The first type of screw conveyor was the Archimedes' screw, used since ancient times to pump irrigation water. They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "shaftless spiral", driven at one end and free at the other. The rate of volume transfer is ...
Sometimes, screw conveyors feature a spiral blade, but no shaft. In this case, they are called shaft less screw conveyors, and the blade is driven at one end and free at the other. Benefits. Benefits of screw conveyors include: gentle material handling and mixing, system speed and efficiency, low investment costs and system durability.
Screw Conveyor Components. Screw conveyors transport liquid or bulk materials. They have a helical screw blade, or auger, that rotates to move granular materials along the conveyor line horizontally or at a slight incline. The auger sits in a tubular housing to keep materials in the conveyor.
Coupling shafts connect two screws together. End shafts support the end conveyor section. Coupling bolts connect shafts to the screw. End-shaft seals prevent material contamination and discharge. End-shaft bearings support the end of the shaft and help the screw rotate. Bearing hangers mount inside the trough.
Conclusion on Shafted Screw Conveyors vs Shaftless Screw Conveyors. Screw Conveyors are a standard "go to" in wastewater treatment plants in both shafted and shaftless forms. Both designs have their pros and cons, and the final choice typically comes down to what material the screw conveyor conveying, and owner preference.
Dodge Torque-Arm (SCXT) is a helical gear reducer for screw conveyor applications. This unit mounts directly to the trough end of the screw, using the optional adapter and drive shaft. It offers a number of accessories available for the toughest application.
The screw conveyor seals can be air-purged by drilling and tapping the adapter housing for standard pipe thread. CinchSeal, instead of grabbing the rotating shaft like mechanical packing or lip seals, as is the customary sealing method, transfers the seal interface from the shaft to a much larger surface of polished stainless steel plated and ...
Our revolutionary Guardian™ Grease Purged Seal is a major step forward. Unlike most others, our Guardian™ seals are constructed of elastomers that center on the shaft – and flex with it.
9.15.1 Screw Conveyors. Screw conveyors are used to convey bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting.
The 316L stainless steel screw feeder shaft on a 3200mm long, 260mm diameter, 1:1 pitch flight screw broke in the middle. The shaft was 50mm Schedule 40 316L stainless steel pipe. The screw flight was 6mm thick 316L plate stitch welded to the shaft. The screw had been replaced new only 4 weeks prior.

· These screw conveyor shaft seals are common for horizontal screw conveyor applications where the shaft seal is not flooded. Plate Seal ($,#) – A plate seal is an oil seal pressed into a steal housing. The seal is sandwiched between the trough end and the flange bearing or screw conveyor drive.
The increasing demand for electrical energy to sustain global development requires consistent heavy investments in power supply generation. However, in addition to complex medium and long-term planning, these investments rely on natural resources, which are becoming depleted due to constant pressures upon the environment.
