Abstract
An apparatus for producing shredded aggregate from, e.g., boards of expanded polystyrene, is described. The apparatus includes a shredding box defining a shredding chamber; a rotor housed in the shredding box; means for driving the rotor; a plurality of saw blades coupled to the rotor in linear succession, each saw blade having a plurality of spaced apart teeth, each successive saw blade being coupled to the rotor such that its teeth lie about halfway between the teeth of an adjacent saw blade; receiving means in the shredder box for receiving material to be shredded; and take-away means coupled to the shredder box for removing shredded material from the shredding chamber. Low density (e.g., 0.4-0.5 pcf loose bulk density) material having a uniform particle size distribution over time can be economically produced.
