Short Pitch Conveyor Screw

Short Pitch conveyor screws are of regular construction except that the pitch of the flights is made less than the outside diameter of the screw.

These short pitch screws are recommended for use in inclined screw conveyors of slopes 20° and over. They also are used extensively as feederscrews, especially as the feeder portion of a uniform diameter conveyor screw consisting of a section of short pitch flights and the balance regular pitch. The crosssectional loading of the regular pitch portion of the screw thus is controlled.
