Screw Conveyors
Screw Conveyors
At Harsha Engineers, we manufacture precision-engineered Screw Conveyors designed for efficient handling of bulk materials, powders, and granules. Built with durable Mild Steel (MS), Stainless Steel (SS), or custom alloys, our screw conveyors are known for their reliability, smooth operation, and ability to transport materials horizontally, vertically, or at an incline. With a simple yet effective design, they are highly efficient for controlled and continuous material flow in demanding industrial applications.
Our Screw Conveyors are widely used in pharmaceutical, chemical, food processing, cement, and agricultural industries, where safe and dust-free handling of materials is essential. Available in a variety of sizes, capacities, and configurations such as U-trough, tubular, or shaftless types, they can be customized to suit specific process requirements. With their robust construction, low maintenance, and energy-efficient performance, Harsha Engineers delivers screw conveyor solutions that improve productivity and ensure long-lasting durability.

Capacity: 200 kg/hr to several tons/hr.
Drive System: Electric motor with gearbox, fixed or variable speed.
Design Options: Horizontal screw conveyors, inclined screw conveyors, shaftless screw conveyors, and tubular screw conveyors.
Accessories: Inlet hoppers, discharge spouts, inspection doors, sensors, and control panels.
The Screw Conveyor works on the principle of rotational movement of a helical screw blade inside a tubular or U-shaped trough:
The screw rotates continuously, driven by an electric motor and gearbox.
As the screw turns, materials are pushed forward along the length of the conveyor.
The design allows for horizontal, inclined, or vertical conveying.
The enclosed system minimizes material loss, dust emission, and contamination.
Screw Conveyors are suitable for handling a wide range of bulk materials:
Pharmaceuticals: Powder transfer, granules, and bulk raw materials.
Food Industry: Flour, grains, spices, sugar, and dairy powders.
Chemicals: Powders, crystals, resins, and catalysts.
Agriculture: Seeds, fertilizers, and animal feed.
Waste Management: Handling of sludge, ash, and biomass.
Mining & Minerals: Cement, limestone, coal, sand, and ores.
Enclosed conveying system prevents spillage, dust, and contamination.
Capable of handling free-flowing and semi-solid materials.
Space-efficient with horizontal, inclined, or vertical installation.
Customizable screw pitch and diameter for different materials.
Low maintenance and long service life.
Energy-efficient and safe operation.
Suitable for continuous or batch operations.
Conclusion
Screw Conveyors from Harsha Engineers offer a reliable, efficient, and hygienic solution for transporting powders, granules, and bulk solids across industries. With robust construction, customizable designs, and enclosed operation, our conveyors ensure smooth material handling, improved productivity, and compliance with industry standards.
