Abstract
Abstract A portable can crusher for reprocessing cans such as beer cans and the like. The crusher includes a hopper in which a baffle (16) is provided for directing cans towards an elongate aperture (19) formed between a casing base and a driven reprocessing wheel (20). The wheel (20) has deformation means (24) on its periphery not only to compress cans fed to the aperture (19) but also to assist in the feeding of cans through the aperture. The can crusher may be trailer or vehicle mounted.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
A portable can crusher comprising a hopper into which cans to be reprocessed are received said hopper extending into a casing the bottom of which defines a base, baffle means in the casing directing cans under the influence of gravity towards the hopper base, a driven reprocessing wheel mounted in spaced relationship from the casing base so as to from an elongated aperture between said wheel and casing base, the axis of rotation of said wheel lying transversely to the flow of cans directed over the baffle means, at least one land welded or otherwise secured to the periphery of said wheel, the spacing between said at least one land and the casing base when said land is in a lowermost position being approximately 2 mm, wherein cans fed toward one side of said elongate aperture are compressed as they emerge from the other side of said elongate aperture.
