Spiral Sand Washer
Spiral washing and conveying for aggregate and mineral feed. Trough length, spiral duty and water balance are selected for contamination and capacity.
Configured around the actual process duty
The Spiral Sand Washer is selected from confirmed material, feed, capacity, product and site information. Its duty is reviewed together with upstream feeding, downstream transfer, classification, utilities, maintenance access and the agreed operating schedule.
Suitable feed
Sand, aggregate or mineral feed containing removable clay, silt and fine impurities.
Process position
Washing, light scrubbing and dewatering before product transfer.
Engineering focus
Feed rate, contamination, spiral diameter and speed, water balance, trough inclination and product moisture.
Spiral agitation, washing and discharge
Rotating spiral flights agitate and move material through a water-filled trough. Impurities are released while cleaned product advances to the discharge.
Stable performance depends on controlled feed, correct operating settings, suitable wear or process components and effective coordination with the surrounding plant.
- Application reviewed from confirmed material and duty data
- Operating configuration matched to the required process result
- Wear, maintenance and access requirements considered during selection
- Upstream and downstream equipment reviewed as one process
Information required before model confirmation
Catalogue ranges support early planning. Final capacity and equipment selection require confirmed project data.
| Review item | Information to provide | Engineering impact |
|---|---|---|
| Material properties | Material name, hardness or strength, abrasiveness, moisture and contamination. | Equipment suitability, wear selection and power demand. |
| Feed conditions | Maximum size, typical grading, feed rate and feeding method. | Inlet, loading pattern and upstream configuration. |
| Required duty | Target capacity, operating hours and expected availability. | Equipment size, drive duty and complete circuit capacity. |
| Required product | Target result, discharge specification and downstream process. | Operating configuration and downstream arrangement. |
| Site conditions | Country, altitude, power standard, utilities, installation and layout constraints. | Motor, controls, structure, access and delivery documentation. |

Common selection questions
What information is needed to select this equipment?
Share feed grading, clay or silt content, target sand specification, throughput, water availability and site constraints.
Does the published capacity guarantee site performance?
Usable sand output depends on incoming fines, contamination, wash losses and water balance; the nominal feed rate is not finished-product output.
How is water demand assessed?
Provide the feed and target cleanliness plus water source and discharge limits so the wash circuit can be sized.
Can washing and fines recovery be reviewed together?
Yes. The washer, water management and fines recovery should be assessed as a connected process.
Which parts need regular review?
Paddles, liners, bearings and other service items are selected for the confirmed model and abrasive duty.
