CHARLES JOHN REED, OF ORANGE, NEW JERSEY.
ORE- SEPARATO R.
SPECIFICATION forming part of Letters Patent No. 466,515, dated January 5, 1892. Application tiled April 6, 1891. Serial No.387,863. (No model.)
To all 'whom it may concern.-
Be it known that I, CHARLES JOHN a citizen of the United Orange, in the county of Essex and State of New Jersey, have made a new and useful invention in the Art of Ore-Separating, of which the following is a specification.
My invention relates to improvements in ore-separatin g machines in which a hollow revolving drum acts in conjunction with moving external magnets, gravity, and a current of air or water; and it has for its object the REED, States, residing at mixtures of powdered minerals, particularly magnetic particles from non-magnetic particles. I attain this object by the utilization of the mechanism illustrated in the accompanying drawings, and described in the specification which follows.
Referring now to the drawings, Figure l is 6, said magnets being in sectional view taken through machine, showing one `of the operating-magnets in elevation. Figs. 3 and 4 are end viewsof modified forms of the drum, showing in the one instance projections and in the other grooves on the inner surface.
Y Fig. 5 isa side elevational view of a modified form in which permanent magnets supplant the electro-magnets shown in Figs. l and 2 and in which a brush is illustrated for removing-the magnetic particles from the poles of the magnets. Fig. 6 is a detail elevational view of the rotary brush shown in Fig. 5, one of the magnets being shown in elevation.
Like letters of reference represent like parts Wherever they occur throughout the specification and in the drawings..
D is a hollow revolving drum, preferably cylindrical inform, revolving in supports O and receiving its motion from a pulley R and belt B3, connected to asource of power. (Not shown.) jy
H is a hopper or feed-box into which the powdered mixture is fed.
F is a frame Work or support to which the apparatus is bolted or secured, and is adapted connected during the a current of air or water passes into the inteward the bottom.
C represents the magnetic particles or concentrates, and Q the non-magnetic particles or tailings.
m m represent electro-magnets in Figs. l and 2 and permanent magnets in Figs. 5 and both instances attached to a belt B, which passes over pulleys -6o P P, revolving in the direction indicated bym the arrows, so that the magnets adjacent to the drum moveupward as the pulleys P carry the beltBcontinuouslyforward. These magnets m have curvilinear pole-pieces, as shown in Figs. 2 and 6, adapted to lie in close prox- ,imity to the outer surface of the revolving drum D, but not in actual contact therewith. In Figs. 1 and 2 I have shown electro-ma"- nets in which the coils are connected through 7o side supports by conductors w and brushes b with a pair of side conductors S S, insulated side of the drum by the support O and end of these side conductors S 1s connected toone pole of a dynamo-electric machine or electric battery and the other to the remaining pole thereof, said source of electrical energy7 not being shown, and the arrangement of these electro-magnets, as sh own 8o in Figs. l and 2, is such that as the pulleys P rotate in the direction indicated by the arrows the electro-magnets will be thrown into multiple-arc circuit with the conductors S and the generator to which said conductors are 85 time that theirp are passing from the bottom of the drum D to the upper support K. (See Figs. l and 2.)
T, Figs. l and 5, represents a tube connected directly to the hopper H and extending into 9o the drum D, its function being to'convey the. powdered mixture into the interior of said drum. The interior surface ofthe drum D is preferably of a roughened nature, grooves or projections being provided, as shown in Figs. 3 and 4. This particular feature, however, of a rotary drum with a roughened interior surface constitutes the subject-matter of a separate application filed by mein the United States Patent Office on the lst day of Decemroo ber, 1890, and serially numbered 37 4,246. The drum D is thus roughened on the interior for the purpose of facilitating the agitation of the powdered mixture.
In the modified form shown in Figs. 5 and G permanent magnets m are used in place of electro-magnets m in Figs. l and 2, and the magnetic particles or concentrates are removed by a rotary brush I5', journaled at the lower end of the machine and rotated by the same source of power which rotates the p ulleys P and drum D.
B2 B2 are side brushes fixed permanently to the supports O O', adapted to remove the magnetic particles from the side faces of the magnets m.
M, Fig. I, represents another means for removing the magnetic particles or concentrates when used either with electro-magnets or permanent magnets. It consists of a broad belt of leather or other analogous material, and is supported at one end by the drum D and at the other by a pulley. (Not shown.) A considerable portion of this belt projects past the end of the drum, so that as the magnetic particles, are carried forward by the magnets and o'ii't of the end of the drum they are directed toward the belt, which is moving in such a direction as to carry them to one side, so that as they pass the end of the cylinder and finally out of the inliuen-ce of the magnets they drop off under the influence of gravity, or may be swept off by a broom or in any other manner which will readily suggest itself to those skilled in the art.
"he operation of the apparatus is as fol` lows: Referring first toFigs. l and 2,the drum D is caused to rotate in either direction about its axis through the agency of the belt B3 and pulley R'. A blast of air or current of water is passed through the drum from the top to the bottom, entering from tube A. At the same time the iinelypowdered mixture of magnetic and non -m agnetic particles is passed from the hopper H by its own weight through the tube T into the interior of the revolving drum D. The rotary motion of the drum keeps the mixture thoroughly agitated, while the magnets m, which are being rotated in the direction of the arrows by the pulleys P, are being magnetized as the brushes b ride forward in contact with the two side con iductors S S, connected to the dynamo, and hence continuously attract the magnetic particles in an upward direction, so that while the drum is rotated continuously the tailings Q are passing downward and at the same time the magnetic particles or concentrates are being successively advanced in an upward direction, until they finally pass out at the top and are attached by their magnetic indu ence direct-ly to the poles of the magnets. This action continues to carry them forward until the brushes l) pass oft' the side conductors S, when the magnets are demagnetized and the concentrates fall by their own weight into the box It. It will thus be observed that in the practice of my improved method the separation offmagnetic from less magnetic or `do I limit myself to the kind or nonanagnotic particles is accomplished by the magnetic action thereof through the agency of moving magnets which move in one direction, while the non-magnetic particles are continuously advanced in the other direction through the agency of an air-blast or stream of water, the magnetic particles always passing out of one end of the drum,while the nonmagnetic particles pass out at the other end thereof. The rotary motion of the drum serves to agitate the mass and facilitate the separating action due to the aforesaid opposing forces. The quality of the separation, therefore, depends upon the relative strengths of these two forces, and theymay be adjusted by varying the strength of the magnetic field, the force of the current of air or water, and the position of the apparatus. By inverting the apparatus, for instance, or what amounts to the same, by reversing the motion of the magnets and the direction of the interior current, we have gravity and the magnetic iields acting together and against the current.
I do not limit myself to any particular position of the apparatus, as it may be operated in an inclined position at any angle from the horizontal to vertical. Nor am I limited to the particular form of magnets shown in my drawings, nor to any particular method of attaching or carrying the magnets or magnetic fields, nor to any particular direction of motion of said magnets or magnetic Iields, nor quality of interior current used, as I may use a current of nitrogen or other inert gas, or a solution of salt would serve equally as well as air or water. In other words, I desire it to be distinctly understood that my claims hereinafter made are directed, broadly, to any apparatus which will effect the separation of magnetic from non-magnetic particles by giving to the combined mass of magnetic and non-magnetic particles an advance and a rotary motion, and simultaneously subjecting the same to the influence of a moving magnetic field, which moves in a reverse direction to that of the moving mass of particles in the manner described.
That I claim, ters Patent, is-
