Abstract
Abstract A can crusher having a pair of horizontally aligned wheels that are in contact in rotational movement, and that receive and crush cans passing therebetween, and which wheels discharge the cans at a high velocity that causes the cans to pass into a horizontally arranged tube that intersects with an upwardly angled tube that carries air under pressure. The air under pressure and the velocity movement of the cans moves the cans upwardly in the angled tube to a container.
