Flexible Screw Conveyors Move Virtually Any

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
