Abstract
A comminuting device for commercial or industrial waste in the form of paper, plastics and the like comprising a downward feeding hopper, having a rotary cutting mechanism associated with a bottom discharge opening and a crushing and conveying tool above and rotating with the rotor has the discharge opening aligned substantially vertically to pass centrally or chordwise through the lower region of the hopper and the rotor is equipped at its circumferential face with knives disposed one above the other to travel through a substantially cylindrical cutting area traversing the discharge opening.
Claims18
A comminuting device for comminuting commercial or industrial waste material, comprising a receiving container having a generally vertical axis, said container having an upper portion for receiving the waste material to be comminuted and a lower portion formed at least partially with a conical configuration, said lower portion also having a discharge opening for discharging the comminuted waste material, a rotor means rotatably mounted in said container for rotation about a substantially vertical axis, cutter means driven by said rotor means and disposed juxtaposed to said discharge opening for comminuting the waste material and discharging the comminuted waste material out through said discharge opening, and breaking and conveying plate means rotatable with said rotor means within said conically configured lower portion of said container above said discharge opening, said breaking and conveying plate means being operable to precomminute said waste material and to exert a downward conveying action of the waste material being comminuted, said breaking and conveying plate means having an approximately elliptical configuration and being disposed at an acute angle relative to the vertical axis of said rotor.
