A screw conveyor machine is a mechanical bulk material handling equipment that uses a rotating helical screw blade — called a “flight” — wound around a central shaft, enclosed within a tube, pipe, or U-trough. As the shaft rotates, material is pushed forward along the conveyor from one end to the other.
Screw conveyors are one of the oldest and most reliable methods of moving bulk solids, offering precise flow rate control simply by adjusting the rotational speed of the shaft. They are fully enclosed, minimizing dust, spillage, and contamination making them ideal for hygienic and hazardous environments alike.
JS Vibro manufactures screw conveyor machines in diameters from 100 mm to 600 mm, lengths up to 15 meters, and capacities ranging from 0.5 TPH to 50 TPH, driven by helical geared motors or chain drive mechanisms.

Heavy-Duty Construction: Built with robust MS or SS troughs, sectional or continuous flights, and leak-proof covers designed for long-term industrial use.
Precise Flow Control: Material transfer rate is directly regulated by shaft rotational speed, providing accurate control over output for powders and bulk solids.
Dust-Free Operation: Fully enclosed design prevents material spillage and dust emissions, ensuring a clean and safe working environment.
GMP Compliant Design: Pharma-grade screw conveyors are manufactured in compliance with GMP standards — smooth internal finish, no dead zones, easy-to-clean design.
ATEX Flameproof Option: Available with ATEX Zone 21/22 certified flameproof configurations for use in hazardous and explosive dust environments.
Versatile Material Options: Available in SS 304, SS 316, SS 316L for corrosive or hygienic applications, and mild steel with painted or coated finish for general industrial use.
Easy Maintenance: Modular construction and quick-access panels reduce downtime. Spare parts are readily available for all models.
Custom Engineering: Every conveyor is engineered to order — custom lengths, diameters, inclination angles, inlet/outlet positions, and drive configurations.
Gentle on Products: Controlled screw flight design ensures minimal product breakage, making it suitable for fragile materials like food pellets or pharmaceutical tablets.
Energy Efficient: Low-power helical geared motor drives deliver consistent performance with reduced energy consumption.
