Abstract:
A substantially horizontally disposed drum is supported for rotation. One end of the drum is adapted to receive lumps of material which are granulated within the drum by abrasive particles which are projected from an abrasive throwing wheel. The drum includes a plurality of apertures through which the granulated material and abrasive particles are removed and subsequently conveyed to a separator for separating the granulated material from the abrasive particles. The apparatus may include a conditioner which scours the granulated material.
Abstract:
In an apparatus for conditioning a granular matrial, a centrifugal throwing wheel projects the material radially against an impact surface which completely surrounds and is spaced from the periphery of the wheel. An air stream is moved between the impact surface and the periphery of the wheel so as to remove contaminants from the projected particles.
Abstract:
A continuous cleaning apparatus includes an elongated barrel which is open at both its feed and discharge ends to permit parts to flow axially therethrough. Cleaning devices are positioned along the barrel to clean the parts as the barrel rotates and a pickup apparatus is disposed at the feed end to insert the parts into the barrel.
Abstract:
An abrasive blast cleaning system includes blast means for granulating and scouring the sand removed from a no-bake mold whereby the sand is reconditioned for reuse in a subsequent nobake molding operation.

Abstract:
In a workpiece treating arrangement, a drum has an elongated member extending through the upper portion thereof for supporting a throwing wheel within the interior of the drum for treating workpieces during rotation of the drum.
Abstract:
In an apparatus for granulating molded sand, the feed material including lumps of molded sand from a first conveying surface are discharged onto the upper section of an endless conveyor which moves the material through a stream of abrasive particles and discharges the granulated sand and accumulated abrasive particles on a second conveying surface.
Abstract:
Wustite scale is removed from iron or steel products by blasting fine grit from a centrifugal blast wheel which rotates at low speed, against the product at an angle thereto with the grit having sharp edges.

Abstract:
A workpiece treating apparatus includes a slatted barrel for holding the workpieces during rotation of the barrel. A draw bar is disposed generally parallel to the barrel slats and has workpiece engaging pawls thereon. The draw bar is mounted for oscillatory movement and for rotational movement about its own axis so that the pawls can engage the workpieces and pull them forward in the barrel and can then be disengaged from the workpieces whereby the pawls may return to their original position.
