Conveying technology
Screw conveyor
The screw conveyor moves bulk solids in a tube or trough with a rotating screw. The enclosed design supports low-dust conveying; horizontal, inclined or vertical configurations are assessed for the product and route.

Operating principle
A screw of fixed or variable pitch conveys material through a tube or trough. Diameter and pitch set throughput and fill. Besides conveying, the screw can dose or mix. The enclosed run limits dust and weather.
Where this machine is used
Cement, ash, flour, calcite, fertiliser and grain – for silo feeding, dosing and process lines.

Frequently asked sizing questions
When is a screw conveyor suitable for bulk solids?
It is assessed for enclosed short-to-medium conveying runs and for dosing or mixing duties. Flow behaviour, abrasiveness, moisture, temperature and incline determine suitability.
What data is needed to size the conveyor?
Provide material, bulk density, particle size, moisture, temperature, required throughput, conveying length, lift, incline, connection points and daily operating time.
Tube or trough screw—what is the difference?
A tube screw provides a compact enclosed conveying path. Depending on configuration, a trough screw can simplify access, cleaning and maintenance. Selection follows the product, hygiene, dust containment and installation.
