stainless steel U trough screw conveyor
U-shaped screw conveyor is a kind of screw conveyor, which is suitable for small-scale operation, stable transmission, and can play a good role in the limited conditions of the transmission site. The sealing performance is good, and it has great advantages for occasions where the dust is large and where there are requirements for the environment, which can prevent the generation of dust in the conveying process. However, the U-shaped screw conveyor is not suitable for long-distance transportation. The manufacturing cost is larger than that of the belt conveyor, and it is easy for the fragile materials to be destructed.
Performance & Technical Features - Benefits
- Standard design in 304 L stainless steel
- Troughs and screws in modular lengths
- Polygonal or cylindrical inlet and outlet spouts according to our standard
- End bearing assemblies with externally adjustable shaft seals (stuffing box, air or gas-purged, others)
- Wide range of intermediate hanger bearings appropriate for the application (also self-lubricating)
- End flanges welded orthogonally on the trough on special jigs
- End plates carrying flanged end bearing assemblies and closing off the trough
- Modular length helicoid screw flighting with square or variable pitch welded on centre pipe with shaft coupling each end
- Screw sections connected by splined or bolted shaft couplings
- Screws accurately balanced
- Bearing assemblies entirely designed by us to offer the right product for each application
- Perfectly smooth troughs for minimum material residue
- Standard drive units with integrated end bearing assembly and adjustable shaft sealing unit (screws run perfectly balanced due to drive unit directly mounted on screw pipe; substitutes coupling or chain transmission with special drive mount)
Screw conveyor classification:
According to screw conveyor drive classification
1. If the length of U-shaped screw conveyor is less than 35m, it is a single-axis driving screw.
2. If the length of U-shaped screw conveyor is greater than 35m, it is a two-axis driving screw.
According to the screw conveyor middle hanger bearing type
1. M1- is a rolling bearing, adopts type 80000 sealed bearing, and the shaft cap has a dust-proof sealing structure. It is commonly used in areas where it is difficult to refuel, no refueling, or oil contaminates the material. The sealing effect is good, and the hanging shaft has a long service life. Temperature of conveying material ≤ 80°C.
2. M2- is a sliding bearing, equipped with a dustproof sealing device, a cast copper tile, an alloy wear-resistant cast iron tile, and a copper-based graphite less oil-lubricated tile. Commonly used in the transmission of material temperature is relatively high (t ≥ 80 °C) or transport water containing larger materials.
According to screw conveyor material classification
1. Ordinary carbon steel U-shaped screw conveyors - Mainly used in industries where cement, coal, stone, etc. wear out, and there are no special requirements for materials.
2, stainless steel U-shaped screw conveyor - mainly applicable to food, chemical, food and other industries that have requirements for the delivery environment, cleanliness, and will not produce pollution on the material, the use of a long time, but the relatively high cost.
