Abstract: A belt assembly for an overhead magnetic separator has a belt having an inner face and an opposite outer face and a pair of opposite ends one of which is cut away on the inner face and the other which is cut away on the outer face so that the cut-away portions can normally be lapped against each other to form the belt into an endless loop of substantially uniform thickness. The belt further is formed at the other end on the inner face with a shallow transverse inner groove. Respective flat inner and outer nonmagnetic strips engage the respective faces of the belt at its lapped ends with the inner strip lying in the groove. A plurality of nonmagnetic threaded studs fixed in the inner strip project through the lapped belt ends and through the outer strip and respective nonmagnetic nuts on the studs bear on the outer strip and clamp the lapped belt ends between the strips. A layer of elastomeric material is provided on the inner strip generally level with the inner belt face.

Abstract: A high intensity field magnetic separator for separating materials of different magnetic properties, in which the materials to be separated from each other are during the movement of containers comprising induction poles and containing the materials to be separated passed through high intensity magnetic fields which are induced in the interior of coreless magnetic coils.
