Abstract
A machine agitates and rips scrap aluminum cans to expose their interiors and shake out sand, dirt, and other material in the cans. The machine has an enclosure in which a rotatable shaft is supported. A plurality of blade sets are mounted on the shaft within the enclosure to rotate the shaft. The blade sets are distributed along the shaft and interleaved with a plurality of angled, stationary vanes that are mounted to an inside surface of the enclosure. These parts cooperate when the shaft is rotated by propelling scrap cans on a helical path on which the blade sets batter and rip the cans, throwing them against the vanes and the sides of the enclosure. As the cans are battered and agitated by the blades, their contents are emptied and the cans are ultimately propelled to a collection point.
