Abstract

An apparatus for conveying granular bulk material has two mutually meshing worms (5), the in worm grooves (5b) of which are steadily curved in profile. The pitch (h) and the width (a) of the profile of the worm grooves (5b) increase steadily in the conveying direction at least in that section of the worms (5) which is disposed between a feed opening adjacent end wall plate (13) and an outlet opening (22) for the bulk material. Thereby, the formation of lumps of bulk material is to all practical purposes avoided in operation of the apparatus. For the production of a worm (5), worm grooves are milled into a cylindrical workpiece by means of a face milling cutter arranged obliquely to the workpiece. The workpiece is rotated about its axis and during each complete revolution is displaced through a constant distance. The milling cutter is journalled in a milling head which is pivoted around a pivot axis which extends at right angles to the workpiece axis. <IMAGE>
