Abstract
Abstract A can crusher using a pair of wheels with resilient tires that are arranged for in-line rotational movement with the tires touching. Cans are directed by a chute into the intersecting contacting area of the rotating tires, whereby the cans are crushed in passing therebetween with the speed of rotation of the tires projecting the cans with considerable force, causing the cans to move to deposit at the other end of a large container.
