Abstract
1421549 Screw conveyers HOECHST AG 28 Dec 1972 [31 Dec 1971 17 Nov 1972] 59774/72 Heading B8A [Also in Divisions B1 and B5] Apparatus for mixing soda lye and pulverized cellulose into a moist crumbly form includes a screw conveyer having a compression section 10 wherein the cross-sectional area between the screw conveyer and its housing decreases in the direction of feed, the housing in this section having an internal thread 11 running in the opposite sense to that of the screw and having a smaller pitch than that of the screw. The decrease in cross-sectional area may be achieved by conically tapering the housing and/or screw (Figs. 2, 3) in or against the direction of feed. The material is extruded as a compacted annulus 12 which is acted upon by a plurality of blades 14 to produce the crumbly form. The material may be fed to the conveyer by a horizontal screw 4. The conveyer and its housing may comprise discrete feed 5, compressing 10 and end 13 sections, the conveyer parts being mounted on a common shaft 21. The latter may be hollow to accommodate heating or cooling mediums. Various dimensions of the apparatus are given.
