Bulk materials handling by Screw Conveyors or Auger Conveyors

Auger Screw conveyor

The Screw Conveyors are also known as Auger screw conveyor, which works on the principle of moving the materials from one place to another. They are the basic equipment for bulk material handling. A screw conveyor works on the mechanism that uses a rotating helical screw, called auger screw conveyor flights, that is installed within a tube or trough, to move liquid or granular materials.

Auger screw conveyor parts 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 called a solid shaft screw. Other types are open helix or shaftless screws driven at one end and free at the other.

The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications, the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process.

Application of Screw conveyor

Industrial application of Screw conveyors are often used horizontally or at a slight incline, providing movement. They are capable of moving semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, etc.

The screw conveyors are economical as well as, can be accommodated in small space, allows, utilizing an inclined screw conveyor for elevating or say conveying material. The angle of inclination as per the rule of thumb is 45 degrees or less, otherwise, the material will end up falling backward over the flighting and not conveying to the desired destination.

Screw conveyors are versatile and one of the most reliable cost-effective to convey a wide variety range of bulk material from dry free-flowing to wet sluggish dewatered biosolids.

Screw auger conveyor designed to operate in any  positions, whether horizontal or vertical. properly designed serve the purpose for many years to come uninterrupted, increasing the productivity
