Trough Screw Conveyor

Neo Conveyors is a trusted U-trough screw conveyor manufacturer in India since 2007, building open-top trough screw conveyors that combine the simplicity of proven mechanical design with the flexibility your plant needs — multiple inlets, multiple outlets, easy inspection, and fast cleaning between batches. The U-shaped trough gives operators direct access to the screw without dismantling the entire system, making it the preferred choice for industries where cleaning frequency, product changeover, and maintenance access matter as much as throughput. As a specialist U-trough screw conveyor manufacturer in India, every system we build is engineered to your material, your capacity in TPH, and your plant layout — manufactured at our Ghaziabad plant and installed by our own engineers, PAN India.

Advantage of the U-Trough Screw Conveyor

Every screw conveyor moves material. What separates the U-trough design is what happens when the material stops moving — for cleaning, inspection, maintenance, or a product changeover.

With a U-trough screw conveyor, removing the trough cover takes minutes. The screw is fully visible and accessible from above. Cleaning is fast. Inspection is visual and immediate. A worn flight, a blocked outlet, or a residual material buildup is spotted and corrected before it becomes a production stoppage.

In industries where batches change frequently — food processing, chemicals, agriculture — or where regulatory inspection is routine — pharmaceuticals, food — this open-access design is not just convenient. It is operationally essential.

For applications where contamination control requires a fully sealed system, see our Tubular Screw Conveyor.

Which Screw Type Is Right for Your Material?

The screw flight design inside the U-trough is the most critical factor in performance. Neo Conveyors engineers select the screw type based on your material properties:

Screw Type	Best For	Key Benefit
Standard Full Flight	Free-flowing powders, granules — cement, grain, salt, fertiliser	Maximum throughput — most efficient for uniform materials
Ribbon Flight	Sticky, cohesive, or fibrous materials — wet cake, damp clay, animal feed	Prevents build-up on centre pipe — cleans itself during operation
Cut Flight	Materials that need mixing or aeration during transport — compost, sludge	Cuts through material for better mixing and gentle aeration
Paddle Flight	Materials requiring blending or conditioning — fertiliser blends, food mixes	Paddles mix material during conveying — conveyor and mixer in one

Not sure which screw type suits your material? Send us your material datasheet and our engineers will recommend the correct configuration.

Materials We Handle

Material	Typical Plant Application
Cement & Lime	Horizontal transport of cement powder, fly ash, and lime between silos and packing
Grain & Agricultural	Moving wheat, rice, maize, and pulses from intake pits to storage bins or processing mills
Food Ingredients	Sugar, salt, spices, food-grade powders — SS trough with hinged covers for fast cleaning
Fertiliser	Urea, DAP, NPK — multiple inlet and outlet positions for blending operations
Chemicals	Soda ash, pigments, industrial powders — MS or SS trough with covered design
Waste & Sludge	Wet cake, municipal sludge, industrial waste — ribbon or cut-flight screw
Animal Feed	Compound feed, premix — ribbon screw to handle sticky fibrous material without blockage

Key Features

•      Open-top access design: Hinged or bolted covers removed in minutes — full visual inspection and cleaning without dismantling

•      Multiple inlet and outlet positions: Designed to match your existing silos, hoppers, and process equipment — no plant re-layout required

•      Up to 30 TPH capacity: Screw diameter and pitch selected to achieve your required throughput — confirmed before manufacture

•      MS or SS trough: Mild steel for general industrial use — stainless steel for food, dairy, and pharma where hygiene standards apply

•      Four screw flight options: Standard, ribbon, cut-flight, or paddle — matched to your material characteristics and process requirement

•      Horizontal or inclined operation: Works on flat or slight incline up to 20° — for plants where layout requires a small elevation change

•      Slide gate outlets: Controlled discharge at multiple points along the trough — divert material to different process lines from one conveyor

•      Manual to fully automatic: PLC-compatible drive and gate control available for integration with your plant automation system

U-Trough vs Tubular Screw Conveyor — Which Suits Your Plant?

Factor	U-Trough Screw Conveyor	Tubular Screw Conveyor
Dust control	Covered — moderate containment	Fully sealed — zero dust emission
Access for cleaning	Excellent — open-top after cover removal	Requires purge or CIP system
Product changeover	Fast — open, clean, close	Slower — sealed system flush required
Orientation	Horizontal or slight incline	Horizontal, inclined, or vertical
Multiple outlets	Easy — slide gates along trough	Possible but complex
Best for	Cement, grain, food, chemicals, agriculture	Pharma, fine chemicals, high-hygiene food

Frequently Asked Questions

What is the advantage of a U-trough design over a tubular screw conveyor?

The U-trough design gives operators direct access to the screw by simply removing the top cover — ideal for fast cleaning, product changeover, inspection, and maintenance. A tubular screw conveyor is fully sealed and better for contamination-sensitive environments, but slower to clean. Choose U-trough when access frequency matters; choose tubular when zero dust emission is the priority.

Can a U-trough screw conveyor have multiple discharge points?

Yes. Slide gate outlets can be positioned at multiple points along the trough length — allowing material to be diverted to different hoppers, bins, or process lines from a single conveyor. This is commonly used in fertiliser blending and grain distribution applications.

What is the maximum capacity?

Up to 30 TPH as standard — extendable through larger screw diameter and higher RPM. Our engineers will calculate the correct screw size and speed to achieve your required TPH before manufacture.

Can it be used for inclined conveying?

Yes — up to approximately 20° incline for a U-trough design. Beyond 20°, a tubular screw conveyor or vertical screw conveyor is more suitable to prevent material rolling back down the flight. Our engineers will advise the correct conveyor type for your incline angle.

Do you offer stainless steel U-trough screw conveyors?

Yes. Food-grade stainless steel trough, screw, and cover with hygienic design — including hinged covers for fast cleaning. Available for food processing, dairy, and pharmaceutical applications.

What is the lead time for manufacturing?

3 to 5 weeks from order confirmation depending on customisation. All timelines committed in writing before order placement.

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.
