HP = Nameplate Horsepower of the motor on the screw conveyor S = Screw Conveyor Speed. The torque rating of the drive shaft, coupling shafts, coupling bolts and conveyor screw must be greater than Full Motor Torque for proper design. A 12-inch diameter screw conveyor was selected for the example.
Vertical screw conveyors are a very efficient method for elevating a variety of bulk materials at very steep inclines or completely vertical. KWS considers any screw conveyor located on an incline over 45-degrees to be a vertical screw conveyor. The compact design allows for the vertical screw conveyor to fit into almost any plant layout.
"Horsepower" is a measure devised by 19th century manufacturers of steam engines (literally "engineers") to compare the work performed by their machines with the amount more traditionally achieved using horses and pit ponies. It was determined that horses of that era could, on average, elevate a weight of 330 lbs. by a height of 100 feet, in a ...
