- magnetic separators weak
An open-gradient drum magnetic separator with a superconducting magnet system has been operating commercially since the 1980s ( Unkelbach and Kellerwessel, 1985; Wasmuth and Unkelbach, 1991 ). Although separation is identical to that in conventional drum separators, the magnetic flux density at the drum surface can reach over 4 T.
