Screw spirals are helical components used in screw conveyors to transport bulk materials such as:
-
grain, feed, flour, powdered mixtures
-
cement, construction materials
-
waste, wood, chemicals
They rotate around a shaft, and through their spiral motion, move the material along a tube or channel.
Key Specifications:
| Diameter : |
From 50 mm up to over 700 mm |
| Pitch : |
Distance between coil peaks – affects throughput |
| Thickness : |
Varies depending on load – from 1.5 mm to over 5 mm |
| Material : |
Carbon steel, stainless steel |
| Winding Direction: |
Right-hand (clockwise) and left-hand (counterclockwise) |
| Coil Length: |
Typically 3 meters, custom lengths available upon request |
Special Variants:
-
Flexible transport springs – an alternative to screw spirals, operate without a central shaft, allowing curved paths and equipment lengths up to 25 meters
-
Custom spirals – made to order: various diameters, thicknesses, and materials
