Method and device for separating all nonmagnetic components from a mixture of scrap metal in order to obtain pure scrap iron

摘要

A process and a device for dry separation of a conglomerate of metal scrap of non-magnetic particles from magnetic ones. Dry separation equipment for metal scrap which have a sequence of magnets placed in line, the poles of which are north-pole to south-pole are unable to meet this requirement. This insufficiency is due to the fact that the conglomerate of metal scrap is not sufficiently shook. This procedure does mean that at the end of transportation there is still non-magnetic material and other stuff fixed to the magnetic material. Intensive motion necessary is achieved by this invention by locating magnets adjacent to one another with equal poles, north-pole to north-pole and south-pole to south-pole and so on.

1. A device for dry purifying of a conglomerate of metal scrap from non-magnetic stuff comprising:
a conveyer belt; and a plurality of magnets arranged in a row over the conveyer belt; wherein the conveyer belt is configured to transport comminuted metal scrap along the plurality of magnets in a transportation direction of the conveyer belt; and wherein a side of the conveyer belt facing the comminuted metal scrap is rugged; characterized in that poles of each magnet of the plurality of magnets are arranged such that a north-pole of each magnet is followed by a north-pole of a next magnet of the plurality of magnets and a south-pole of each magnet is followed by a south-pole of the next magnet, wherein the next magnet is the magnet of the plurality of magnets adjacent to each magnet in the transportation direction.
