Screw Conveyor

Screw Conveyor

A ScrewConveyor (also known as an auger conveyor) is a mechanical device that uses a rotating helical screw blade (flighting) to move bulk materials along a tubular or trough enclosure. Widely used in industries such as cement, food processing, agriculture, chemical, and waste management, screw conveyors are an efficient and enclosed means to handle both dry and semi-solid materials. They are available in various configurations—horizontal, inclined, vertical, or shaftless—and are customizable in terms of diameter, pitch, length, material of construction (e.g., carbon steel, stainless steel, or hardened alloys), and drive systems. Screw conveyors offer dust-free operation, precise material handling, and modular design, making them ideal for handling granular or powdered materials.

Top 10 FAQs of Screw Conveyor

What materials can a screw conveyor transport?
It can handle powders, granules, grains, pellets, cement, fly ash, food items, chemicals, and sludge.
How does a screw conveyor work?
A rotating helical screw blade moves material forward within a trough or tube using the principle of axial rotation.
What are the common types of screw conveyors?

Horizontal Screw Conveyor
Inclined Screw Conveyor
Vertical Screw Conveyor
Shaftless Screw Conveyor
Live Bottom Screw Feeder

What materials are screw conveyors made from?
Typically mild steel (MS), stainless steel (SS304/SS316), or abrasion-resistant steel, depending on the application.
What is the maximum length of a screw conveyor?
Generally up to 40 meters, though longer systems require intermediate hanger bearings or modular sections.
Are screw conveyors suitable for food-grade applications?
Yes. Sanitary stainless steel screw conveyors with FDA-approved seals are used in food and pharmaceutical industries.
Can screw conveyors handle abrasive or hot materials?
Yes, using abrasion-resistant steel and high-temperature rated bearings/seals.
How is the screw conveyor powered?
Typically by an electric motor and gearbox, selected based on material load and speed.
Are they easy to maintain?
Yes. Screw conveyors have few moving parts and are relatively easy to clean and service.
How do I choose the right screw conveyor for my needs?
Based on material characteristics, conveying capacity, length, inclination angle, and environmental conditions.

Applications of Screw Conveyors

Cement and concrete batching plants
Food processing (flour, grains, sugar)
Chemical and pharmaceutical plants
Agriculture (grain handling, feed mills)
Wastewater treatment (sludge transport)
Mining and minerals (sand, ores)
Plastic and polymer industries (pellets, resins)
Power plants (fly ash, coal dust)
Fertilizer plants (urea, NPK granules)
Wood and biomass processing

Benefits of Screw Conveyors
