  • Patent number: 4177954
    Abstract: A rotor is mounted rotatably in a housing. A plurality of hammer cylinders are rotatably mounted on the rotor and are radially spaced from the axis of rotation of the rotor as well as being equidistantly circumferentially spaced from each other. Hammer cylinders crush concrete to be recycled against a plurality of breaker cylinders which are yieldably mounted for protection against ingestion of uncrushables. The rotatable mounting of the various cylinders insures that a fresh surface will continuously be presented in order to spread the wear due to impact over the entire surface of the cylinder.
