Spares and Replacement Components for Screw Conveyors Individual segments can be purchased by a customer wishing to build their own spiral or merely replace worn or damaged sections of an existing conveyor system. We can produce a regular range of spiral segments from 25mm dia to 800mm dia with any combination of pitch and centre shaft size. Larger segments up to 300mm dia can also be supplied but delivery periods for these are slightly longer than for the regular range. We also manufacture Ribbon spiral segments, these are attached to the centre shaft or tube by means of spacing pieces. This type of flighting is particularly recommended for handling sticky or damp materials, as it prevents build-up around the centre shaft or tube. Back one Page
