Flexible Screw Conveyor: Move virtually any bulk material
:: 03 January, 2009
Free-flowing and non-free-flowing materials and blends
Flexicon flexible screw 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.
For moist, sticky, friable or other difficult-to-handle materials that pack, cake, smear, plug or break apart see BEV-CONTM flexible screw conveyors.
Only one moving part
The only part contacting material in a Flexicon flexible screw conveyor is the rugged flexible screw which is driven by an electric motor. As it rotates, the screw propels material and self-centers within the conveyor tube, providing
constant clearance between itself and the tube wall.
This simple design does not require cables, chains, disks, internal bearings, and numerous moving parts found in bucket elevators, rigid augers, drag chains, and/or aeromechanical conveyors—parts that can add initial cost, require maintenance, wear out, breed contamination, and/or break down.
Convey in any direction
Whereas many conveyors (such as rigid screw conveyor, bucket elevator, drag chain conveyor and aero mechanical conveyor designs) have limited angles of incline and/or straight-only conveying paths, Flexicon flexible screw conveyors can move material vertically, horizontally, or at any angle—over, under, or
around obstructions, through small holes in walls or ceilings.
Gentle product handling and blending
Flexicon flexible screw conveyors can handle your products gently, because the flexible screw self-centers as it rotates. This can provide ample clearance between the screw and tube wall to prevent grinding, crushing, and other product
In addition, the gentle rolling action created by the screw prevents the separation of blends throughout the entire length of the conveyor.
Flexible screw pioneers
Flexicon matches an unequalled number and type of standard and custom flexible screws to a correspondingly wide selection of hopper designs and charging adapters to meet all of your material and process parameters with the
greatest efficiency and reliability.
Perhaps no other manufacturer has advanced the application of the flexible screw conveyor as far and as fast as Flexicon—the first to introduce 4 1/2inch (115mm), 6 inch (150mm), and 8 inch (200mm) diameter screw/tube combinations
that elevated the capacity of this category of conveyor more than 10-fold in an 8-year period. After more than 10,000 installations worldwide involving a gamut of bulk materials, Flexicon has amassed a wealth of performance data on flexible
screws—many of which have been engineered, machined and formed to Flexicon specifications. To you, it means that Flexicon has most likely solved your problem in the most efficient and cost-effective manner possible—or can do so as
a matter of routine.
