MAGN ETlC SEPARATO R.
SPECIFICATION forming part of Letters Patent No. 402,904, dated May '7, 1889.
Application filed July 31,1888. Serial No. 281,496. (No model.)
To all whom it may concern.-
Be it known that I, GURnoN CONKLING, a
citizen of the'United States, residing at Glens Falls, in the county of WVarren and State of New York, have invented new and useful Improvements in Magnetic Separators, of which the following is a specification.
This invention relates to certain improvements in magnetic separators, as set forth in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 represents a plan or 'top view of part of aseparator. Fig. 2 is a section in the plane 00 as, Fig. 1. Fig, 3 is a section in the plane 2/ a Similar letters indicate corresponding parts.
In the drawings, the letter A indicates a frame, in which are mounted three pairs of rollers, B B, B B B B carrying a series of aprons, O C 0 in such positions relatively to each other that the material discharged from the first apron, 0, drops upon the second apron, O, and if more than two aprons are used the material from the second apron, 0',
drops upon the third apron, O and so on. A-
hopper, G, serves to feed materiak-such as comminuted iron ore-onto the apron O.
D E F are aprons which travel over rollers H in a direction at right angles to the aprons O O O and in close proximity to the same. In the interior of each of the transverse aprons D E F are arranged magnets I, in proximity to those parts of said transverse aprons which are near to the conveying-aprons O 0 C respectively. The magnets I can be permanent magnets or plates magnetized by the electromagnets K. .As the iron ore passes beneath the transverse apron D a portion of the iron particles is attracted by the first magnet I and caused to adhere to said apron while the remaining ore is discharged upon the second apron O, and carried by the same beneath the transverse apron E, and as it passes beneath said apron the magnet I in this apron also attracts a quantity of iron particles, causing the same to adhere to said apron E. The same operation is repeated as the remaining ore passes beneath apron F, The waste discharges from the conveyor-apron G into the receptacle R, while the iron particles are collected in receptacle N, one of which is shown in Fig. 2. Brushes L secure a separa tion of the iron particles from the transverse aprons, and chutes M serve to carry said iron particles into the receptacles N.
The shafts of the rollers H can be rotated by securing thereto pulleys O, and belts P may communicate motion to the pulleys Q, communicating with the rollers B B B By having a series of conveying-aprons, C 0 O and a corresponding series of transverse aprons, D E F, the operation of separating iron particles from non-magnetic parts can be carried on until the waste which discharges from the last of the conveying-aprons is practically free from iron, since any iron particles which should have escaped the at traction of the magnets of the apron D will be caught by the attraction of the succeeding magnets. Various grades of separation can also be attained by having the different magnets of varying intensity, By having, for instance, the magnet of the apron D of very slight intensity, so that its attractive power is weak, only pure iron particles will adhere to the apron D. By having the magnet of the apron E of greater insensity said magnet will attract iron particles, to which adhere, or which are surrounded by, objects not by themselves attracted by the magnet. By having the magnet of the apron F of still greater intensity it will attract iron particles containing still more matter not by itself attracted by the magnet. By placing the conveyingaprons one above the next, as shown, the Waste of the first apron in being discharged upon the next apron is spread and turned over, so that the iron particles which on the first apron may have been covered up will be brought on the top and exposed to the action of the magnet on the next apron.
IVhat I claim as new, and desire to secure by Letters Patent, is
1. The combination, with a series of 0011- veying-aprons running in the same direction, one above the next, as shown, of a series of transverse aprons, magnets secured in proximity to each of the transverse aprons, and suitable driving mechanism for actuating the aprons, substantially as described.
2. The combination, with a series of conveying-aprons running in the same direction, In testimony whereof Ihave hereunto set my one above the next, as show1no'f a like series hand and seal in the presence of two subscrib- T0 of transverse aprons, a magnet secured in ing' witnesses.
)lOXiIllit to each of the transversea )rons the t 1 T y 1 5 inagnets gr the different transverse a prons be- GURDON IXLING' ing' of different intensities, and suitable driy- \Vitnesses:
ing mechanism for actuating the aprons, sub- "W. O. I'IAUFF,
stantially as described. E. F. KASTENI-IUBER.
