Abstract
An impactor for breaking large, boulder size, ferrous metal pieces comprises a massive, horizontally axised, cylindrically shaped rotor having spaced apart, outwardly extending, impact heads. The rotor is formed of a number of axially aligned, thick, large diameters disks that are secured together face to face. Deep notches formed in the circumferential edges of the disks provide head mounting pockets within which inner portions of the heads are received. Each of the heads has an outer portion which projects radially outwardly of the rotor and has a small impact area. Large metal pieces are gravity fed, down a chute, into the paths of rotation of the heads impact areas, below the horizontal axis of the rotor. The pieces are struck by the downwardly moving head impact areas to momentarily receive an enormous concentrated force resulting from the rotation of the rotor mass. The forces imparted by the impacts break the metal pieces and pulverize inclusions, such as slag, rocks and the like, and fling the small broken pieces away from the rotor for subsequent collection and removal.
