A machine is described for magnetic separation of material, wherein the machine includes a supporting structure and at least one magnetic rotating drum supported by the supporting structure, wherein the machine further includes a vehicle for moving and transporting the supporting structure. The magnetic drum includes an outer rotating shell and a magnetic portion including at least one magnet positioned and housed within the outer shell, wherein the outer shell is rotatable around a central axis by a drive mechanism and the at least one magnet is positioned in a fixed location within the outer shell.

A magnetic separator is provided with one or more components that may enhance separation of magnetic and nonmagnetic materials. The one or more components may comprise at least one of a slide and a scraper blade.

A separator for extracting magnetic material from an airstream of magnetic material and non-magnetic material includes a planar chamber with an inlet port, outlet port and a waste port, and a series of magnets in a plane parallel to the chamber. The magnets rotate about a common axis thereby drawing magnetic material around the chamber and towards the outlet port whilst non-magnetic material is remains in the airstream and is discharged by the waste port.

A ferromagnetic material removing device for removing ferromagnetic material from a fluid containing ferromagnetic material is disclosed. The device comprises at least one carrier encasing a plurality of permanent magnets arranged in an inner space of the carrier. The outside of the carrier is configured to collect ferromagnetic material that is attracted by the magnets. The carrier is ring-shaped and rotatably mounted and the device comprises a removing portion arranged and configured to remove the ferromagnetic material from the outside of the carrier and a driving assembly arranged to rotate the carrier.

A method and apparatus for continuous magnetic filtration of ferrous mill scale from liquid solution employs a tank for receipt of fluids laden with mill scale. A curvate trough within the tank receives a rotatable magnetic drum and establishes a channel therebetween. An air compressor and associated manifold generate bubbles within the tank and adjacent the rotatable magnetic drum. The mill scale attaches to the bubbles, which are attracted to the surface of the drum where the mill scale accumulates. The accumulation of mill scale particles is moved about the surface of the rotating drum by a scraper proximate the surface thereof. By moving the accumulated mill scale particles to regions of the rotating drum that are of a magnetic force insufficient to retain them upon the surface of the drum, the mill scale particles are removed and passed to a conveyor system.

A separation device is described. The separation device includes a rack, a turntable rotatably disposed on the rack; and at least one magnetic element disposed on the turntable. The turntable includes a top surface, and the magnetic element is recessed in or flush with the top surface. The separation device includes a separation membrane detachably disposed on the top surface. In some cases, the at least one magnetic element comprises a plurality of magnetic elements, and the plurality of magnetic elements are spaced apart along a circumferential direction of the turntable. The separation device and a material separation method disclosed are capable of reducing impurities in a slurry.

A tailings recovery process comprises: feeding ore pulp into a concentration barrel of a concentrating machine; driving the concentration barrel to rotate around its own central axis while the ore pulp flows, so as to enable the ore pulp to be continuously stirred and turn over in inner cavity of the concentration barrel; applying a magnetic field to the ore pulp by means of a magnetic field generation device; accurately sorting the ore pulp by means of a classifier, so as to enable selected minerals in the ore pulp to be exposed under the action of the magnetic field in processes of rising and dropping, thus attaching to an inner wall of the concentration barrel and moving upwards until reaching a collecting area; by making the selected minerals fall into a material receiving trough of the concentrating machine in the collecting area, enabling other materials in the ore pulp except the selected minerals to enter into a tailings trough of the concentrating machine at the bottom of the inner cavity of the concentration barrel and then into a tailings conveying system.

An apparatus for separating hot particles including a plurality of materials having different magnetic properties includes a plurality of permanent magnets arranged in a magnet assembly and configured to create a magnetic flux capable of providing a coercive force on at least a portion of the particles, the magnet assembly being mounted on a stationary shaft, a moving surface proximate the magnet assembly for carrying the particles in a downward path through the magnetic flux while the coercive force attracts the portion of the hot particles toward the moving surface, the moving surface being mounted on a drive shaft supported by a bearing, and an inert gas supply system which supplies inert gas into a gap between the stationary shaft and the drive shaft for cooling the drive shaft and the bearings, and into the magnet assembly for purging the magnet assembly of oxygen.

A ferromagnetic material removing device for removing ferromagnetic material from a fluid containing ferromagnetic material is disclosed. The device comprises at least one carrier encasing a plurality of permanent magnets arranged in an inner space of the carrier. The outside of the carrier is configured to collect ferromagnetic material that is attracted by the magnets. The carrier is ring-shaped and rotatably mounted and the device comprises a removing portion arranged and configured to remove the ferromagnetic material from the outside of the carrier and a driving assembly arranged to rotate the carrier.
