Abstract
A rotary shredder apparatus for reducing paper material having weight characteristic that creates difficulties in feeding the material for reduction, and in which the apparatus embodies an adjustable slide sheet having one position to allow bulky material to impact on reduction rotors by exposing a significant circumference of the rotary shredder, and another position reducing the exposed circumference of the shredding rotor so that light weight material can be drawn into the shredding rotor with the least amount of rotor fan effect generated on such material.
