Definitions

  • ABSTRACT A plurality of spaced conveyors containing stationary magnets are sequentially arranged to remove ferromagnetic particles from a mixture of said particle and refuse that are initially transported to a position below the first conveyor containing a magnet in its lower run.
  • a blower directs air blasts along the path of transport to assist in the separation.
  • the mixture of iron particles and non-iron particles is presented to a magnetic field in such a way that the iron particles are drawn into it, weereas the non-iron particles are presented with the possibility of separating from the iron particles and falling away.
  • This step is affected by permitting the contaminated iron falling from a first magnetic belt to fall past a second magnetic belt rising almost vertically. The iron components are collected on the belt and the remaining refuse components fall away from the iron under the influence of their own weight.
  • the separation of the iron components from the non-iron components can be facilitated by the use of a directed stream of air.
  • a second stage of separation by means of an air stream can be arranged; this is effected by the use of the nearly-vertical magnetic conveyor belt to transport the partially-cleaned iron to a collection point. At this point the iron falls off the belt and can be subjected to a transverse air stream to remove the remaining contaminants.
  • the drawing shows the magnetic conveyor belt and the air blowers used to effect the separation between iron and non-magnetic components in refuse.
  • the conveyor associated with the magnet 5 carries the now-nearly clean iron particles to a higher level from which the iron particles fall through a shaft 9 into a container 10.
  • the particles are once more subjected to the effect of an air stream llll supplied by a second blower.
  • the air stream which is essentially horizontal in direction, tends to remove any last traces of contaminants still clinging to the iron particles. Such traces as are removed are carried through a shaft 12 by gravity and fall to the conveyor 6 which removes the particles from the system.
  • the air stream in the shaft 12 is vented through the louvres 13.
  • the special advantage of the present process lies in the fact that the separation between the iron and noniron components is essentially complete, as a result of which the value of the iron scrap thus obtained in substantially increased.
  • Apparatus for separating ferromagnetic particles from a mixture of said ferromagnetic particles and non-ferromagnetic particles comprising a first conveyor for transporting the mixture in a first direction;
  • a belt conveyor having a lower run upwardly spaced from said first conveyor and extending in a direction transverse to said first direction with one end of said lower run transversely spaced from said first conveyor; a magnet arranged over said first conveyor spaced from said one end of said lower run and closely adjacent to that face of said lower run of said belt conveyor which faces away from said first conveyor so that the ferromagnetic particles and some of the non-ferromagnetic particles clinging thereto will be lifted by said magnet onto said lower run and transported on the latter in said transverse direction out of the influence of the magnetic field of said magnet so that the lifted particles will fall freely along a curved path from said one end of said lower run; a further belt conveyor having an upwardly moving run spaced from said magnetic field and said curved path; and magnet means located closely adjacent that face of said upwardly moving run which faces away from said curved path so that the ferromagnetic particles will be attracted by said magnet means while falling along said curved path and be deflected out of said curved path against said upwardly moving run
  • Apparatus as defined in claim 2 and including means for directing a stream of air in downward direction onto the particles freely dropping along said curved path.
  • Apparatus as defined in claim 4 and including receiver means for receiving the stream of dropping ferromagnet particles and guide means for guiding the deflected non-ferromagnetic particles away from said receiver means.
