Abstract

Disclosed is a grinding cylinder assembly, comprising: a grinding cylinder (11) for accommodating a material; a material box (12) connected to the grinding cylinder; an elastic film (13) located between the grinding cylinder and the material box in a natural state; and an air pressure adjusting apparatus that is at least arranged on one side of the film, the air pressure adjusting apparatus being able to form an air pressure difference on both sides of the film, such that the film can deform to cover the inner wall of the material box. Also disclosed is an oxygen-free wall-breaking apparatus comprising the grinding cylinder assembly.
