Abstract

La présente invention concerne de manière générale un dispositif de broyage (10). Le dispositif de broyage (10) comprend une première rangée de disques de coupe (14) montée sur une première circonférence, et une deuxième rangée de disques de coupe (18) montée sur une deuxième circonférence. La deuxième rangée de disques de coupe (18) est décalée par rapport à la première rangée de disques de coupe (14) dans une direction longitudinale du dispositif de broyage (10), et la deuxième circonférence est disposée par rapport à la première circonférence de telle sorte que la deuxième rangée de disques de coupe (18) fait saillie au moins en partie radialement vers l'extérieur depuis la première rangée de disques de coupe (14). Par conséquent, les première et deuxième rangées de disques de coupe (14, 18) coupent un matériau à enlever à une profondeur différente, une distance prédéterminée (X) étant formée entre les coupes afin d'obtenir une ligne de broyage sensiblement continue.
