Abstract A machine for comminuting glassware or the like into small, rather uniform particles, which employs an upstanding disintegration chamber having an entrance in the upper portion for receiving the material to be comminuted. Within the lower portion of the chamber and extending transversely thereof is mounted a high speed rotary comminutor mechanism which comprises a plurality of sets of rigid comminuting elements or bars disposed radially and sequentially on a common axis of revolution. The elements of each set extend in axially spaced relation and are successively angled differentially. Adjacent elements of each set preferably are of somewhat different lengths so that their disintegrating tips or extremities lie in different orbits of revolution. The said rotary comminuting mechanism per se disintegrates the bottles, containers, glassware or stiff plastic without the use of statinary grate bars or other shearing elements, and the disintegrated particles with preferably the assistance of a deflection medium are dropped by gravity and collected in a drawer or other collection medium which is readily removable from the machine for periodic dumping of the collected particles. With my improved structure, material such as frangible bottles and other containers may be comminuted into particles of average size of less than one half inch in longest dimensions.
A machine for rather uniformly comminuting frangible material such as bottles, glassware and plastic, having in combination, an upstanding, disintegrating chamber with a receiving opening in its upper portion and having a discharge area at its lower end for directing comminuted particles with the aid of gravity to a collecting medium, a high-speed rotary comminuting mechanism mounted transversely in the lower portion of said chamber above said discharge area and substantially traversing said discharge area and comprised solely of a multiplicity of generally radial rigid comminuting elements disposed in circumferentially and axially spaced relation on a common axis of revolution, said comminuting elements being of at least two different lengths and terminating in interspaced, individual ''''bite tips, '''' the tips of the shorter lengths being interspersed substantially uniformly with the tips of the longer elements to provide a generally cylindrical assembly for comminuting said materials, said tips being axially angled in succession at acute angles to the adjacent tips thereof, said chamber having a side declined from the vertical to form a chute for guiding frangible material downwardly, said chamber being completely unobstructed in the portion above said rotary mechanism, and means for revolving said comminuting mechanism at high speed in a direction where said elements move from the upper portion of their orbits towards and downwardly of said chute-forming side, thereby ''''biting out'''' substantially uniform particles without using shearing action or effect.
