Definitions

  • the invention deals with a rocess f or the magnetic separation of cru e material of various size of, grains..
  • 1n d Aconformity with its-peculiarity could'only be' adapted toa special' size of grains, or, if only one separ tor is working, the various sizes-of ,grains had to be treated on same, one after another.
  • the former process makesit necessary to provide several separators increasing thereby considerably the cost-price and the costs of runnlng the plant.
  • the second process requires after the kinds of grains have been separated a single treatment of each size of grains,' one after another. -It must then be kept in'vie'w) i, e., -for drum-separators rotating at uniform speed of themoved separatingsurfacethat each kind of grains drops o or is thrown oif at a special angle. vItl would therefore 'eitherbe necessary to adjust especially for each kind of grains the catching devices for the material, or the speeds of rotation Y of the separating surface, or both. .It .is
  • the several partition wa s a very pure separation' of. the 'magnetic and of' the non-magnetic material can be attained.
  • a ⁇ feeding' table (for common use) provided with two or more table surfaces laced one below another.
  • Each of said tabJ e surfaces with the exception of the width of mesh of said screens decreasing Vfrom top tol bottom.
  • All table surfaces are provlded with guiding mechanisms (discharge ends) which arel directed in such a Wa of .grains wandering: over t e several tablesurfaces .are charged side by side on Athe separating surfaces.
  • This can also be arwa that the spouts of the table-surface disc arges are at 'various distances from the vertical axial centreline of the .drum-separator, in order to be able when e., g. treatino two diierent .sizes ,of

  • Fig. 7 is a side elevation of a further 4modified form of the magnetic separator shown in Fig. 1.
  • Fig. 8 is a front view thereof
  • Fig. 9 is a plan view thereof.
  • the crude material yis charged on an oscillating table fitted with two table surfaces 'aand b arranged one below the other.
  • the crude material drops in the first in'- stance into the upper table surface a which is transformed into screen c at the charging-spot.
  • the two streams of material wander across the table surfaces a and b to separating drum cl.
  • the guiding mechanisms (discharges) e f the two currents of material are conducted in such a way that they reach the separating surfaces of drum d side by side.
  • the partition walls g and I are povidedfor the purpose of separating the magnetic and the non-magnetic stuff.
  • the drum d is graduated so that the separating rings are of different diameter. The coarser material will thus be fed to the separating surface z' while the finer material will be fed to the surface la, as explained.
  • each partition wall being placed in special bearings and being adjustable. According to Figs. 2, 3 and 4vonly an adjustment by he di is provided. But the rotary partition walls 'can likewise be adjusted in another manner by themselves or including their rotary axis.
  • Each partition Wall can e. g. be arranged to slide in guide-arms located on the rotary axis or a second sheet arranged to slide on the main sheet may be provided for lengthening each partition wall.

  • the axle p is journaled in a bearing r and is rockable in said bearing upon the loosening of the set screw, as shown.
  • the bearing 7' at the same time is slidable transversely to the axis of the drum in a slot provided in its associated base plate upon the loosening of bolt s.
  • the separation into sizes of grains may of course be attended to beforehand so that these are then conducted side by sideto the separatin drum, sol that the screens onv the upper ta 1c surface can be dispensed with.
  • the sifting and delivery device 1 consists of the superimposed table surfaces 2, 3, and 4.
  • Each of the table. surfaces 3 and 4 is provided with a sieve 5 and 6 respectively.
  • the two sieves are of different sized mesh. From the three table surfaces 2, 3, 4 chutes 7, 8, 9 lead tothe separating surfaces 10, 11, 12, so that three different streams of material can be simultaneously but separately separated by the magnetic separator. The material to be separated is dumped upon the sieve 6 of the uppermost table-surface 4.
