US 2019/0118189 A1 · APPARATUS AND METHOD FOR COMMINUTING OF MATERIAL

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. The conveyor surfaces positioned to face each other are placed in a convergent manner so that the gap between the conveyor surfaces (B1, B2) narrows when examined in the movement direction (D) of the conveyor surfaces, so that the advancing movement of the conveyor surfaces is arranged to bring about compression in the material being comminuted. In the invention, the conveyor surfaces (B1, B2) 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 convergent manner so that the gap between the conveyor surfaces (B1, B2) also narrows in the transverse direction (TD) in relation to the movement direction, said comminuting space (GS) thus becoming 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 has means 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 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 on the material comminuted,

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 convergent manner so that the gap between the conveyor surfaces also narrows in the transverse direction in relation to the movement direction, said comminuting space thus becoming double-converging.

A method for comminuting of material, in which method:

material including material particles is moved by means of 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 the material particles are comminuted when examined in the movement direction in a converging comminuting space between the conveyor surfaces so that one or more daughter particles are formed from the material particle by comminuting with the aid of the compression created by the moving conveyor surfaces, wherein said conveyor surfaces defining said comminuting space, in which method the comminuting space is also convergent when examined in the transverse direction in relation to the movement direction, the converging conveyor surfaces stopping, between the conveyor surfaces, the falling movement of such a daughter particle formed in the comminuting space, after which with these still moving conveyor surfaces, a movement into the movement direction is also achieved for one or more daughter particles.
