Abstract:
A system for pulverizing brittle recyclable material mixed with paper and other non-brittle debris and for separating the pulverized brittle recyclable material from the paper and other non-brittle debris, the system comprising:a pulverizing pass having a crushing plate extending therein, the pulverizing pass being configured to receive brittle recyclable material,a rotatable crusher includinga rotor shaft which is rotatably and horizontally mounted within the pulverizing pass,means for rotating the rotor shaft, anda plurality of hammers extending from the rotor shaft,wherein each hammer has two arms extending from opposing ends of the rotor shaft and each arm is coupled to a blade mounting base,wherein an impact blade extends from each blade mounting base of each hammer in a configuration to provide a close tolerance with the crushing plate of the pulverizing pass such that brittle recyclable material is pulverized as the hammers are rotated past the crushing plate, andwherein each hammer has an open section defined by the rotor shaft, the two arms, and the blade mounting base such that each hammer is substantially open;drying means for heating the brittle recyclable material, the drying means being coupled to the pulverizing pass in a configuration such that the brittle recyclable material is dried in the pulverizing pass before being pulverized; andmeans for separating the pulverized brittle recyclable material from the paper and other non-brittle debris by size.
