Magnetic Separator Capacity. In the counter-rotation unit, the drum rotates against the inward flow of dilute medium. As the medium passes through a slot having a preset depth, magnetite is attracted to the drum. The drum can be adjusted to obtain different medium depths. Losses are typically no more than 0.25 grams/liter of non-magnetic product.
