Drum Separator
Low-intensity wet separation is widely used for recycling (and cleaning) magnetic media in dense medium separation (DMS) processes (see Chapter 11) and for the processing of ferromagnetic sands. The general design of drum separators is a rotating, hollow, nonmagnetic drum containing multiple stationary magnets of alternating polarity.
