fabricate the screw. Tapered shaft and variable pitch Poor fabrication tolerances are a frequent problem the consequence is high power consumption and poor flow. Also, it is a quite expensive configuration. Variable pitch The minimum pitch must be no less than one-half the screw diameter (logging) , the maximum pitch approx. one screw diameter.

Short Pitch, Single Flight. Flight pitch is reduced to 2/3 diameter. Recommended for inclined or vertical applications. Used in screw feeders. Shorter pitch retards flushing of materials which fluidize.
