Abstract

A multi-directional tumbling cylinder for use in concentrating or cleaning of products, wherein the tumbling cylinder is of length, the cylinder mounted upon a base, is rotated through the operations of a motor, with the cylinder capable of turning in a clockwise or counterclockwise direction. The cylinder has an intake end and an outlet, and a series of liner segments disposed therein, that interconnect together to form an inner cylinder, and the segments have a series of rifling provided upon the inner surface, and series of vanes formed upon their outer surfaces, with the riffling and vanes having sloped lateral edges, at select degrees, to provide for controlled movement and volumetric flow of product being processed, either towards the outlet, tumbled within its midsection, moving product back towards the inlet, for regulated processing and cleaning of such product. An entrance vane provides for the prompt or slower movement of castings into the cylinder for processing during its operation.

Abstract

A tumbling unit such as a casting shake-out unit, rotary media drum, sand reclaimer or the like includes a cylindrical outer shell (3) and a cylindrical inner liner (5). The inner liner (5) is formed of a series of interfitting segments (9). The segments (9) each have an inner surface, an outer surface, side edges (17), a front edge and a back edge (19), and two vanes (21) extending from the outer surface. The side edges (17) of the segments (9) have a groove (25) and the grooves (25) of neighboring segments (9) define a channel between the segments (9). A pin (27) in the channel urges the neighboring segments (9) apart to form a tight interfit among the segments (9) in a row of the liner (5). The pin (27) conforms in shape and size to the cross section of the vanes (21), and align with the vanes (21) of the adjacent segments (9) to form a continuous spiral upon the outside of the liner (5).
