Abstract
Reciprocating magnetic separators are used in the purification of kaolin clay and titanium dioxide. Design parameters and fabrication details are reported for the high temperature superconducting (HTS) coil. The HTS coil is 0.7 m in length and has a 0.5 m inner diameter. The central operating magnetic field is a nominal 3.0 T with a design operating current of 100 A. In terms of combined size and magnetic field strength, this is one of the largest HTS magnets ever fabricated, possessing a stored energy > 0.400 MJ. The HTS magnet is conduction cooled via single-stage G-M cryocoolers with a nominal operating temperature of 30 K. The HTS conductor uses a stainless steel reinforced Bi-2223 material. Salient features and results of the electromagnetic and thermal analyses are discussed.
