Enclosed by design
A rigid tubular body keeps the conveying path compact and limits external dust exposure between connected equipment.
Tubular screw conveyor
Cement Screw Conveyor
Move powder with less exposure and a better fit.
A compact, enclosed conveying route engineered around your material, throughput and plant layout — from silo discharge to weighing, mixing or downstream processing.
Ø89–Ø407mm selection diameters
1.3–170t/h catalog reference range
<15m catalog length coverage
Reference boundaries only. Final capacity, power and dimensions depend on material and layout.
Engineered selection
One conveyor.
Built around the actual duty.
A cement screw conveyor is not selected by diameter alone. Material behavior, throughput, inclination and connection geometry work together. We configure those variables before finalizing the proposal.
Why this configuration
Less complexity between the silo and the process.
Configured for the duty
Diameter, length, angle, drive and connection arrangement are matched to the project instead of forced into one fixed layout.
Serviceable components
Selectable hanger bearings, end bearings and drive arrangements support installation access and planned maintenance.
Layout flexibility
A route that meets your equipment where it is.
Length, inclination, inlet and outlet arrangement can be coordinated with silos, weighing hoppers, mixers and downstream equipment.
Inside support
Selectable hanger bearings.
Intermediate support options are selected around conveyor length and service conditions.
End support
Serviceable end assemblies.
End-bearing and connection arrangements are configured for installation and maintenance access.
Applications
Built for dry-powder handling lines.
Concrete batching
Cement and fly-ash transfer from silo to weighing hopper.
Dry-mix mortar
Enclosed transport of cementitious powders and mineral fillers.
Asphalt plants
Controlled conveying of filler and compatible dry mineral powder.
Building materials
Horizontal or inclined powder transfer between process stages.
Selection boundaries
Start with the range. Finish with the project.
Catalog values help narrow the configuration. The quotation and approved drawing define the final duty.

Faster selection
Four inputs make the first reply more useful.
- Material, bulk density, moisture and particle size
- Required throughput and conveying or metering duty
- Centerline length, inclination, inlet and outlet layout
- Power supply, start frequency and process temperature
Questions
Useful answers before selection.
How is the conveyor size selected?
Selection starts with the material properties, required mass flow, centerline length, inclination, inlet and outlet arrangement, start frequency and available power. We confirm the final size and drive in the technical proposal.
Can the inlet, outlet and angle be customized?
Yes. Length, inclination, connection positions and drive arrangement can be engineered around the plant layout, subject to technical confirmation.
Is the catalog capacity a guaranteed output?
No. The published range is a selection reference. Actual capacity and power depend on the conveyed material, filling, inclination and operating conditions and must be confirmed for each project.
What should I send for a quotation?
Send the material, required throughput, centerline length, inclination, connection layout, power supply and operating temperature. A drawing or site sketch is especially useful.
