<p>The screw of a single screw extruder has a grooved inlet section in a feed pocket. The inlet section has a larger diameter than the screw and tapers towards the screw diameter. The inlet section (6) extends beyond the front edge (9) of the feed opening (8) by an axial distance (a) according to the relations a = 0.2s to 0.8s, k = 0.2s to 0.8s, and a+k is up to 1.4s, (where d = outer dia. of screw, s = screw pitch, and k = axial length of taper).</p> |
