Abstract
The test results of a conduction-cooled High Temperature Superconducting (HTS) Reciprocating Magnetic Separator are reported. Reciprocating magnetic separators are used in the purification of kaolin clay. The HTS coil is 0.3 m in length and has a 0.25 m (cold) bore inner diameter. The central operating magnetic field is a nominal 3.0 T with a design operating current of 126 A. In terms of combined size and magnetic field strength, this is one of the largest HTS magnets ever fabricated, possessing a stored energy >0.1 MJ. The HTS magnet is conduction cooled via one single-stage G-M cryocooler with a nominal operating temperature of 30 K. The HTS conductor uses a stainless steel reinforced Bi-2223 material. Salient design features and test results of the HTS magnetic separator are discussed.
