Abstract

The invention relates to the technical field of foam recovery, and discloses an environment-friendly foam volume-reducing granulation machine and a foam volume-reducing device thereof. The first volume reduction assembly includes two first extrusions. When at least one first extrusion part rotates, the first extrusion part drives the foam positioned in the first extrusion cavity to move towards the other end of the first extrusion cavity. The two first pressing parts can jointly press the foam in the first pressing cavity. And the extruded foam gradually moves to the other end of the first extrusion cavity along with the continuous rotation of the extrusion part. In the process, the foam is compressed in the transverse direction by the co-extrusion of the two first extrusion parts, and the force of rotation of at least one first extrusion part can promote the foam to be stretched and deformed in the longitudinal direction.
