Abstract: Apparatus for surface cleaning of workpieces by blasting comprising an elongated rotatable cage having longitudinally spaced rings through which the workpieces are conveyed axially, while they are being blasted, by means of oscillating arms extending between the cage rings and engaging the workpieces.

Abstract: A horizontal drum-type magnetic separator for granular feeds of magnetic and nonmagnetic materials utilizing a drum rotatable about an axis of rotation into which granular feeds are infed. A magnetic field is created as by a plurality of magnets disposed about the outer periphery of the drum. A first chute is provided within the drum for collecting the nonmagnetic material as the granular feed passes through the magnetic field and a second chute is provided for collecting the magnetic material after the granular feed passes through the magnetic field.
