Screw Conveyor
Ottevanger screw conveyors are designed for accurate dosing, extraction, feeding and horizontal conveying of bulk materials. The fully enclosed tubular or U-shaped trough limits dust and supports hygiene. A robust drive with intermediate shaft support delivers stable, low-maintenance operation. With multiple diameters, pitches and drive options, each conveyor is configured to the required capacity, footprint and process control.
- Enclosed trough for clean, dust-tight conveying
- Precise feeding and dosing control
- Robust design with long service life

FAQ
Dosing, extracting, feeding and conveying of powders and granulates in an enclosed trough.
By combining frequency-controlled drives, suitable screw pitch and optional shut-off valves to prevent afterflow.
Yes—inclined installation up to 15° is available, depending on product properties and selected execution.
Mild steel, stainless (AISI 304) or galvanised builds, with options for ATEX Zone 22, speed sensing and intermediate outlets.
Intermediate bearings limit shaft deflection, overflow detection protects the process, and the enclosed design reduces contamination and wear.
