Screw Conveyors Design Data . No machinery design is complete without considering its usage. A conveyor that will be used intermittently for two hours a day does not have to be built as heavily as one that will operate twenty-four hours per day. Likewise, shock loads will affect the consideration given on gauge of steel used as well as drive equipment. Treatment of these factors and their
