摘要

The front edge (9) of the inlet opening (5) of a processing chamber (1) is hinged to a peripheral wall (3) so that the front edge can rotate with respect to a rotation axis when receiving impact from an object or material. The peripheral wall is partially or entirely made of elastomeric material.
