Screw Sand washer

The screw sand washer is designed for high-efficiency sand cleaning in mining and construction applications. Featuring models like XL920 with robust spiral shafts, it effectively separates dirt and impurities from sand while achieving optimal dewatering. The equipment's unique overflow weir design ensures minimal fine sand loss during washing. With its heavy-duty construction and simple maintenance, this washer is particularly suitable for large-scale sand production plants and concrete mixing stations requiring consistently clean aggregates.

The Screw Sand Washer is essential equipment for intensive cleaning of artificial sand and mineral ores in mining and construction industries. Designed for processing 0-10mm materials with high impurity content, it achieves thorough clay removal (efficiency >95%) while maintaining fine sand recovery rates above 85%. The unique spiral design and counter-current washing principle enable continuous operation with low power consumption (5.5-22kW models available). Particularly suitable for aggregate plants and mineral processing facilities requiring precise material classification.

When selecting models, consider material characteristics (XL920-7.5 for high-clay sand, XL1120-7.5 for coarse aggregates) and system integration (including sludge thickening and water recycling). Future developments will focus on wear-resistant flight liners and IoT-based process monitoring to optimize water usage in environmentally sensitive areas.
