. To' all whom'z't may concern I Be lhrkllOWIl that LEnrcn LANGGUTH,

. engineer, a subject of the German Emperor,

, residing at. Nee1-pelt, Belgium, have invented certain newand' useful Improvements in Electroina'gnet-ic Separators;iand I do here- ",by declare the 'followin to he a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to IQ-Whjiclr it appertains to make and use the 1 same.

This invention relates to an electromagnetic sep rator for separating'ore suspended in -wat nd comprises a stationary in- 1-5d'uetion .y, the separating surface of cuts a closed ring relatively to ltipolar system of magnets is fOwing to the rotation of the v eti'c system within or above the ring,

' niaxi'ma and minima-ot magnetic attraction are produced on its surface, while the mate rial to be separated is sin'iultaneously transferred to the induction body by means of channels which participate in the rotation. f constructionaccording to this invennon, is illustrated in the accompanying j 1rawi11gs in which, 7 Figure l is a Vertical section, and a plan. Fig, 3 is a partial plan'view of the Figs. 5 and 6 are partial views, taken insectio'n'on lines 'lV-X and Y-Z respectively of Fig. 3. I

The material to be separated pas from i a stationary feed hopper J into the rotating annular hopper L, from which outlet branches M lead to the rotating supply channels A. These channels are arranged above the four-pole rotatable magnetic tern B, and the material, falls from the channels on to the stationaryinduction ring D having a funnel-shapedinner surface.

The induction ring D is provided in a well known manner with radial grooves, tor the purpose of increasing the area of the sur face under magnetic influence.

The material passing from the channels A over the induction ring'l), is separated below the magnet poles Bin such a man .ner that the diamagnetic material is discharged, while the magnetic material remains adherent to the rin After a quar ter of a revolution the whole circumference of the ring D has been passed by the sup- Specification of Letters'Patent.

ply channels and covered With magnetic material. It is then freed from the material in question by a series of rinsing nozzles H which rotate together with the magnetic system, washing oft the'magnetic'material at the point where the magnetic attraction is a minimum at the moment. The nozzlesor ejectors H are supplied with water from an annular tank Gr, rotating with the magnets B. l 4

In' order to prevent the washed-off magnetic material from'passing into the same circular collecting channel as the diamag-i netic material discharged during the teed- 7 ing, the rotating magnetic system is provided with a conical sheet-metal tray E which is provided at points corresponding in number to the poles with recesses or outlets R, R, R The diamagnetic material 7'5 can fall through one recess R- and arrives atthe collector channel K; the washethofi' magnetic material passes through another recess or outlet B into the collector chan nel F and the medium material passes 30 through the third recess or outlet it into a central collector channel N. The material passes from the recesses or outlets ll", to the collector channels K, N, F, through chutes or spouts O, l, and Q respectively. 35

The magueti. separator desrz-ihed differs frol'n all well known devices by the scparw tion being ctl'ccted on a stationary surface, and by the magnetic iiatcrial remaining at rest on the said surface, until it is washed off by a jet oi water at the weakest magnetic point of the magnetic field. Jiny secmidarj' forces such as ('t1!llli l"'1 torce and the like, are therefore eliminatedsuch fi'i'irccs coming into pla where the separation is etiected on a rotary iu u-siion tray. 'lhez c sccoiulary forces exercise an unfavorable elicct on the separation, more particulari when suhstances which have weal; magnetic proper ties aroheing dealt \iit'u. )wiug to the suppression of the said secondary forces, and more particularly of centrifugal force, the device accordi g to this invention is speciallysuitahle ttor those bodies which have only weak magnetic properties.

The number of outer or operativepoles in this device can he Yaried as desired but when it is an even numberas shown, I pre for that adjoining operative poles have opposit-e polarities.
