The Development of 5.5 T High Gradient Superconducting Magnetic Separator

A new High Gradient Superconducting Magnetic Separator (HGMS) system was developed to process kaolin. This paper describes the development of a 5.5 T central field, 300 mm room temperature bore, HGMS system. A zero boil-off helium cryostat, a double canisters system, and a PLC (Process Logic Controller) fully automatic control system based on SCADA (Supervisory Control And Data Acquisition) system have been designed for the HGMS. Every part works very well. Some experiments on processing kaolin clay used HGMS have been carried out. This paper will show the detailed development of every part.
