ABSTRACT:
A scrap crushing machine comprises crushing device including a crusher rotor and at least one associated anvil, a housing accommodating the crushing device, the housing having an inlet opening and an outlet opening, a base arranged substantially under the rotor and extending from the inlet opening to the outlet opening, and an upper cover arranged substantially above the rotor and extending from the outlet opening to the inlet opening so as to define with the rotor a return chamber, separating device arranged in the outlet opening, an outlet connected with the outlet opening, and a flap arranged behind the rotor as considered in direction of rotation of the rotor and having a separating edge. The flap is swivelable to at least one operating position in which it feeds sufficiently crushed scrap pieces passing through the separating device mainly to the outlet and feeds insufficiently crushed scrap pieces mainly to the return chamber, the flap being also swivelable to an open position in which insufficiently crushed scrap pieces are also fed to the outlet.
