I have several screw conveyors in my plant all running at different speeds. I need to increase the speed of a screw conveyor due to increased capacity. All my drive units are Dodge TA II shaft-mounted gear reducers utilizing belts and sheaves between the motor and gear reducer. How do I calculate the current output speed of a screw conveyor?
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 quite so precise in screw feeders; so it is always
