U Type Screw Conveyor
A U Type Screw Conveyor is an industrial bulk material handling machine designed to transport powders, granules, particles, and other dry or semi-dry materials through a U-shaped trough. Also known as a U Trough Screw Conveyor, this conveyor uses a rotating screw flight to move material continuously from one point to another.
The U-shaped trough provides a practical enclosed conveying structure that helps contain dusty materials while allowing convenient access for inspection, cleaning, and maintenance. Depending on the material characteristics and process requirements, the conveyor can be configured with different screw diameters, lengths, speeds, motors, inlet and outlet arrangements, and construction materials.
U Type Screw Conveyors are widely used in cement plants, mining operations, chemical processing, grain handling, fertilizer production, power plants, food processing, waste treatment, and general industrial material handling.
What Is a U Type Screw Conveyor?
A U Type Screw Conveyor consists of a U-shaped trough housing and a rotating helical screw shaft. When the motor and gearbox drive the screw, the screw flights push the material along the bottom of the trough toward the discharge point.
Unlike a fully tubular screw conveyor, the U trough design provides easier access to the internal screw assembly. A removable or hinged cover can also be installed to reduce dust emission and improve workplace cleanliness.
The conveyor can be used for horizontal conveying and, with suitable design considerations, inclined material transportation. Multiple discharge outlets can also be incorporated into one conveyor for controlled material distribution.
Main Components
A complete U Trough Screw Conveyor generally includes:
U-Shaped Conveyor Trough
Helical Screw Flight
Screw Shaft
End Bearings
Intermediate Hangers
Gear Motor
Coupling
Inlet Chute
Discharge Outlet
Trough Cover
Support Frame
Inspection and Maintenance Access
The screw flight and trough can be manufactured from carbon steel, stainless steel, or other materials according to the application. Wear-resistant components can be selected when handling abrasive materials such as sand, minerals, clinker, or ash.
How Does a U Trough Screw Conveyor Work?
The operating principle is straightforward. Bulk material enters through the feed inlet and falls into the U-shaped trough. The electric motor transfers power through a gearbox and coupling to the screw shaft.
As the shaft rotates, the helical screw flight creates a controlled axial conveying action. Material is pushed continuously along the trough until it reaches the designated discharge outlet.
Conveying speed and capacity depend on factors such as screw diameter, rotational speed, conveyor length, pitch, material density, filling ratio, and installation angle.
For applications requiring accurate feeding rather than simple transportation, the U Type Screw Conveyor can also be integrated with weighing systems, storage bins, hoppers, feeders, crushers, mixers, or other process equipment.
U Trough Screw Conveyor for Bulk Material Handling
The U-shaped design is particularly suitable for applications where convenient maintenance and cleaning are important. The trough can be equipped with a removable cover, inspection openings, and access points.
Typical bulk materials include:
Cement
Coal
Fly Ash
Bottom Ash
Limestone
Sand
Gravel
Mineral Powders
Fertilizer
Grain
Biomass
Wood Chips
Chemical Powders
Industrial Waste
Food Ingredients
For dusty materials, the enclosed trough helps reduce material loss and airborne dust compared with open conveying methods.
Industrial Applications
Cement and Building Materials
U Type Screw Conveyors are frequently used for cement, fly ash, limestone powder, gypsum, clinker-related materials, and other bulk solids. They can transfer material between silos, hoppers, mixers, bagging systems, and processing equipment.
Mining and Mineral Processing
In mining and mineral processing facilities, screw conveyors can transport mineral powders, ore-related fines, sand, and other granular materials. Wear-resistant construction can be selected for abrasive applications.
Coal and Power Plants
U Trough Screw Conveyors can be used in coal handling, fly ash transportation, bottom ash systems, and other bulk material processes. Enclosed conveying is useful where dust control is important.
Agriculture and Grain Handling
The equipment can transport grain, seeds, feed ingredients, fertilizer, and other agricultural materials. Stainless steel or food-grade construction may be selected when required by the application.
Chemical Industry
Powders, granules, additives, and other bulk chemical materials can be transported through a controlled enclosed conveying path. Material selection should be based on chemical compatibility.
Waste and Recycling
U Type Screw Conveyors can handle industrial residues, waste materials, sludge-like solids, and recyclable materials when the conveyor is properly designed for the material characteristics.
Key Advantages of U Type Screw Conveyor
1. U-Shaped Trough Design
The U trough provides a practical structure for bulk material transportation and convenient access for maintenance.
2. Enclosed Material Handling
A cover can be installed to help contain dust and prevent contamination or material loss.
3. Continuous Conveying
The rotating screw provides a consistent flow of bulk materials, making the conveyor suitable for continuous industrial production.
4. Compact Installation
The conveyor requires relatively little floor space compared with some other bulk conveying systems.
5. Easy Maintenance
The U-shaped housing provides convenient access to the screw, bearings, and other internal components for inspection and servicing.
6. Flexible Configuration
Screw diameter, length, pitch, motor power, outlet location, trough material, and support structure can be customized.
7. Wide Material Compatibility
The conveyor can be designed for powders, granules, pellets, ash, cement, minerals, agricultural products, and many other bulk solids.
8. Easy Process Integration
The conveyor can be connected with silos, hoppers, crushers, screens, mixers, packing machines, storage systems, and other production equipment.
How to Select the Right U Type Screw Conveyor
Choosing the correct U Type Screw Conveyor requires more than selecting a conveyor length. Important parameters include:
Material: Provide the material name, particle size, bulk density, moisture content, temperature, and abrasiveness.
Capacity: Specify the required conveying capacity, such as tons per hour or cubic meters per hour.
Conveyor Length: The horizontal or inclined conveying distance determines the required shaft configuration and drive power.
Screw Diameter: A larger screw diameter can provide greater conveying capacity when combined with the appropriate rotational speed.
Installation Angle: Horizontal conveying generally provides different capacity characteristics from inclined conveying.
Construction Material: Carbon steel is suitable for many general applications, while stainless steel may be required for corrosion-sensitive, food, or hygienic processes.
Discharge Arrangement: One or multiple discharge outlets can be configured according to the production process.
Maintenance and Operation
Regular inspection helps maintain reliable conveyor performance. Operators should periodically check the gearbox, motor, bearings, screw shaft, hanger bearings, couplings, and fasteners.
The conveyor should not be overloaded beyond its designed capacity. Excessive material loading can increase motor load and accelerate wear.
Lubrication should follow the manufacturer's recommendations. Wear components should be inspected regularly when handling abrasive materials.
Before maintenance, the electrical power should be disconnected and appropriate lockout/tagout procedures should be followed. Guards and covers should remain correctly installed during normal operation.
