Recent advances in magnetic separator designs and applications

Temperature management to enable dry magnetic separation can involve added costs if feed cooling is required, particularly in cases where downstream process operations require additional energy input to re-elevate the material temperature. RER concerns Belt concerns The traditional RER can offer high magnetic strength, since there is essentially zero clearance between the magnetic roll and the
