. APPARATUS FOR MAGNETIC SEPARATION- Patented July 31,1906.
Application filed February 10,1ac5. Serial no. 245,030
To all w hom) it may concern;
Be it known that I, GUSTAF GABRIE V BRING, a subject of the King of Sweden and a resident of Petersfors, Jernboas. in the 5 Kingdom of Sweden, have invented certain new and useful Improvements in Apparatus [drawn by the magnetic orce toward the cen-' tend the solenold.
According to the present invention the mixture magnetic and nonma "netic grains or particles to be treated is fed into the preferably upright solenoid at the upper 0 en' end thereof, and the magnetic parti- 0 es are attracted and moved toward the center of the solenoid or ma etic field. The power of the magnetic fie d is, however, so calculated that the attracted particle's do not stop at the center of the field, but on account of their (gravity-continue to move slowly 'downwar During the movement they are subjected to the action of powerful jets of "Wflt8r','Wl1i0h carry away the non-magnetic a'in's. adhering to the magnetic particles.
3'5 inally, the magnetic particles arecarried oil firom the magnetic field throu h the lower v open end of the solenoid. T e non-magnetic -net-ic eld in the opposite direction--viz., through the upper end of the solenoid.
As all the articles to be separated. are brought into the magnetic field and exposed to ,the magnetic force for a comparatively long time, the loss of magnetic ains will be very small, even if the ains o the material .i should be onl 0.15 mi limeter in diameter, j.or still -less.- t the same time the magnetic producton account of the powerful washing to which it is exposed will become very pure-i. e., free from any admixture of non- :very powerful without incurring. the risk of washmg awa magnetic material, for the rapidity of t e current is considerably re-, 5 5 duced at the outlet by means of a funnel or other-equivalent device placed within the sled .ains-are carried oil from the mag tube '13 is accelerated by water under The solenoid should have a certain predetermined field strength, depending upon-the permeability of each particular material, as also upon the size of the sins. The former is known to be always su stantiall the same' as far as magnetites are concerne ,and thus the size of grains will, in fact, be determina- If vat a certain winding of the solenoid a current strength of, say, fifteen amperes is necessary when .thevmat-erial is crushed into grains of a diameter of 0.15 millimeter or less, then in, the ease of a size of grains of, say, one I'nillimeter the current strength should. not/exceed five to seven amperes in order that the apparatus shall work in the most favorable way.
The drawing shows a vertical section of an apparatus constructed according to this in-' :vention. I I
l'is the solenoid, consisting of an inner brass drum 2'of cylindrical, conical, or any other suitable shape. vPlaced on the said drum is awinding 3, of insulated copper wire, sald w nding being arran ed 1n any suitable way, so that the center 0 the magnetic field I either coincides with that of the inner drum or lies above or below it. The copper wire has the diameter and length necessary to give the solenoid the field strength required. At the outerside the windin is covered with a mantle 4 of sheet-iron. P aced within the solenoid is a funnel 5, forming at the top an 'annular'channel or space 6, havin an outlet 7. Within the lower part of the innel is a" perforated tube 8,-andthe perforated wall of the lower portion of the funnel is surrounded by a mantle 9, said tube and mantle being furnished with 'waterirojin the pressure-conduit 10, so that 'owerful jets of water are thus pressed into its funnel. The narrowest portion of the funnel preferably has a mouthpiece 11, whichjea'ds toadischarge 'ipe or tube 12, connected with another tu e .13, provided with an inner nozzle 14 by means of which the water passing out through the sure from the tube or 'conduit 10. Y
The apparatus works in the followin manner:- The material to be treated is'crus ed to presgrains of a size ofone millimeter and less (or still finer) and is fed through the channel and tube 15 into the funnel 5, previously filled with water. The non-magnetic grams are immediate] carried with the stream of water over the e ge of the. funnel down into the channel 6 and ,awaythrough the outlet 7.
The magnetic'particles, on the contrary,
2 Y i sealed more rapidlydown toward the middle of the solenoid, then continue to move slowly downsinks through the IIlOllthPlBGB 11, the opening of which is to be measured corresponding .to each particular ore, and finally the magnetic product is carried off through the tube 13 et of water from nozzle 14 accelerates the escape of the product from the magnetic field, if necessary, I 5
'I claim as new, and desire to secure by Let- Having now described my invention, what ters Patent, is-
1. Inapparatus for magnetic separation, a substantially upright solenoid, a funnel placed thereinadapted to contain a body of Water and perforated at its lower end, a mantle surrounding said erforated part, a tube Within the funnel and having its lower end perforated, said mantle and tube communicating with means for supplying Water under pressure.
