Auger Conveyors. An auger conveyor (or screw conveyor) consists of a helicoid screw rotating within an enclosed tube or open U-tube (Fig. 3.7 ). Its invention is credited to Archimedes (287-212 BC) who used it to pump water from the holds of ships ( CEMA, 2003 ). With only one moving part in contact with grain,...

Screw conveyors move materials either horizontally, on an inclined or vertically. They are used to feed, distribute, collect or mix and can be equipped to either heat or cool while performing this transfer. They are widely used in grain & oil, feed, food, metallurgy, mine, plastic, chemical engineering, building and medicine industries.

This paper is concerned with the design criteria of screw feeders: a non proper design and selection of this device, which is present in large part of industrial processes, could mean poor performances, excessive power, severe wear of plant and degradation of the conveyed material.
A screw conveyor consists of a circular or U-shaped tube which a helix rotates. Grain is pushed along the bottom of the tube by the helix; thus the tube does not fill completely. Screw conveyors are widely used for transporting and/or elevating particulates at controlled and steady rates.
Sep 27, 2015· INTRODUCTION OF SCREW CONVEYOR • Screw conveyors are widely used for transporting and/or elevating particulates at controlled and steady rates. • They are used in many bulk material applications in industries ranging from industrial minerals, agriculture (grains), pharmaceuticals, chemicals, pigments, plastics, cement, sand, salt and food processing.
best conveyor design. Since the Screw Conveyor selected is based on a maximum volume control of material to be handled, surge loads, overloads and choke feeding must be accounted for in the conveyor design. Screw feeders are popularly used for this control and are discussed in other pages of this catalog. CLASSIFY YOUR MATERIAL
A screw conveyor with the housing diameter of 15.5 cm, screw diameter of 13 cm and screw shaft diameter 3.5 cm having the length of 150 cm was constructed for conducting the experiments.
Screw conveyor. They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a " shaftless spiral ", driven at one end and free at the other. The rate of volume transfer is proportional to the rotation rate of the shaft.
