MAGNETIC SEPARATING APPARATUS.
Specification of Letters Patent.
Patented June 29, 1915..
Application filed February 1, 1913. Serial No. 745,657.
To all whom it may concern falls upon the upper s Be it known, that I, EDWARD H. Rornnn'r, a citizen of the United States, residing at Leavenworth, in the county of Chelan and State of Washington, have invented new and useful Improvements in Magnetic Separating Apparatus, of which the following is a specification.
My invention relates to certain new and useful improvements in apparatus for separating magnetic particles from the nonmagnetic gangue with which they are intermixed, and particularly to an appartus'for use in the concentration of magnetite and other magnetic ores.
The primary object of my invention is to provide an apparatus combining in a single and simple structure means for subjecting the ore to two consecutive separating actions, whereby after the first separation of the magnetic particles from the non-magnetic particles a second. separating action may be, carried out to final y separate the magnetic particles from the non-magnetic particles which become entangled with the magnetic particles and are carried therewith past the first point of separation.
A furdier object of the invention is to provide a construction of apparatus by which the second separating action is rendered more positive and certain than at the first stage of separation or than is possible with the magnetic separators of the type heretofore employed.
The invention consists of the features of construction, combination. and arrangement oi parts hereinafter fully described and claimed, reie being had to the accompanying drm 'whicl:.:
Figure l a p plan iew of the separator. Fig. 2 is a longitudinal section showing the feed of the material.
In carrying my invention into practice, I provide a suitable frame structure 1 which is supported a hopper 2 containing the crushed 011e, said hopper being provided at its lower a d with an outlet 3 and a feed roll 4, to facilitate and regulate the discharge of the teria The material dischr ed from the hopper .otch of a feed belt 5 which passes at its inner end around a nonmagnetic pulley 6, which may be of any ordinary type, and at its outer end around a larger pulley or rotating magnet 7, the armature lam nations of which are preferably of soft iron. The upper horizontal stretch of the belt 5 travels in a direction toward the pulley 7, and as the material comes within the magnetic field of said pulley or rotating magnet, the magnetic particles are attracted and held against the belt and pass therewith around said pulley, while the free non-magnetic particles drop by gravity from the belt and discharge via a primary waste chute 8.
Arranged in'longitudinal alinemcnt with the primary separator consisting of the belt 5, pulley 6 and rotating magnet 7 is a second separator consisting of a belt 9, non-magnetic pulley 10 and rotating magnet 11. This second separator is arranged in longitudinal alinement with and in the same horizontal plane as the primary separator and its parts are correspondingly arranged with relation to each other, the upper stretch of the belt 9, however, moving in a reverse direction to the upper stretch of the belt 5. Arranged below the said two separators is a transmission or feed belt 12, the upper stretch of which is movable in the opposite direction to the direction of movement of the upper stretch of the belt 5, but in the same direction as the upper stretch of the belt 9. This belt 12 passes around suitable pulleys'13, and 14, and is designed to receive the magnetic particles passing beyond the magnetic field of the rotating magnet 11. The magnetic particles thus fed forward by the belt 12, on coming within the magnetic zone of the rotating magnet 11, areattracted by said magnet and jump up ward and .are held in cont ct with the belt 9, by which they are positively and effectually freed from the non-magnetic particles left combined therewith from the first separation, which non-umgnetic particles pass forwardly around the pulley 14 and drop by gravi ,y upon a second waste chute 15 by which they are discharged, while the magneticpmitioles taken up by the belt 9 are carried forwardly and around the pulley and discharged upon a concentrates chute '16.
(in the shaft carrying the rotating magnet 11 is a driving pulley 17 adapted to receive power from. a suitable-source, whereby the conveyer 9 is positively driven. This drive shaft is in turn connected at one side of the frame by a crossed belt 18 with the shaft of the rotating magnet 7, whereby said magnet and the belt 5 are driven in an opposite direction to the magnet 11 and belt 9, and at the opposite side of the frame is a belt 19 connecting the drive shaft with one of they shafts of the conveyer 12, whereby said conveyer is driven in the proper direction. A belt 20 connects the shaft of the rotating magnet 7 with the feed roll 4, whereby said roll is driven at the desired rate of speed.
. It will be observed that while the upper stretches of the belts 5 and 9 are horizontal, the lower stretches of said'belts are inclined to the horizontal by reason of the size and arrangement of the pulleys 6 and 10, whereby the said lower stretches of the belts 5 and 9 are brought close to the upper stretch of the belt 5 at the points where they pass around vthe rotating magnets 7 and 11, and thence are gradually spaced from the belt 12 as they recede from the respective magnetic fields. This arrangement obviously facilitates the deposit of the magnetic particles resulting from the first separation onto the belt 12, the taking up of said particles by the rotating magnet 11 and belt 9 and the discharge of the non-magnetic particles or waste material from the belt 9. It will also be observed that by the described construction and arrangement of the second separator, the magnetic particles are caused to physically detach themselves from any nonmagnetic particles left remaining therewith, whereby a positive and certain final separation is secured, resulting in a highly elii- V cient and absolutely cleanly concentrating act1on.
I cla1m:--- A magnetic separator comprlsing a pair of primary and secondary separator belts arranged in the same horizontal plane, each of said belts having upper horizontal stretches movable in opposite directions from their relatively inner ends and lower stretches inclined in opposite directions from the relatively outer to the relatively inner ends of the belts, guide pulleys around which the inner end of the primary separator belt and the outer end of the secondary separator belt pass, rotating magnets of larger diameter than said guide pulleys and forming pulleys around which the outer descending end of the primary belt and the inner ascending end of the secondary belt pass, a hopper arranged .to feed material to the upper stretch of the first-named belt, a conveyer arranged beneath said primary and secondary separator belt and having a horizontal stretch movable in the same direction as the horizontal stretch of the secondary belt and the secondary belt and the associated rotating-magnet, chutes leading from the outer ends of the respective separator belts, and a chute leading from the delivery end of the conveyer belt.
In testimony whereof I aflix my signature in presence of two witnesses.
EDWARD ROTHERT.
