Abstract: Apparatus and method of shredding cans to produce a shredded material suitable for detinning comprises a chamber having an apertured peripheral wall. A rotor is mounted in the chamber and is moved in contra rotation to the chamber. Cans to be shredded are introduced into the chamber inwardly of the rotor which is provided with impellers. The impellers serve to partly shred the cans and throw the partly shredded cans to the peripheral wall where a bed of partly shredded cans is established. A shearing action occurs in the bed as further cans are urged against the bed by the impellers and the shredded material passes through the apertured peripheral wall to be removed from the apparatus.
