Tubular Screw Conveyor

Neo Conveyors is a trusted tubular screw conveyor manufacturer in India since 2007, manufacturing fully enclosed tubular screw conveyor systems that move bulk materials without a single grain escaping into the plant environment. When your material is dusty, hazardous, food-grade, or simply too valuable to spill — an open trough conveyor is not good enough. As a specialist tubular screw conveyor manufacturer in India, we engineer every tubular screw system to your material type, conveyor length, orientation, and capacity — manufactured at our Ghaziabad plant, tested before dispatch, and installed by our own engineers, PAN India.

What Makes a Tubular Screw Conveyor Different?

Most plants start with an open U-trough screw conveyor — and it works well for many applications. But when the material is fine, dusty, hazardous, or hygiene-sensitive, an open trough creates problems: dust escapes into the air, material spills at joints, and cleaning between batches becomes difficult and time-consuming.

A tubular screw conveyor solves all of this. The rotating screw sits inside a sealed cylindrical tube — material enters at one end, moves through the enclosed tube, and discharges at the other end. Nothing escapes. No dust in the air. No contamination risk. No spillage on the floor.

Factor	Tubular Screw Conveyor	Open Trough Screw Conveyor
Dust control	Fully sealed — zero escape	Open top — dust rises freely
Spillage risk	None — enclosed tube	Possible at joints and cover gaps
Hygiene	Excellent — sealed system	Moderate — open to environment
Orientation	Horizontal, inclined, vertical	Horizontal and low incline only
Best for	Food, pharma, cement, chemicals	Grain, aggregates, general bulk
Cleaning	Flush or purge without opening	Requires cover removal and manual clean

For open-trough applications, see our U-Trough Screw Conveyor.

Type Of Tubular screw Conveyor system

Neo Conveyors manufactures tubular screw conveyors in four orientations — each engineered for the specific demands of that installation position:

Configuration	Best Application	Typical Industries
Horizontal Tubular	Moving material along a flat path between process points	Cement, chemicals, food, pharma
Inclined Tubular	Moving material upward at an angle — up to 45°	Agriculture, food processing, plastics
Vertical Tubular	Lifting material straight up — space-saving elevation	Cement silos, grain handling, chemical plants
Heavy-Duty Tubular	Abrasive, dense, or high-temperature bulk materials	Mining, cement clinker, industrial minerals

For dedicated vertical screw lifting, also see: Vertical Screw Conveyor.

Food & Beverage	Flour, sugar, salt, spices, coffee, milk powder — SS food-grade tube and screw
Pharmaceutical	API powders, excipients, granules — clean-room compatible, CIP-capable designs
Chemical & Fertiliser	Soda ash, pigments, fertiliser powders — corrosion-resistant tube options available
Agriculture	Grain flour, animal feed, seed — fully enclosed to prevent contamination and pest entry
Plastics & Rubber	Plastic pellets, PVC powder, rubber crumb — anti-static options available
Mining & Minerals	Mineral powders, lime, barite — heavy-duty hardened screw for abrasive applications

Key Features

•      Fully sealed tube: Zero dust emission and zero spillage — meets dust-control and hygiene requirements in even the strictest plant environments

•      Four screw types: Standard flight for free-flowing material, ribbon for sticky material, cut-flight for aeration, paddle for mixing during conveying

•      Horizontal, inclined, or vertical: One system design covers all three orientations — reduce number of equipment types in your plant

•      Leak-proof end seals: Packed gland or mechanical seal at both shaft ends — prevents material escape even under pressure

•      CIP / flush-clean capable: SS food-grade and pharma designs can be cleaned-in-place with water or steam — no disassembly required

•      Custom inlet and outlet positions: Flanged inlet and outlet matched to your existing silos, hoppers, mixers, or process equipment

•      VFD dosing control: Variable speed allows the tubular screw conveyor to act as a precision dosing feeder — not just a conveyor

•      Abrasion-resistant options: Hardened screw flights and wear-lined tubes available for abrasive minerals and clinker applications

Why Choose Neo Conveyors

•      Manufacturer since 2007: Every tubular screw conveyor is designed and fabricated in-house at our Ghaziabad plant — no outsourcing

•      Application-specific screw selection: Screw type, pitch, and tube diameter selected based on your exact material properties — not a generic standard

•      All four orientations: Horizontal, inclined, vertical, and heavy-duty — all built in-house with the same engineering standards

•      Our engineers install it: PAN India installation and commissioning by our own team — precise seal fitting and speed calibration on-site

•      After-sales support: AMC, spare screw flights, seal kits, and technical support available after every installation

Frequently Asked Questions

What is the difference between a tubular screw conveyor and a U-trough screw conveyor?

A U-trough conveyor is open at the top — suitable for general bulk material handling where dust is not a concern. A tubular screw conveyor is fully enclosed inside a cylindrical tube — essential for dusty, hazardous, food-grade, or pharmaceutical materials where zero spillage and contamination prevention are required.

What screw types are available and how do I choose?

Standard flight for free-flowing powders and granules. Ribbon flight for sticky or cohesive materials that build up on a standard screw. Cut-flight for materials that need aeration during conveying. Paddle flight for mixing or conditioning during transport. Our engineers will specify the right screw type after reviewing your material datasheet.

Can the tubular screw conveyor be used for dosing?

Yes. With VFD speed control, the tubular screw conveyor can act as a precision dosing feeder — delivering a controlled, measurable quantity of material per unit time. This is widely used in pharma, food, and chemical batching applications.

Do you offer food-grade and pharmaceutical-grade designs?

Yes. Stainless steel tube, screw, and flanged ends — electropolished finish — with mechanical shaft seals and CIP (clean-in-place) capability. Suitable for food, dairy, pharmaceutical, and nutraceutical applications.

What is the maximum conveyor length?

Up to 30 metres per section for horizontal tubular conveyors. Longer runs are achieved by connecting sections with intermediate support hangers. Vertical tubular conveyors are typically designed up to 15 metres per stage.

What is the price of a tubular screw conveyor in India?

Price depends on tube diameter, conveyor length, orientation, screw type, and material of construction. Contact Neo Conveyors for a detailed no-obligation technical and commercial proposal.

Do you provide installation and commissioning across India?

Yes — PAN India by our own engineers. Full details at www.neoconveyors.com/technical-support or our FAQs page.
