ABSTRACT:
An apparatus for comminuting bulky objects, especially vehicle tires and parts of automobile bodies, comprises two parallel shafts arranged for rotation in opposite directions and at different speeds, each shaft being driven by a separate hydraulic motor and provided with comminuting rings alternately axially staggered with respect to one another on each of the shafts. The rings are provided with means including sharp, pointed portions for seizing and comminuting the objects while conveying them through interstices defined between adjacent rings on the shafts and by smooth portions of the shafts themselves. The shafts comprise a number of alternately disposed grooved bearing surfaces and smooth surfaces constituting the smooth portions. The rings are formed of a number of ring-elements, each in the shape of a sector of an annulus and having a grooved, concave, cylindrical inner surface engaged with a portion of a grooved bearing surface. The ring-elements of each ring are interconnected by high-strength screws. The ring construction enables the rings to be very firmly secured to the shaft which bears them and at the same time enables the rings-elements to be changed without difficulty.
