U Type Screw Conveyor Machine Manufacturer
A U type screw conveyor, also called a U-trough screw conveyor, moves powders, granules and grains with a rotating helical screw inside an open U-shaped trough with a removable cover. The open trough makes it the easiest screw conveyor to inspect, clean and maintain.
JS Vibro builds U type screw conveyors at its factory in GIDC Waghodia, Vadodara: 150 mm to 400 mm standard screw sizes, horizontal or up to 15°, shafted or shaftless, in MS, SS 304 or SS 316. Prices start from ₹1,00,000 + GST.

How does a U type screw conveyor work?
- 1Inlet. Material is fed into the U-shaped trough through an inlet at one end.
- 2Rotation. A motor and gearbox turn the screw; the flights push the material along the trough.
- 3Conveying. Screw speed sets the flow rate, so the conveyor can feed the next machine at a steady rate.
- 4Discharge. Material leaves through the outlet at the other end, or through slide gates along the trough.
Why choose an open U-trough
Lift the cover and the whole screw is in view, so cleaning, inspection and changeovers are quick. That is why food, pharma and chemical plants that clean often choose a U-trough over a closed tube.
Main parts
U-shaped trough · screw (shaft and flights) · cover plates · inlet and outlet · end bearings and hanger bearings · coupling and flanges · motor and gearbox · support legs.

Shafted or shaftless U type screw conveyor
Shafted screw
Flights welded to a central shaft. For dry, free-flowing material such as grain, cement, sand, flour and chemical powders.
Shaftless screw
A spiral with no centre shaft, so sticky, wet or fibrous material such as sludge and filter cake cannot wrap around it.
MS construction
For general industry: cement, sand, fly ash, fertilizer and minerals.
SS 304 / SS 316 construction
For food, pharma and chemical plants that need hygiene or corrosion resistance.
U type screw conveyor sizes at a glance
Indicative figures for a horizontal U-trough conveyor. Final size, speed and motor are worked out for your material and length.
| Screw diameter | Capacity (TPH) | Motor (HP) | Speed (RPM) |
|---|---|---|---|
| 150 mm | 2 – 5 | 1 – 2 | 50 – 80 |
| 200 mm | 5 – 12 | 2 – 3 | 45 – 75 |
| 250 mm | 12 – 25 | 3 – 5 | 40 – 70 |
| 300 mm | 25 – 50 | 5 – 7.5 | 35 – 65 |
| 400 mm | 50 – 100 | 7.5 – 10 | 30 – 55 |
Heavier or more abrasive materials run less full and slower, so they need a larger screw for the same output.
