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.

An apparatus for comminuting of material, the apparatus comprising 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 and the conveyor surfaces thus being arranged to define a comminuting space in the apparatus, and which apparatus is configured to bring the conveyor surfaces into a movement in a movement direction where the conveyor surfaces facing each other are arranged to move from a first end of the conveyor structures towards a second end of the conveyor structures, and in which apparatus the conveyor surfaces set facing each other are set in a converging manner so that a gap between the conveyor surfaces narrows in the movement direction of the conveyor surfaces so that the advancing movement of the conveyor surfaces is arranged to bring about compression on the material comminuted in a convergence in the movement direction,
- wherein in the apparatus the conveyor surfaces are in a double-converging manner so that in addition to said convergence in the movement direction, the conveyor surfaces are additionally placed in a further converging manner so that the gap between the conveyor surfaces also narrows in a transverse direction in relation to the movement direction, said comminuting space thus becoming double-converging, and
- wherein the first and second conveyor structures facing each other are configured such that the transverse direction in relation to the movement direction of the conveyor surfaces is substantially vertical.
A method for comminuting of material comprising:
- moving material including material particles via the movement of conveyor surfaces of opposing conveyor structures of a comminuting apparatus into a movement direction in a comminuting space between the conveyor surfaces, and
- by conveying the material particles further and further in the movement direction, comminuting the material particles in the movement direction in a converging comminuting space between the conveyor surfaces so that one or more smaller particles are formed from the material particle by comminuting with a compression created by the moving conveyor surfaces,
- wherein said conveyor surfaces defining said comminuting space, in which method the comminuting space is also convergent in the transverse direction in relation to the movement direction, the converging conveyor surfaces stopping, between the conveyor surfaces, a falling movement of such a smaller particle formed in the comminuting space, after which with the moving conveyor surfaces, one or more smaller particles move into the movement direction, and
- wherein the conveyor structures facing each other are configured such that the transverse direction in relation to the movement direction of the conveyor surfaces is substantially vertical.
