Patent ID: 10722901

Abstract:
The invention relates to a shredding device (1) used for picking apart compressed blocks (2) of loose-fill cellulose thermal insulation material. It comprises a chute (3) with a chute inlet (3a) configured to receive the insulation block (2). Further, it comprises a shredder (4) rotatable around a substantially horizontal axis (A), mounted at an outlet (3b) of the chute (3). The device (1) is characterized in that the rotatable shredder (4) is a cylinder with protruding grating pins (5) arranged on its mantel surface (4′), where the pins (5) have a length shorter than the radius of the cylinder and are adapted to grate, pick apart and fluff the insulation from the compressed block format (2) into a fluff material with an even density. Further, the invention relates to a method for picking apart loose-fill cellulose thermal insulation material compressed into a block (2).
