A Spiral Sand Washer—also known as a screw sand washing machine—is a heavy-duty mineral processing equipment used to clean, classify, and dewater sand and gravel. Designed with a long helical blade rotating inside a water-filled tank, it separates impurities from sand through friction, sedimentation, and mechanical agitation.
Its central focus is to present a professional overview of performance parameters, product advantages, operational logic, and long-term development trends—ensuring the content aligns with high-value search intent and reader expectations in global markets.
A well-engineered Spiral Sand Washer integrates mechanical reliability with optimized washing efficiency. The following table outlines typical technical parameters widely referenced in industrial applications:
| Parameter | Typical Range / Description |
|---|---|
| القطر الحلزوني | 500–1500 mm |
| الطول الحلزوني | 5000-12000 ملم |
| Capacity | 20-350 طن/ساعة حسب الموديل |
| Motor Power | 7.5–30 kW |
| سرعة الدوران | 21–35 r/min |
| Water Consumption | Adjustable based on material quality |
| Tank Design | Welded heavy-duty steel tank |
| طريقة التفريغ | Overflow for fines, bottom discharge for cleaned sand |
| مواد التطبيق | رمل النهر والرمل المصنوع آليًا والحصى والغرامات الخام |
| الوظائف الأساسية | التنظيف، الدرجات، إزالة الشوائب، نزح المياه |
These parameters influence washing quality, energy consumption, loss rate of fine sand, and the machine’s ability to operate in harsh environments such as mining, aggregate plants, and large construction production lines.
Several structural and mechanical benefits contribute to the rising popularity of Spiral Sand Washers:
The machine operates at a relatively low speed, minimizing wear on the spiral blade and tank. This controlled motion lowers maintenance frequency compared with high-speed water washing systems.
Because sedimentation is gravity-driven, the Spiral Sand Washer provides a consistent method for separating undesired silt, clay, and organic matter from finished sand.
The spiral design ensures sand particles remain within the tank while impurities overflow. Advanced versions integrate deep-water tanks to reduce fine sand wastage.
Whether dealing with coarse aggregates or fine machine-made sand, the adjustable water flow and rotational speed allow precision control.
The enclosed water circuits enable recycling, reducing site-level environmental impact and water consumption.

The slower rotational speed and thickened materials lead to decreased mechanical stress and extended operating cycles.
Spiral systems handle clay-rich feed more effectively due to deeper agitation and sedimentation effects.
The gravity-assisted classification naturally reduces power requirements.
Fine particles remain inside the tank, preventing economic loss and improving the final grading index.
Future systems will incorporate sensors to monitor water turbidity, blade load, and motor status to improve efficiency.
Combined washing and recovery units will become common in machine-made sand production lines.
Closed-loop water recycling and reduced-waste solutions will shape the next generation of washing systems.
As global infrastructure expands, consistent supply of high-quality sand will remain essential, driving continuous innovation.
A: Capacity selection depends on raw material type, desired cleanliness, and downstream processing requirements. For a medium-scale sand plant, models producing 80–150 tons/hour are common. High-capacity sites typically choose dual-spiral configurations reaching up to 300 tons/hour. Evaluating mud content and feed size distribution ensures proper model selection.
A: Water flow rate, spiral rotational speed, sedimentation distance, and raw material cleanliness all influence the final quality. If the feed contains excessive clay, pre-screening or soaking may be required to achieve optimal washing performance. Regular tank cleaning also maintains classification stability.
The Spiral Sand Washer plays a crucial role in delivering clean, stable, and high-quality sand for construction, mining, and industrial processing. From durable structure and controlled washing processes to adaptability and environmental benefits, it supports both present-day demand and future technological advancements.
