Industrial Screw Conveyor Systems — What We Make
Neo Conveyors is a leading screw conveyor manufacturer in India, supplying custom-engineered industrial auger conveyor systems since 2007. Our screw conveyors — also called auger conveyors — use a rotating helical screw blade to move bulk materials in a fully enclosed, dust-controlled flow across horizontal, inclined, or vertical paths. We manufacture five distinct variants: U-trough, tubular, vertical, shaftless, and inclined screw conveyors — each optimised for specific materials, throughput capacities, and plant layouts. Every system is designed and fabricated at our Ghaziabad manufacturing facility and installed by our own engineers PAN India.
How a Screw Conveyor (Auger Conveyor) Works
A screw conveyor — also called an auger conveyor or helical screw conveyor — moves bulk materials through a simple, reliable four-component mechanism. Understanding the principle helps you specify the right type for your material and process.
Material Inlet
Bulk material (powder, granule, or pellet) enters the screw conveyor through an inlet hopper or feed chute. Feed rate is controlled by an inlet gate or screw feeder.
Rotating Screw Flight
A helical screw blade (flight) is welded around a central shaft and enclosed in a U-trough or tube. As the shaft rotates, the flights push material forward — like a large rotating bolt through a nut.
Geared Motor Drive
A geared motor connected to one end of the screw shaft drives rotation. VFD speed control allows precise adjustment of material flow rate (TPH). The motor is sized to the material's bulk density and friction characteristics.
Enclosed Dust-Free Discharge
Material exits through an outlet spout at the far end. The fully enclosed trough or tube prevents dust leakage — critical for cement, fly ash, chemical powder, and food-grade materials.
5 Types of Screw Conveyor Systems We Manufacture
Each screw conveyor variant is designed for a specific application, material type, and installation condition. Select the type that matches your requirement or call our engineers for a recommendation.
U-Trough Screw Conveyor
The standard industrial workhorse. Open-top trough with a rotating screw — best for horizontal transport of grain, cement, sugar, fly ash, and chemical granules. Easy to clean and inspect. Fills to 30–45% capacity. Available in MS and SS304/SS316.
Tubular Screw Conveyor
Fully enclosed pipe body — ideal for fine powders, hazardous chemicals, and food-grade materials that must not contact air or environment. Handles fly ash, cement, pharmaceutical powder, and spices without leakage. Can transport at inclinations up to 45°.
Vertical Screw Conveyor
Elevates bulk material straight up — 90° vertical installation. Requires minimal floor space compared to bucket elevators. Used for grain, sugar, fertilizer, and cement elevation between floors or silos. High-speed screw generates centrifugal discharge at the top outlet.
Shaftless Screw Conveyor
No central shaft — the spiral screw operates inside a wear-resistant liner without a bearing through the material. Prevents clogging with sticky, fibrous, or high-moisture materials: sludge, wet biomass, municipal solid waste, cake material from filter presses.
Inclined Screw Conveyor
Standard screw conveyor modified for inclinations from 15° to 45°. At steeper angles, material slippage is controlled through optimised screw pitch and RPM. Used to convey materials between different floor levels within a single enclosed unit — replacing complex transfer points.
Screw Conveyor Technical Specifications
All screw conveyor systems are made-to-order. Standard parameter ranges are listed below as a guide. Capacity, diameter, and motor sizing are calculated per your material bulk density and required TPH.
| Capacity | 1 TPH to 50 TPH (custom calculation per material) |
| Screw / Auger Diameter | 100 mm to 600 mm |
| Conveyor Length | Custom — as per plant layout |
| RPM | Calculated per material type and capacity |
| Inclination | 0° (horizontal) to 90° (vertical) |
| Screw Flight Type | Standard / Ribbon / Paddle / Shaftless |
| Material of Construction | Mild Steel (MS) / SS304 / SS316 |
| Surface Finish | Painted / Powder Coated / Polished (SS) |
| Drive | Geared motor — flange or foot mount |
| Speed Control | Fixed or Variable (VFD) |
| Inlet / Outlet | Custom flange / spout / hopper as per process |
| Sealing | Lip seal / Mechanical seal (food/pharma grade) |
| Power Supply | 415 V, 3 Phase, 50 Hz |

Industries Using Screw Conveyors
Screw conveyors are the preferred bulk material handling solution across eight major industries in India and globally. Each industry has specific material and hygiene requirements that drive the choice of screw type and MOC.
🏗️Cement Industry
Screw conveyors handle cement powder, fly ash, and raw meal transfer between silos, hoppers, and packing lines. Enclosed design prevents dust emission. MS with hard-facing on flights for abrasion resistance.
Cement screw conveyor🍎Food Processing
SS304 and SS316 food-grade screw conveyors for flour, sugar, spices, milk powder, and food ingredients. Polished interior, hygienic seals, and easy-clean design for contamination-free operation.
Food grade screw conveyor🧪Chemical Plants
Enclosed tubular screw conveyors for chemical powders, pigments, and granules. Prevents personnel exposure to hazardous dust. SS316 construction for corrosion-resistant handling of reactive chemicals.
Chemical screw conveyor🌱Fertilizer Industry
Heavy-duty screw conveyors for urea, DAP, potash, and NPK granules. High-capacity horizontal and inclined conveyors from bagging lines to storage. MS construction with anti-corrosion paint.
Fertilizer screw conveyor💊Pharmaceutical Plants
SS316L screw conveyors with FDA-compliant seals for API powder, granules, and excipient handling. Smooth bore for easy validation. Polished finish meets GMP standards.
Pharma screw conveyor🌾Grain & Agro Processing
Horizontal and vertical screw conveyors for wheat, paddy, soybean, maize, and rice husk. High throughput grain elevating and transfer between storage bins and processing equipment.
Grain handling conveyor♻️Fly Ash & Waste Handling

Screw Conveyor vs Belt Conveyor vs Pneumatic Conveying
Industrial material handling engineers frequently compare these three conveying methods. Here is an objective comparison to help you specify the right system for your plant.
| Factor | ✅ Screw Conveyor | Belt Conveyor | Pneumatic Conveying |
|---|---|---|---|
| Powders & fine dust | Excellent — fully enclosed | Poor — open belt causes dust | Excellent — enclosed pipe |
| Sticky / fibrous material | Good (shaftless type) | Limited — material sticks | Not suitable |
| High throughput (>50 TPH) | Limited — use multiple units | Excellent | Good |
| Long distance (>50 m) | Less efficient — use belt | Excellent | Excellent (lean phase) |
| Vertical lifting | Good (vertical screw type) | Requires inclined belt + steep angle | Excellent |
| Food / pharma hygiene | Excellent — SS polished interior | Belt is difficult to sanitise | Good — closed system |
| Installation cost | Low to moderate | Low | High — compressor, piping, filters |
| Energy consumption | Low | Low to moderate | High — compressor power |
| Maintenance | Low — few moving parts | Medium — belt replacement | High — filter, blower, nozzles |
