Magnetic Separator - an overview ScienceDirect Topics

IEA Coal Research, in The Problems of Sulphur, 1989. High gradient magnetic separation (HGMS) Conventional magnetic separators are largely confined to the separation or filtration of relatively large particles of strongly magnetic materials. They employ a single surface for separation or collection of magnetic particles.

Clean Coal Processing - Eriez

Modern magnetic separation equipment is essential in the removal of tramp iron for coal processing. Since pull strength of today’s magnets is much greater than its predecessors, magnetic separators are an even more effective tool for pre-venting costly damage and shutdowns. Through the installation of advanced magnetic separation equipment, coal
