Machine Overview
Screw Conveyor Overview
This is a heavy duty bulk handling machine from Swastik Technology, engineered to move grain, powders, granules, minerals and food-grade product horizontally or on an incline through a fully enclosed trough or tube, using a rotating helical screw to push material steadily from the inlet to the discharge point. Also known on plant drawings as an Auger Conveyor or Screw Feeder depending on whether it is moving material in bulk or metering it at a controlled rate, the machine is one of the simplest and most reliable ways to transfer bulk solids over short to medium distances without the dust and spillage risk of an open belt. As an established Screw Conveyor Manufacturer, Swastik Technology builds this Industrial Screw Conveyor range in U-trough and fully Tubular Screw Conveyor configurations, in both horizontal and inclined arrangements, so processors can choose the exact geometry their plant layout needs. Flour mills, feed plants, cement and mineral processing units, chemical plants and grain storage facilities rely on this Screw Conveyor System to connect hoppers, mixers, dryers and storage bins along a single, continuous transfer line. Whether a plant needs a compact Screw Conveyor Machine for a single transfer point or a heavier-duty build engineered for abrasive mineral or continuous multi-shift operation, Swastik Technology matches screw pitch, trough design and drive speed to the material and required throughput.
Equipment
What Is a Screw Conveyor?
It is a mechanical conveying system built to move bulk material through an enclosed trough or tube using a rotating helical screw, sometimes called a flight, that pushes material along as it turns. Material is fed in at the inlet, usually through a hopper or directly from an upstream process, and as the screw rotates, each turn of the flight carries a measured volume of material forward through the trough toward the discharge opening. Because the trough is fully enclosed, this machine, commonly called an Auger Conveyor in agricultural settings, keeps dust contained, protects material from contamination and allows multiple inlet and outlet points to be positioned along the same length of screw. Depending on the application, the same working principle is supplied as a simple Horizontal Screw Conveyor for floor-level transfer between process stages, or on an incline that lifts material at the same time as it moves it forward, reducing the need for a separate bucket elevator on shorter lifts. Built specifically for enclosed, low-spillage transfer, this machine remains one of the most space-efficient pieces of Material Handling Conveyor equipment available, and a Food Grade Screw Conveyor variant with polished stainless steel construction is commonly specified wherever hygiene standards apply.
How It Works
How Does a Screw Conveyor Work?
1
Feeding
Bulk material is fed into the trough at the inlet, usually from a hopper or an upstream machine.
2
Screw Rotation
A motor turns the helical screw at a controlled speed inside the enclosed trough or tube.
3
Material Transfer
Each rotation of the screw pushes a measured volume of material steadily forward along the trough.
4
Intermediate Discharge
Where fitted, intermediate gates allow material to be released at set points along the conveyor length.
5
Final Discharge
Material reaches the end of the trough and discharges into the next process stage, hopper or storage bin.

Frequently Asked Questions
FAQs About Screw Conveyor
The two terms are used interchangeably in most industries. Both describe the same enclosed trough or tube conveyor that uses a rotating helical screw to move bulk material from an inlet to a discharge point.
A horizontal unit moves material along a level trough between two points on the same floor, while tilting it to an incline lifts material at an angle as it moves forward, which can reduce the need for a separate elevator on shorter vertical transfers.
Yes. When fitted with a variable speed drive and sized for accurate volumetric output, the same machine functions as a Screw Feeder, metering material into a process at a controlled rate rather than simply transferring it in bulk.
Depending on configuration, it can handle grain, flour, cement, minerals, chemical powders, fertilizer, sugar and similar bulk material, including food-grade product in a hygienic stainless steel build.
Yes. As a Screw Conveyor Manufacturer, Swastik Technology configures screw pitch, diameter, trough length and material of construction to match the customer’s product and plant layout.
Sizing depends on required throughput, material bulk density, particle size and the transfer distance and incline. Share these details with our engineering team and they will recommend a suitably sized unit for your plant.
