<p>The production screw consists of different zones consisting of a single-turn or double-turn feed zone (L2) of core diameter (D3), a compression zone (L3), a metering zone (L4) of core diameter (D4), and a decompression zone (L5) of diameter (D5), these being followed by a shearing section (L6) having inlet and discharge channels, with an overflow flank or flanks which can have different widths and diameters according to the materials to be used. The shearing zone (L6) is followed by a mixing zone (L7) consisting of a plurality of rings having suitable grooves. The pitch (S1, S2) and the slope angle ( alpha 7) are likewise determined by the raw material to be used. <IMAGE></p> |
