Screw conveyors, often referred to as screw feeders, are essential in modern industrial operations for efficiently transporting semi-solid materials over short distances. These systems utilize a helical screw blade that rotates within a tube, propelling materials such as plastic granules, feed, wood chips, and more. Ideal for slight inclines, screw conveyors are widely used across bulk handling industries including plastics, food processing, and recycling. Rumtoo Machine, a trusted name in industrial machinery, provides high-quality, custom-engineered screw conveyors designed to meet specific operational needs.
Different Styles of Screw Conveyor
Screw conveyors come in various configurations to suit different applications. The basic mechanism involves a rotating screw within a tube, moving materials at a controlled speed. This makes them a cost-effective solution for transporting semi-solid materials over relatively short distances. Common styles include horizontal, inclined, and vertical screw conveyors, each designed for specific material types and flow requirements.

Screw Conveyor Parts
Hopper
Made of stainless steel, square or rectangular, designed for loading materials. The hopper is inclined to match the screw’s rotation.
Conveyor Tube
Houses the internal screw, made from high-quality stainless steel for durability. Tube diameter can be customized.
Motor & Reducer
Provides constant energy for screw rotation, with a reducer offering variable transmission speeds.
Material Outlet
Can be constructed from 201 stainless steel, 304 stainless steel, or A3 steel based on cost and corrosion resistance requirements.
Electrical Control Box
Features ZHENGTAI brand components with clear functions, alarm systems, and motor overload protection.
Wheels
Equipped with snap-lock wheels for easy mobility and stable support during operation.
Discharging Spot
Connects to other equipment like silos, extruders, mixers, granulators, or crushers for seamless material transfer.
How Do Screw Conveyors Work?
The rotating helical screw moves materials through the tube by pushing them along the conveyor’s length. This efficient mechanism is ideal for semi-solid materials over short distances.
Why Choose Screw Conveyor?
- Enclosed Design: Suitable for dusty, corrosive, or hazardous environments.
- Účinnost nákladů: More affordable than belt, pneumatic, or aeromechanical conveyors.
- Versatile: Handles a wide range of materials, including liquids and solids.
- Wide Applicability: usable indoors and outdoors for various bulk materials.
Considerations When Buying a Screw Conveyor
#1 Height
Consider the required height for integration with other equipment, such as silos or multi-floor transfers.
#2 Transmission Efficiency
Factors like engine power, tube diameter, and screw size affect efficiency (e.g., 3, 5, or 10 tons/hour). Rumtoo Machine provides customized solutions based on operational needs.
#3 Additional Features
Options include heating functions, multiple feed openings, or height adjustments to complement other machinery.
#4 Body Materials
Choose from A3 steel, 201 stainless steel, or 304 stainless steel based on material corrosiveness and budget.
#5 Entire Production Line System
Ensure the screw conveyor integrates seamlessly with other system components for optimal performance.
