Abstract
The invention relates to a device for processing material by mixing and/or plasticating, comprising at least two conical screws () which are arranged next to each other in a common screw casing () and the flights of which engage with one another and are driven to rotate in the same direction of rotation about the respective screw axis () by at least one motor, with the material that is to be processed being fed to the screws () through at least one feed opening () in the screw casing () which is arranged in the feed zone (E) of one end face of the screws (), and with the material that has been processed by the screws () leaving the screw casing () through at least one outlet opening () in the screw casing () that is arranged in the discharge zone (A) of the other end face of the screws (). In order to provide advantageous plasticating conditions it is proposed that the ratio of the numerical values of the screw outside diameter (c, d) to the profile overlap, i.e. to the overlapping area of the two screws (), both in the feed zone (E) and in the discharge zone (A) is in the range of between one to one and one to two.
