The invention relates to a crushing tool for plastic materials drivable to a rotary motion, comprising a carrier (), which can be rotated about a rotational axis (B) centrally located on it and on the surface () of which tools () 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 () a deflector () is arranged, wherein in an area of the carrier () connecting radially to the deflector () web- or strip-shaped conveyor wings () are arranged and in the area of the carrier () connecting to the conveyor wings () radially towards the edge () the tools () are arranged.

Comminuting tool

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.

Device for processing plastic material

The present invention concerns a method for processing and detoxification of a material, especially a thermoplastic material, and for removal of contaminants or impurities from this material, wherein the material is heated under vacuum in at least one receiving tank (), mixed and possibly comminuted, and wherein a rinsing medium is introduced into the receiving tank () beneath the material level, conducted through at least a partial region of the material, and the rinsing medium enriched or saturated with contaminants is brought out from the receiving tank () once more.

Method for preparing and detoxifying

Apparatus for processing plastics material

The invention relates to a process and an apparatus for the treatment of a material in the form of fragments or particles which is moved and/or rotated, mixed, heated and, if appropriate, comminuted by at least one mixing element () in a receiver or cutter-compactor (), where, in the course of the process, undesired substances which impair the treatment of and/or further operations on the material are removed from the material by introducing a gas, in particular air or an inert gas, in a region below the level of the material located in the receiver () during its operation, or below the level of material of the mixing vortex which forms within the receiver (), where the gas is forced to flow through at least a subregion of the material, and where the gas then saturated with, or with an increased concentration of, undesired substances is discharged from the receiver () in a region above the level of the material located in the receiver () during its operation or above the level of the material of the mixing vortex.
