An apparatus for pulverizing vulcanized rubber and rubber products includes an ovoid rotor housed within a casing whereupon during rotation of the rotor, and/or the casing, the rubber material is subjected to various cutting and shearing forces. Additional means may be provided for periodically altering the clearance between the rotor and casing whereby the grinding effects can be enhanced, and still further means may be utilized to alter the clearance in a different manner whereby in addition to being subjected to cutting and shearing forces the material also undergoes a crushing operation.
