Tapered travelling-wave electromagnetic wave concentrator

Abstract

The invention discloses a tapered travelling-wave electromagnetic wave concentrator, comprising a machine frame, a feed hopper, a tailing hopper and a concentrated ore hopper; the lower part of the feed hopper is provided with a material dividing cone which is arranged at the upper open end of a tapered linear electric motor, an electromagnetic coil is embedded in the groove of the tapered linearelectric motor, the concentrated ore hopper at the upper part is sleeved at the outlet of the upper end of the tapered linear electric motor, an ore-dividing cone is arranged at the outlet of the lower end of the tapered linear electric motor, the central tapered tailing hopper is arranged at the inner side of the ore-dividing cone, the lower concentrated ore hopper is arranged at the outer side of the ore-dividing cone. The taper travelling-wave electromagnetic wave concentrator has the advantages that the structure is simple, due to the absence of moving parts, the maintenance is very convenient; the concentrator can sort and discharge the magnetic, non-magnetic ore materials continuously; meanwhile, through the electromagnetic regulation or frequency conversion technology, the strengthof the magnetic field and the arc moving velocity of the magnetic field can be adjusted, and the sorting operation for different magnetic minerals and with different sorting speeds can be realized.

Description

technical field [0001] The invention relates to mineral processing equipment, in particular to a conical traveling wave electromagnetic mineral processing machine. Background technique [0002] At present, magnetic beneficiation generally uses permanent magnets to fix the magnetic field or electromagnetic fixed magnetic field. Under the action of the magnetic field, the magnetic ore particles are affected by the magnetic force of the magnetic field and move to the magnetic poles.

[0002] At present, magnetic beneficiation generally uses permanent magnets to fix the magnetic field or electromagnetic fixed magnetic field. Under the action of the magnetic field, the magnetic ore particles are affected by the magnetic force of the magnetic field and move to the magnetic poles. They are adsorbed on the cylinder made of non-magnetic materials, and the cylinder rotates. Movement, to separate magnetic materials from non-magnetic minerals, this kind of magnetic beneficiation equipment has a complex structure, and the maintenance of moving parts and transmission systems is relatively large

At the same time, because the magnetic poles are fixed, the magnetic field is also fixed, the minerals can only do tumbling motion on the surface of the cylinder, and the separation effect is not ideal.
