Difference between revisions of "Screw Conveyors"

Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases.

Augers are also used to force food products through dies to produce pellets. These are then processed further to produce products such as bran flakes. Augers are also used in oil fields as a method of transporting rock cuttings away from the shakers to skips. Augers are also used in some types of pellet fed barbecue grills, to move fuel from a hopper into the firebox in a controlled manner. Augers are often used in machining, wherein the machine tools may include an auger to direct the swarf (scrap metal or plastic) away from the work piece.
