With variable pitch, every pitch increases in length in the inlet section creating more available volume for addition of bulk materials from the hopper. With stepped pitch the flight pitch changes in increments. For example, a stepped pitch screw feeder may have 2feet of 1/3 pitch, thenSCREW CONVEYOR.  — OCW  UC3M,–Sectional screw conveyor. –Single cut flight. –Ribbon flight. –Standard pitch with paddles. –Screw cut and folded flight. –Single flight short pitch. –Van paddle conveyor. –Single tapered flight standard pitch. –Step flight. –Single flight variable pitch. –Single flight large pitch. –Double flight standard pitch.
