Flexible Screw Conveyors

The Fresco flexible conveyor is a versatile means of conveying fine powders or coarse granular materials over distances up to 12m. The flexible screw which self-centers in the middle of the outer casing by using the product as a bearing is driven from one end by a geared motor. The simple design of the conveyor means there is only one moving part (flexible screw), which is totally enclosed within the outer casing, entrapping the product and providing dust free conveying either horizontally or inclined to suit your application.

We have a full range of sizes from 55mm up to 200mm and an assortment of screws including rounds, heavy duty rounds, flats, wide flats and beveled edge, constructed from 304 stainless steel or carbon steel. Outer casings are manufactured from Ultra High Molecular Weight Polyethylene and Polypropylene. For very abrasive applications stainless steel or carbon steel outer tubes are available. Conveyor capacities up to 55m3/hr are achievable.

A flexible conveyor can convey material is any direction to bend under, over and around obstacles. Whether conveying horizontally or vertically the conveying tube and screw can be routed easily in any direction.

Flexible Screw Conveyors

Gentle conveying without segregation or degradation is achieved through screw/tube combinations matched to suit each application. The continuous mixing action created by the screw will not separate blends.

Fast, thorough cleaning is achieved by removing the lower cleanout cap and jogging the conveyor in reverse. Full disassembly can be achieved quickly, allowing for complete sanitization between product changes.
