Patent number: 10525479Abstract: The invention relates to a crushing tool for plastic materials drivable to a rotary motion, comprising a carrier (1), which can be rotated about a rotational axis (B) centrally located on it and on the surface (3) of which tools (4) for the processing and crushing of the plastic materials are arranged. It is provided according to the present invention, that in the area of the rotational axis (B) of the carrier (1) a deflector (5) is arranged, wherein in an area of the carrier (1) connecting radially to the deflector (5) web- or strip-shaped conveyor wings (6) are arranged and in the area of the carrier (1) connecting to the conveyor wings (6) radially towards the edge (7) the tools (5) are arranged.Type: GrantFiled: January 21, 2015Date of Patent: January 7, 2020Assignee: EREMA ENGINEERING RECYCLING MASCHINEN UND ANLAGEN GESELLSCHAFT M.B.H.Inventors: Klaus Feichtinger, Manfred Hackl, Peter Pauli, Georg Weigerstorfer

Patent number: 10173346Abstract: Disclosed is a device and a method for processing plastic material with at least one receiving container, wherein at least one mixing and/or comminution tool, rotatable about a rotation axis, is arranged, for mixing and warming the plastic material, and with at least one conveyor for discharging the plastic material from the receiving container, with at least one screw rotating in a housing, where the conveyor is connected, at its material inlet side via an opening which is formed in a side wall of the receiving container, with the interior of the receiving container. An imaginary extension of the central longitudinal axis of the conveyor extends, against the conveyance direction of the conveyor, past the rotation axis of the receiving container, without intersecting this axis, where the longitudinal axis of the conveyor is offset by a separation relative to the radial ray of the receiving container on the discharge side.Type: GrantFiled: December 10, 2015Date of Patent: January 8, 2019Assignee: EREMA ENGINEERING RECYCLING MASCHINEN UND ANLAGEN GESELLSCHAFT M.B.H.Inventors: Georg Weigerstorfer, Klaus Feichtinger, Manfred Hackl, Gerhard Wendelin
