I kinds or grades of magnetic material can be exactly regulated.
' intersects the direction oftravel of-the confalls behind the pole 0 into a chute The magnetic material is carried over and beyond this chute by the cylinder 6, andithe several kinds or grades of magnetic material then .fall from the cylinder in the reverse order to their attraction .by it, that is to say, the lowermost and least magnetic layer falls first, and so on; the several kinds or grades fall separately down the chutes g, h, z, and are collected separately.
In order to distribute the falling of the material'over a long path, an extension k projecting beyond the edge of the lower pole I can be provided on the upper pole as shown; If this extension is composed of lamellae g, Fig. 8, adjustable independently of each other in an arm A, the falling of the several Instead of employing the surface of rotary hollow cylinder to convey the attractedmagnetic material, anyv other appropriate conveying device may be employed the principle underlying the invention may for instance lie-adapted in the case of separators in which the conveying device is a traveling band 0, see Fig. 6, or a ring 1), rotating around a vertical axis.
lVith reference to the graduated or stepped magnetic field, it may be' remarked that hitherto the division of the magnetic field into zones of magnetic strength has usually only been adopted in the case of separators in which the direction of travel of the material under treatment,
'veying surface; in such cases however the width of track oi the material to be treated '15 generally limited because itor the greater part of this. width the magnetic material that has been attracted-during travel of the conveying surface over the first part of the width, has to be carried over material that has still to undergo attraction. The adoption of zone formation in separators of the feed'o'f material, and means for feeding the material to'be separated into the gap, means for increasing the strength of the field in steps and then decreasing the same in the same direction of feed, and means for separately collecting the grades progressively released from the traveling member. 1

A. magnetic separator of the kind set forth, comprising upper and lowerstationary poles, a, traveling member moving through the field gap, and means for feeding the material to be separated into the gap beneath and in the same direction as the traveling surface of said member moves across the magnetic field, means for dividing said field into sharply defined adjustable zones of strength increasing in the direction of feed,
said zones extending transversely of the di rection of feed,me ans for subsequently de-- creasing the field strength in the same direction, and means for separately collecting the di'l'l'erent grades of material as released from the traveling member.
