Abstract: An apparatus includes first and second conveyor structures with first and second conveyor surfaces. The conveyor surfaces face each other and are arranged to define a comminuting space in the apparatus. The apparatus brings the conveyor surfaces in movement in the direction from a first end of the conveyor structures towards a second end of the conveyor structures, and the two conveyor surfaces are placed to face each other. The conveyor surfaces are additionally placed in a convergent manner so that the gap between the conveyor surfaces narrows in the movement direction of the conveyor surfaces. The advancing movement of the conveyor surfaces brings about compression in material being comminuted. The conveyor surfaces are in a double-converging so that in addition to the convergence in the movement direction, the conveyor surfaces are additionally convergent in the transverse direction in relation to the movement direction, the comminuting space thus also being double-converging.

Abstract: The invention relates to an apparatus for comminuting of material. The apparatus includes a first conveyor structure with a first conveyor surface, a second conveyor structure with a second conveyor surface, and in which apparatus the first conveyor surface and the second conveyor surface are set facing each other. The conveyor surfaces are arranged to define a comminuting space in the apparatus, The apparatus has means for bringing the conveyor surfaces in a movement in the direction of movement D where the two conveyor surfaces placed to face each other are arranged to move from a first end of the conveyor structures towards a second end of the conveyor structures. The conveyor surfaces positioned to face each other are placed in a convergent manner so that the gap between the conveyor surfaces narrows when examined in the movement direction of the conveyor surfaces, so that the advancing movement of the conveyor surfaces is arranged to bring about compression in the material being comminuted.

Abstract: An apparatus for comminuting of material that includes a first conveyor structure with a first conveyor surface, a second conveyor structure with a second conveyor surface, and in which apparatus the first conveyor surface and the second conveyor surface are set facing each other. The conveyor surfaces are configured in a double-converging manner so that in addition to said convergence in the movement direction, the conveyor surfaces are additionally placed in a convergent manner so that the gap between the conveyor surfaces also narrows in the transverse direction in relation to the movement direction, such that the comminuting space becomes double-converging.

Abstract: The invention relates to an apparatus for comminuting of material The apparatus comprises a first conveyor structure (CI) with a first conveyor surface (B1), a second conveyor structure (C2) with a second conveyor surface, and in which apparatus the first conveyor surface (B1) and the second conveyor surface (B2) are set facing each other. The conveyor surfaces (B1, B2) are arranged to define a comminuting space (GS) in the apparatus, The apparatus has means (MIA, M2A) for bringing the conveyor surfaces in a movement in the direction of movement D where the two conveyor surfaces (B1, B2) placed to face each other are arranged to move from a first end (E1) of the conveyor structures towards a second end (E2) of the conveyor structures.
