Abstract: Can crushing apparatus wherein mutually angularly disposed convex and flat conical disks are rotated to define an open, wedge-shaped receiving region which progressively diminishes about a circular locus to an exit position of close adjacency of the surfaces. Cans are introduced into the receiving region whereupon they are progressively longitudinally flattened, thus facilitating the expulsion of any liquids remaining within the cans while carrying out flattening. By introducing cans from an upwardly disposed trough structure, inherent safety is achieved such that the operator cannot reach into the crushing components of the apparatus. The slope of the disk member engaging surfaces preferably is about 9.degree., while the included angle therebetween at the receiving region preferably is about 33.degree.. By operating the disks at about 60 rpm, improved silent operation is achieved.
