FLEXICON® Flexible Screw Conveyors

Move Virtually Any Bulk Material

Free-flowing and non-free-flowing materials and blends

FLEXICON® Flexible Screw Conveyors

Flexicon flexible screw conveyors (also known as helix conveyors, screw conveyors, spiral conveyors and auger conveyors) offer efficiency and versatility, conveying bulk materials ranging from large pellets to sub-micron powders—both free-flowing and non-free-flowing—with no separation of blended products.

FLEXIBLE SCREW
FLEXIBLE SCREW

Rugged flexible screw is
the only moving part
contacting material,
moving free-and non-free-flowing materials that tend to pack, cake or smear, with no separation of blended products. It is driven above the point at which material is discharged, preventing material contact with bearings or seals. Small to wide diameter screws in many geometries handle low to ultra-high capacities.

 
STANDARD AND HIGH-FLOW HOPPERS
STANDARD AND
HIGH-FLOW HOPPERS

A wide range of standard and high-flow hoppers is available to feed the flexible screw conveyor's charging adapter.

PROMOTION DEVICES

A variety of vibratory (shown) and mechanical hopper flow promotion devices is available to move non-free-flowing material into conveyor charging adapter.

 
EFFICIENT DRIVE SYSTEM

DISCHARGE ASSEMBLY

The flexible screw conveyor discharge end can be suspended on chain or cable, attached to a ceiling support, or affixed to process equipment or the rim of a vessel.

Flexible Screw Conveyor

Mobile and custom configurations

All Flexicon flexible screw conveyors are available on caster-mounted frames with conveyor support masts for in-plant mobility, reducing the need for multiple stationary units.

Both mobile and stationary units are readily customized using interchangeable screws, conveyor tubes, drive motors, hoppers, flow-promotion devices, sensors, controllers, and other components to satisfy the most diverse and demanding end-use requirements.
