Abstract: A rotary tumbler metal reclaimer includes an inner cylinder and a concentric outer cylinder that rotate simultaneously. The inner cylinder includes a first compartment that intakes material for breaking by teeth, a second compartment that receives broken material from the first compartment and crushes the material into smaller particles and a third compartment wherein particulate material enters the space between the inner cylinder and the outer cylinder by attrition through perforated screens. The second compartment includes a crusher having various features for crushing lump material as it rotates. The third compartment provides further breakage and conveyance of particulate material. Particulate material then returns proximate the intake for screening into fine and coarse sizes and then collecting for reuse. Metallics and metallic oxides exit the tumbler through apertures in the rear of the third compartment for collection. The tumbler reclaims metals, metallic oxides, sands, and other materials for reuse.

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

Abstract: A two-way vibratory conveyor includes at least one trough mounted on a base and a drive which reciprocally moves the trough(s). The conveyor, which in one embodiment has two interconnected troughs and in another embodiment has a single trough, includes a drive which uses a single motor. In the two-trough conveyor, the two troughs are driven in opposite directions. In the single-trough conveyor, the single motor is used to selectively drive the trough in one of two opposite directions. The troughs are mounted to a base using springs and stabilizer arms. The stabilizer arms, which are made of ductile iron, have been found to be withstand larger loads and have a longer useful life than currently available stabilizer arms.

Abstract: The present invention relates to a rotary lump crusher/reclaiming drum for reclaiming lump materials such as aggregates, chemically-bonded sand lumps, dross, ferrous and non-ferrous scrap and slag. The rotary drum has an outer cylinder concentric with an inner cylinder both of which rotate simultaneously, the latter containing treatment compartments to reduce the lumps to smaller pieces which are in turn reduced to reclassifiable particulate matter in preparation for resuage.

Abstract: A retaining rod is provided for forcing a tight interfit between adjacent segments of a liner of a casting shake-out unit, sand reclaimer, rotary media drum, or a tumbling unit. The adjacent edges of the liner segments have triangular grooves which combine to create diamond shaped channels between adjacent segments of the liner. The rod is generally diamond shaped in cross-section and tapered from front to back, giving the rod an overall trapezoidal appearance. The cross-sectional height of the rod is greater than the cross-sectional width of the rod. Thus, the rod can be placed in the channel in one of two positions and the same rod may be used if the clearance between adjacent segments is large or small simply by rotating the rod 90.degree..

Abstract: A casting shake-out unit has an outer cylinder and an inner cylinder. The inner cylinder is made of a plurality of interfitting segments which interlock and cooperate with each other to prevent a segment from falling out of the completed inner cylinder. Each segment includes tongues extending from opposing edges of the segment's body and pockets formed in the body. The pockets of one segment receive at least a part of the tongue of a neighboring segment.

Abstract: A tumbling mill includes an inlet area, an outlet area, and a tumbling area between the inlet and outlet areas. The mill is formed as a tri-cyclical member having an outer cylinder extending along the tumbling and outlet areas, and an inner cylinder concentric with the outer cylinder and extending through the inlet, outlet and tumbling areas. The inner and outer cylinders define a space therebetween. The inner cylinder is perforated to allow sand to fall into the space between the inner and outer cylinders. The inner cylinder includes an inner helical vane to urge sand, media, and castings toward the outlet area, and an outer helical vane to urge sand and media toward the inlet area. A reclassifying screen is provided in the inlet area to classify sand. Sand particles that are sufficiently small passes through the screen and out a chute. Sand particles that are not small enough are recirculated through the tumbling mill to be further broken down.
