A device for the preparation of plastics material, in particular thermoplastic plastics material, has a receiving container (1) for the material, the interior of the receiving container (1) having tools (21) provided therein which are arranged on a carrier disc (9). The tools are driven by a shaft (4) for rotation about the, in particular vertical, axis (8) of the shaft (4). At least one screw (17) is provided for the removal of the material out of the receiving container (1). The screw housing (16) has a feed opening (27) which is connected with respect to flow to a discharge opening (15) in the container (1), which discharge opening (15) is situated at a lower level than the carrier disc (9) and the tools (21) carried by it. Further moved tools (12), which convey the material into the discharge opening (15), are provided in the receiving container (1) below the carrier disc (9). The carrier disc (9) comprises at least one aperture (36) which connects the space (26) above the carrier disc to the space (10) below it, in order to divert water vapor and/or gaseous substances out of the space (10). The apertures (36) are situated close to the axis (8) and close to the trailing edges (37) of the tools (21) during the rotation of the carrier disc (9).
A device for the preparation of plastics material, in particular thermoplastic plastics material, with a receiving container for the material to be treated, the interior of the said receiving container having tools provided therein which are arranged on a carrier disc and which are driven by a shaft inserted onto the interior for rotation about an axis of the shaft, and with at least one screw for removing the material out of the receiving container, wherein a screw housing has a feed opening which is connected with respect to flow to a discharge opening in the receiving container, which discharge opening is situated at a lower level than the carrier disc and the tools carried by it, and wherein further moved tools which convey the material into the discharge opening are provided in the receiving container below the carrier disc, wherein the carrier disc comprises at least one aperture which is situated close to the axis and close to trailing edges of the tools during the rotation of the carrier disc and which connects a space above the carrier disc to a space below it.
