ABSTRACT:
An apparatus for pulverizing a collection of pieces of materials such as vulcanized rubber to create a very fine powder. The apparatus includes a piston and a cylinder which places the material to be pulverized under extremely high pressure of at least 1,000 psi and forcing the compressed material out of one or more exit ports. These exit ports are located at the end of a smoothly narrowed channel leading to the exit ports. A rapidly moving cutter is positioned so that its path completely covers the exit port. The compressible materials are thus compressed to the point where they have no voids and provide a solid incompressible cuttable face. The rapidly moving cutter creates a fine powder at the exit port.
