摘要： A rotor having at least one peripheral annular channel (24) is rotatable relative to a stator surface of a surrounding stationary housing to impel material in the channel from an inlet (28) through the housing, to a circumferentially spaced outlet (36), through which plasticised (liquid) material is discharged by pressure developed by the material being impelled against a first stationary surface (34) which projects into a channel downstream of the outlet (36). A second surface (40), upstream of the outlet (36), has a clearance with the walls of the channel (24) and restrains advance of (unmelted) material (39) in the centre of the channel while permitting liquid material (25) to be dragged towards the first surface (34). The channel space (46) between the first and second surfaces (34 and 40) enables the discharge pressure to be generated in an accumulated pool (42) of the liquid material. The second surface (40) may be provided on an extension along the channel of part of the member (32) which defines the first surface or may be provided on a further member (38), which may be of various different configurations, and may act as a scraper against one channel wall.

摘要： A multi-stage rotary processor for plastic and polymeric materials which are, or become in the course of processing, viscous liquids, including an annular housing, a rotor coaxial with and rotatable with respect to the housing and having a cylindrical surface in slidable sealing relation with the interior of the housing, a plurality of annular channels formed in the cylindrical surface and cooperating with the housing to form annular processing passages, transfer passages, which are preferably channels in the surface of the housing for cooperation with the cylindrical portions of the rotor, to provide passage for transfer of material between processing passages and blocking members extending into the channels to hold material in the processing passages for relative movement with respect to the channel walls for processing. In a preferred structure the transfer channels are formed and the blocking members may be mounted in removable flow director units including surfaces forming part of the surface of the annular housing.

摘要： Novel rotary processors and methods which provide extremely efficient devolatilization of particulate materials which contain substantial amounts of volatiles and in which the boiling point of the volatiles presents separation problems. The processors and methods involve a rotatable element carrying a plurality of annular channels and a stationary element providing a coaxial closure surface operationally arranged with the channels to provide enclosed processing passages. Each passage includes inlet means, outlet means and a channel blocking member all associated with the stationary element and arranged and adapted so that material fed to the inlet can be carried forward by the rotatable channel walls to the blocking member for discharge from the passage. The passages are interconnected by material transfer grooves formed in the closure surface and are arranged to provide at least a melting stage and a devolatilizing stage which operationally communicates with a vacuum source. In the preferred embodiment, particulate material sprayed with a devolatilization aid or carrier substance is fed to the melting stage through a vacuum hopper, melted, collected and transferred through a strand die mounted at the inlet to the devolatilizing stage. The material in the form of thin strands undergoes unrestricted flash foaming while falling a predetermined distance into the devolatilizing passage, is carried forward, collected, sheared to release the volatiles and is discharged from the devolatilizing stage.
