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.
FLEXICON® Flexible Screw Conveyors
Move Virtually Any Bulk Material
Free-flowing and non-free-flowing materials and blends
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.
Material discharges from flexible screw conveyor below point at which it is driven, preventing material contact with seals.

PROMOTION DEVICES
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
Low horsepower motors, simple gear reducers and ultra-efficient operation significantly cut energy cost per volume of material conveyed.
SECURING THE
DISCHARGE ASSEMBLY
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.
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.
