Custom-Built Screw Conveyor Manufacturer

Screw Conveyors Supplied for Bulk Materials Handling

For transportation of bulk materials, the Archimedian screw can claim to be the most successful time tested and versatile work horse 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 Archimedian screw system. Material flow rate can be controlled by varying the screw conveyor flight design, speed and percentage loading.

G&H Engineering have a long established reputation for quality and speed of delivery on fabricating & supplying screw conveyors, whether its complete machines, component parts or individual spares.

Standard sizes are available from stock, whilst specials, such as larger sizes or stainless steel conveyors are easily accommodated in our flexible design and build facility in Edinburgh. We fabricate bespoke screw conveyor systems to your specific requirements.
