The invention belongs to the technical field of
beneficiation and particularly provides a
beneficiation device of complex ore containing
magnetite. The
beneficiation device of the complex ore containing the
magnetite comprises a supporting frame, a supporting box, a roller, a transmission, a fixing plate, a hollow rod, a micro-motor, a screw, a nut, a first moving plate, inclined rods, fixing blocks, first rotating pins, auxiliary rods, bolts, a second moving plate, an inner rod, a rotating rod, a first spring, a fixing pin, a reset
coil spring, a first magnetic block, a second magnetic block,T-shaped blocks, T-shaped grooves, T-shaped rods, second springs, first racks, second racks, installation plates, scraper blades, arc grooves, third springs, arc rods and fastening bolts.The micro-motor works to drive the screw to rotate, the screw rotates to drive the nut to move along the screw, the first moving plate moves up and down, and then the transmission can be conveniently maintained;and when the first moving plate needs supporting, the inclined rods are rotated by means of the first rotating pins, the inclined rods are made to be attached to the first moving plate, the inclined rods rotate to drive the auxiliary rods to rotate into rectangular grooves, and then the inclined rods are fixed.
