot. At the beginning of 1965, on the basis of semi-countercurrent tank, Shenyang Mine Machinery Factory designed counter-current tank and downstream tank. From May 1964 to September 1965, at Ben
