DESIGN AND SIZING OF SCREW FEEDERS - TUM
In fact, the operating torque is usually 60-65% of the nominal torque of the motor in screw conveyors, and even lower in screw feeders. However, it is impossible to decrease the motor size as it will be unable to start. This is why the sizing done in accordance with the C.E.M.A. standards is quite reliable in screw conveyors; however, it is not ...
