Screw Conveyors - Custom-Built By A Specialist Manufacturer

Screw conveyors are used within industry primarily to move large quantities of solid or semi-solid materials efficiently. The screw conveyor, sometimes called an auger conveyor, has been used in materials handling for many centuries, possibly even dating back to ancient times. Allegedly conceived by the Ancient Greek engineer, physicist and inventor Archimedes, it is thought by some historians that this kind of device was used to provide water through an irrigation system to the Hanging Gardens of Babylon. Nowadays, while the basic design remains relatively unchanged, the applications are many and sophisticated. From food processing to injection moulding, from the oil field to agriculture, the screw conveyor is a valuable and essential mechanism in industry.

Screw Conveyors Supplied for Bulk Materials Handling

Screw Conveyors

For transportation and bulk materials handling, the Archimedean screw can claim to be the most successful time-tested and versatile workhorse in industry. The screw conveyor has been developed to serve as wide an application band as is likely to be met for powders, meals, pellets and granular materials. Screw conveyors are commonly used for general movement and distribution of bulk materials as well as bulk intake, silo discharge and hopper discharge applications. In general, most free-flowing powders, grains and pellets as well as many semi-free flowing materials, can be conveyed or discharged with an Archimedean screw system. Material flow rate can be controlled by varying the screw conveyor flight design, speed and percentage loading.
