Comprehensive Support for Screw Conveyor Solutions
We are committed to helping you resolve your material handling challenges. Our technical team is ready to assist in selecting the optimal geometries and configurations for your screw conveyor needs. Whether for standard applications or custom solutions, our portfolio offers screw conveyors suitable for every requirement.
In addition to standard screw conveyors, we provide specialized options such as feeding screw conveyors, cooling screw conveyors, heating screw conveyors, screw heat exchangers, and petroleum coke preheaters, catering to industries ranging from waste management to the aluminum industry.
Specialized Screw Conveyor Solutions:
Feeding Screw Conveyors:
Our feeding screw conveyors are ideal for filling combustion chambers, calcining furnaces, fluidized bed systems, and waste incineration plants. Even in process conditions where end-side bearings cannot be used, these screw conveyors provide the perfect solution. With decades of experience, we design custom geometries and configurations, incorporating cooling or heating features when required to maintain structural integrity. Abrasive bulk materials are no challenge due to our wear-resistant designs. Multi-shaft versions are also available to meet specific mass flow rates and cleaning needs.
Cooling screw conveyors (Temperatures up to 1200°C):
Cooling screw conveyors are designed to chill a wide range of bulk materials and pasty media, including food products. These screw conveyors are particularly suited for applications requiring the separation of the cooling medium from the bulk product, ensuring contamination-free processing. Materials such as coal bottom ash, fly ash, cement, sodium chloride, PVC, pyrolysis waste, cyanide, and various pastes are efficiently handled by our cooling screw conveyors.
Heating screw conveyors (Temperatures up to 450°C):
Heating screw conveyors are designed for the heating, drying, or heat treatment of diverse bulk materials, such as petroleum coke, pasty media, dust, powders, sludges, and more. They efficiently inject heat into products to achieve desired processes like evaporation, melting, or reaction initiation. For sticky bulk products that tend to bridge or form insulating layers, our heating screw conveyors feature a self-cleaning system to ensure consistent performance and clean surfaces.

Frequently Asked Questions
A Screw Conveyor is a bulk material handling system used to transport powders, granules, and other dry materials through a rotating screw flight inside a tube or trough. It is commonly used for conveying, feeding, dosing, and transferring materials in industrial processes.
A Screw Conveyor works by rotating a helical screw inside a housing. The rotating screw moves material continuously along the conveyor length while controlling the material flow rate. Screw conveyors can be designed for horizontal, inclined, or customized conveying applications.
An Industrial Screw Conveyor is designed to convey a wide range of powders, granules, pellets, and bulk materials, including chemicals, food ingredients, minerals, fertilizers, cement, and construction materials. The conveyor can be customized to suit material density, moisture content, abrasiveness, and flowability, ensuring efficient, reliable, and dust-free material handling.
A Tubular Screw Conveyor provides enclosed conveying and is ideal for powders, fine materials, and applications requiring dust control.
A U-Trough Screw Conveyor is typically used for higher-capacity applications and allows easier access for inspection and maintenance.
The best choice depends on material characteristics, capacity, and installation requirements.
Different types of Screw Conveyors are available depending on the application:
• Tubular Screw Conveyor: Fully enclosed design for powders, fine materials, and dust-sensitive applications.
• U-Trough Screw Conveyor: Suitable for higher capacity conveying with easy access for maintenance.
• Screw Feeder: Designed for accurate feeding and dosing into process equipment.
• Cooling Screw Conveyor: Uses a jacketed trough or internal cooling system to reduce product temperature during conveying.
• Heating Screw Conveyor: Uses a heated jacket or electric heating system to maintain temperature, melt, dry, or prevent material solidification.
• High Temperature Electric Screw Conveyor: Designed for demanding applications where materials require controlled heating at elevated temperatures using electric heating elements.
Yes. A Screw Feeder Conveyor can be designed for accurate feeding and dosing of bulk materials into mixers, reactors, packaging machines, and production systems. Variable speed drives allow precise control of material flow.
Selecting the correct Screw Conveyor depends on:
• Material characteristics
• Required conveying capacity
• Conveyor length and installation angle
• Operating temperature
• Abrasiveness and moisture content
• Dust control requirements
• Industry standards such as food-grade or ATEX requirements
A customized screw conveyor design ensures reliable performance and long service life.
