Magnetic separators, whether magnetic pulleys, suspended magnets or magnetic drums that are placed appropriately in a system can remove or sort these ferrous materials from those that are non-magnetic. Magnetic drums have permanent magnets for continuos, low-cost separation and can be installed inside closed chutes, at outlets of chutes and hoppers, or where materials discharge from feeders and conveyors. SWAC was a parallel machine with magnetic drum memory. |
