Abstract
An apparatus is for crushing at least one of a plurality of metal cans having a predetermined diameter and a predetermined length less than about twice the predetermined diameter. The apparatus includes a pair of cylindrical rollers mounted for rotation in opposite directions about parallel horizontal axes with a predetermined distance therebetween. Each of the rollers has a predetermined roller diameter greater than four times the predetermined diameter of the can. An array of extensions on the cylindrical surface of each of the rollers extends a predetermined height from the cylindrical surface and is separated from adjacent extensions on the cylindrical surface to cause the extensions of the array to cover less than ten percent of the cylindrical surface to allow general alignment of and positioning of the metal cans therebetween. The predetermined distance between the horizontal axes of the rollers is greater than the predetermined roller diameter and less than the predetermined roller diameter plus the predetermined height. As a result, the array of extensions cause the cans to generally align with the cylindrical surface of the rollers and to be retained in alignment therewith as the cans pass between the rollers and are primarily crushed between facing portions of the cylindrical surfaces of the rollers.
