悬磁干选机预选试验

Preconcentration Test of Magnetic Suspension Dry Separator

大孤山球团厂采用悬磁式干选机对肛12mm入选矿石进行了干式预选试验研究。结果表明悬磁式干选机结构先进、选别效率高，可预先抛出产率17％以上、磁性铁含量1％以下的废石。提高入选品位2％以上。

A research on the dry preconcentrate test is carried out for 0 mm to 12 mm ore separat-ed by the magnetic suspension dry separator in Dagushan Pellet Plant. The result shows that the struc-ture of the magnetic suspension dry separator is advanced, separation efficiency is high, and the ganguecontented 1% magnetic iron with above 17% yield can be thrown out in advance. The milling grade is increased by over 2%.
