Abstract
What is presented is a permanent magnet drum separator for removal of a ferrous fraction from a material stream comprising a pickup magnet that is a rare earth permanent magnet that can be moved within the drum separator. The drum separator comprises a rotatable outer shell having tubular shape with a circular cross section. The drum separator includes a carry magnet that is positioned at a fixed location within the rotatable outer shell near the inside circumference of the rotatable outer shell. The pickup magnet is positioned on a hinge plate within the rotatable outer shell. The hinge plate has a first end attached to a hinge and a second end attached to a movable element. The hinge is positioned at a fixed location within the rotatable outer shell near the inside circumference of said rotatable outer shell. The movable element is able to move the pickup magnet about the hinge to vary the distance between the pickup magnet and the inside circumference of the rotatable outer shell.
