Scrap crushing machine

A scrap crushing machine, comprising crushing means including a crusher rotor and at least one associated anvil;

• a housing accommodating said crushing means, said housing having an inlet opening and an outlet opening, a base arranged substantially under said rotor and extending from said inlet opening to said outlet opening, and an upper cover arranged substantially above said rotor and extending from said outlet opening to said inlet opening to define with said rotor a return chamber;
• separating means arranged in said outlet opening;
• an outlet connected with said outlet opening;
• and a flap arranged behind said rotor as considered in direction of rotation of said rotor and having a separating edge, said flap being swivelable to at least one operating position in which said edge feeds sufficiently crushed scrap pieces passing through said separating means mainly to said outlet and feeds insufficiently crushed scrap pieces mainly to said return chamber, said flap being also swivelable to an open position in which insufficiently crushed scrap pieces are also fed to said outlet, said flap having two wedge surfaces which are arranged in a wedge-shaped manner and form said separating edge, and said flap being arranged so that one of said wedge surfaces from a deflecting surface leading from said separating edge to said cover in said operating position, and one of said wedge surfaces forms an ejecting surface guiding insufficiently crushed scrap pieces to said outlet in said open position, said deflecting surface and said ejecting surface being formed by the same one of said wedge surfaces, another of said wedge surfaces being formed as an ejecting surface for sufficiently crushed scrap pieces when said flap is in a closed position.
