Screw Conveyor
Screw conveyors and under-filter dust transfer equipment.
PRODUCT GROUP
Screw Conveyor
Screw conveyors and under-filter dust transfer equipment. Hantech Filter evaluates material properties, target capacity, line geometry, drive, wear, sealing, and maintenance access together within the same conveying system.
Under-filter dust conveying
Rotary valve connection
Cement and mineral dust transfer
Diameter and motor selection based on capacity
Maintenance and service access
Global technical approach
Screw conveyor capacity is determined by diameter, rotational speed, incline, and material behavior
A screw conveyor is defined not just by its tube and spiral, but by its bearing arrangement, sealing, wear resistance, inlet/outlet layout, and drive selection.
Screw Conveyor decision criteria
Product selection is made by evaluating site data, process risk, maintenance access, and operating cost together.
Information to be clarified before quotation
- Material name, density, and moisture content
- Required capacity and conveying distance
- Horizontal/inclined layout and elevation difference
- Number of inlets/outlets and hopper connection
- Existing motor-gearbox and failure history
Diameter & revolution
Determines capacity; higher rotational speed can increase wear and dusting risk.
Slopes
Horizontal/inclined/vertical conveying changes the fill ratio and motor power.
Bearing
Intermediate bearings, end bearings, and packing seals affect dust leakage and maintenance frequency.
Weathering
Spiral/housing thickness is important for cement, lime, and mineral dusts.
Product / application comparison
| Type / solution | App | Advantage | Caution point |
|---|---|---|---|
| Tubular screw conveyor | Under-filter dust transfer | Enclosed conveying, low dust leakage | Intermediate bearings and cleanout covers are planned for |
| U-type screw conveyor | Lines requiring maintenance access | Easy servicing with a covered housing | Dust sealing is more critical compared to tubular types |
| Heavy-duty screw conveyor | Abrasive mineral/clinker dust | Thick spiral and housing | Motor torque and starting load are checked |
| Feeder screw conveyor | Dosing and controlled feeding | Constant Air Volume Control | Material bridging and fill ratio are tested |

Technical selection
What we evaluate together during the quotation process
Material name and bulk density, ton/hour capacity, particle size, moisture, temperature, line length, incline/elevation difference, operating duration, and connected equipment are all evaluated together.
Capacity and operating regime
Nominal/peak tons per hour, daily operating time, and feed continuity are calculated together.
Material and line geometry
Bulk density, particle size, moisture, abrasiveness, line length, and elevation difference determine the equipment type.
Drive, safety, and maintenance
Motor-gearbox, sensors, guards, service covers, and planned maintenance access are defined from the outset.
