ABSTRACT:
An impact crusher includes a crushing chamber, a rotor mounted in the crushing chamber, and an apron having an impact surface, said apron being movably positioned within the chamber. The apron is pre-loaded to oppose forces generated within the crushing chamber. The apron is free to move away from the rotor in the event that the forces generated within the chamber exceed a predetermined threshold. During normal use, the apron is suspended within the chamber against a mechanical stop, and the apron is free to return to its initial suspended position after the removal of uncrushable material from the chamber.
