Abstract

A magnetic separator having a chassis, a rotor and a return roll supported on the chassis, the rotor and return roll having axes extending parallel to each other, and an endless band trained over the rotor and return roll, the endless band having an upper course and a lower course, the chassis being constituted by a beam positioned between the upper and lower course of the endless band. A frame supports opposite ends of the beam projecting from the opposite sides of the endless band at a plane of support, one of the beam ends being rigidly fixed on the frame, and a removable shim is positioned at the level of the lower course of the endless band adjacent the plane of support, the removable shim supporting the beam end opposite the one beam end on the frame whereby the beam is cantilevered on the frame when the shim is removed and a space is defined between the opposite beam end and the frame, the space permitting the endless band to be dismounted from, and mounted on, the rotor and return roll. Furthermore, a tensioning device applies an operating tension to the endless band mounted on the rotor and return roll, and may be deactivated to reduce the tension.
