Screw Conveyor

✔ Screw Conveyor – a universal device for transporting bulk and granular materials. It ensures reliable, uniform, and controlled product feeding between production stages. Used for transportation, silo and bunker unloading, and dosing.

Design and Types

✔ Construction Types:
Closed (tubular housing) – provides sealing and protection from contamination.
Open (trough-shaped housing) – convenient for intermediate unloading.
✔ Main Components:
Housing: Tubular or trough-shaped, made of stainless or carbon steel.
Screw Spiral: The main working element, which can be solid or paddle-type.
Drive System: Electric motor with a gearbox for speed regulation.
Bearings and Seals: Prevent material leakage and protect against dust and moisture.

Operating Principle

✔ Loading: The material enters the inlet from a bunker or another feeding system.
✔ Transporting: The rotation of the screw spiral moves the product along the housing towards the discharge outlet.
✔ Discharge: The material is delivered to a dosing unit, mixer, or another transport system.
✔ Control and Regulation: Level sensors monitor loading, while the automation system regulates the conveyor’s operation.

Advantages

✅ Reliability and Durability – made from high-quality materials, resistant to wear and tear.
✅ Uniform Material Feeding – ensures production process stability.
✅ Hygienic Design – the enclosed construction prevents product contamination.
✅ Versatile Application – adaptable to various production processes.

Technical Specifications

✔ Materials: Stainless or carbon steel, safe for the food industry.
✔ Length and Diameter: Determined according to production requirements.
✔ Drive Power: Depends on the volume and characteristics of the transported material.
✔ Performance: Defined by the screw spiral’s rotation speed and loading capacity.
The screw conveyor is an efficient solution for production mechanization, increasing productivity, and reducing material transport time.
