Intensity Magnetic Separator
The magnetic field gradient in the separation zone (approximately 50 mm from the drum surface) ranges between 0.1 and 0.3 T. Below 0.5 cm, dry separation tends to be replaced by wet LIMS. Concurrent and countercurrent drum separators have a nonmagnetic drum containing three to six stationary magnets of alternating polarity.
