الغسالة الملوثة بالرمال الحلزونية

Spiral Sand Washer, also known as screw sand washer, is professional sand washing, dewatering and impurity removal equipment. It adopts spiral pushing structure. Materials are fully turned over and washed in the water tank, mud, dust and clay impurities are separated from sand and gravel. Available in single spiral and double spiral models. Widely used for manufactured sand, river sand, mountain sand, quartz sand, gravel aggregate. It can be combined with vibrating screen, crusher to form complete sand making production line, and also used for ore washing and classification in mineral processing plants.

1. Deep Cleaning & High Purity Sand
Long-distance stirring and washing inside the tank, materials are fully rubbed. Excellent cleaning effect for high-mud sand, cleaner finished sand compared with wheel bucket sand washer, meets high-standard construction aggregate requirements.

2. Low Fine Sand Loss Rate
Reasonable overflow weir design effectively reduces fine sand outflow with muddy water, improves sand yield and reduces resource waste.

3. Heavy Duty & Wear Resistant
Spiral blades adopt thickened steel plate with wear-resistant overlay. Main bearing is separated from slurry to avoid abrasion, greatly extending service life of key components.

4. Large Capacity & Stable Operation
Continuous feeding and discharging, suitable for large-scale sand production lines. Smooth transmission, low vibration, stable long-hour continuous operation.

5. Simple Structure & Easy Maintenance
Compact layout, fewer vulnerable parts. Easy access for blade inspection and replacement, low daily operation & maintenance cost.
