Three configurations — tubular for full enclosure, U-trough for volume transfer, vertical for compact elevation. All built at our Noida workshop.
Screw Conveyors for Enclosed Material Transfer
A screw conveyor moves material by rotating a helical flight inside a trough or tube. The rotating screw pushes material along from the inlet to the discharge point — without the material ever being exposed to the surrounding environment. That's the key advantage over belt conveyors for many applications: full enclosure, controlled flow, and the ability to handle fine, dusty, or hygroscopic materials that would spill or degrade on an open belt.
We manufacture three types from our Noida facility. The tubular screw conveyor encloses the flight in a circular pipe — best for fly ash, cement raw meal, fine chemicals, and any material where dust containment is critical. The U-trough screw conveyor uses an open-top channel with a cover plate — easier to inspect, clean, and handle larger capacities. The vertical screw conveyor stands upright and lifts free-flowing material straight up, saving the floor space a bucket elevator would otherwise need.
Every system is sized to your material (bulk density, lump size, moisture, abrasion) and your layout. We provide a GA drawing before fabrication starts.
Choose Your Screw Conveyor Type
Each type suits a different material, layout, and operating condition. Pick the one that matches your situation — or ask us and we'll tell you which fits best.
Conveyor
The screw flight runs inside a round steel pipe — there's no gap, no opening, no spillage. Material enters through a flanged inlet and exits through a flanged outlet at the other end. Because the tube seals completely, it handles fly ash, cement raw meal, fine chemicals, flour, and other dusty or hygroscopic materials without any emission to the surrounding area.
The downside compared to a U-trough is that you can't inspect the flight without disassembly, and cleaning is harder. For materials that don't need frequent flushing, this is rarely a problem.
Fly ash transfer, cement raw meal, flour & grain, fine chemicals, lime powder, carbon black, dusty or toxic materials requiring zero emission
Conveyor
The most common screw conveyor type — a semi-circular U-shaped trough, open at the top, with a removable flat cover. The screw rotates inside and pushes material along from the inlet to the discharge end. The open construction makes it easy to inspect the flight, check for blockages, clean between product runs, and replace worn sections without pulling the entire assembly apart.
U-trough conveyors handle the widest range of materials and are the right choice for most horizontal transfer jobs where dust emission isn't a critical constraint.
Grain handling, sugar mills, fertiliser plants, sludge transfer (wastewater), animal feed, sand & aggregate, hot clinker (alloy variant), biomass
Conveyor
A vertically mounted screw inside a tube, driven from the top by a gearmotor. Material feeds in at the bottom and is lifted straight up to the discharge outlet at the top. The screw must run at higher RPM than a horizontal unit — the flight forces material upward against gravity. This means it's best suited to free-flowing, non-sticky materials that won't pack against the tube wall.
The big advantage is footprint. Where a bucket elevator needs a long boot, casing column, and head frame, a vertical screw fits into a 300–700 mm diameter circle and connects directly to horizontal feeder conveyors at the inlet.
Grain elevation, plastic pellets, fine dry chemicals, spices & food powders, coffee beans, pet food, pharmaceuticals — free-flowing material where a compact vertical lift is needed
Three Types Compared
The right type depends on your material, layout, and dust/containment requirements. This table covers the main decision points.
| Factor | Tubular | U-Trough | Vertical |
|---|---|---|---|
| Enclosure | Fully enclosed tube — zero emission | Open trough with cover — not fully sealed | Fully enclosed tube |
| Orientation | Horizontal / inclined up to 45° | Horizontal / inclined up to 20° | 60°–90° (steep to vertical) |
| Capacity | 1–200 T/h | 2–500 T/h (highest capacity) | 5–200 T/h |
| Max Length / Height | Up to 40 m | Up to 50 m | Up to 15 m lift |
| Screw Diameter | 100–500 mm | 150–600 mm | 150–500 mm |
| Material Type | Fine, dusty, hygroscopic, toxic | Most bulk materials; large lumps possible | Free-flowing, non-sticky only |
| Inspection / Cleaning | Difficult — requires disassembly | Easy — remove cover plate | Moderate |
| Footprint | Linear run | Linear run (wider trough) | Vertical column — very compact |
| Intermediate Bearings | Required beyond 4 m | Required beyond 4–5 m | Not used (no intermediate supports) |
| Drive Speed | 20–150 RPM | 20–120 RPM | 100–500 RPM (higher) |
| Max Temperature | 200°C | 250°C (alloy) | 120°C |
| Best For | Cement, fly ash, chemicals, flour | Grain, fertiliser, sludge, clinker, sugar | Grain elevation, plastic pellets, food powders |
What Goes Into the Build
The components that determine how long the system runs before it needs attention — and what happens when it does.
Where Screw Conveyors Work
Any plant handling fine, powdery, sticky, or enclosed bulk material is a potential application. These are the sectors that use our screw conveyors most often.
