Leading Sand Washing Equipment Supplier

LZZG excels in fine sand recovery, eco-friendly zero-discharge system, reliable equipment performance, customized solutions and cost-effective pricing. It is perfectly suitable for projects with high mud content, severe fine sand loss and strict environmental regulations.

1. Superior Fine Sand Recovery & Dewatering

• Leading Recovery Efficiency: Fine sand of 0.16–3mm recovery rate ≥95%, and recovery rate of 75μm (200 mesh) fine particles exceeds 90%.
• Stable Finished Sand Quality: Mud content ≤3% and moisture content ≤8% after washing, fully meeting commercial concrete standards without secondary treatment.
• Excellent Dewatering Effect: High-frequency dewatering screen fitted with polyurethane screen mesh keeps finished sand low in moisture, easy to stockpile and free from water dripping during transportation.

2. Zero-Discharge Closed-loop System

• 95% Wastewater Recycling Rate: Sludge thickening tank matched with filter press realizes mud-water separation, recycled clean water for reuse and achieves zero discharge to solve environmental issues thoroughly.
• Dry Solid Waste Discharge: Moisture content of filter-pressed mud cake is below 20%, which can be directly stacked or used for brick making without slurry overflow, saving floor space and transportation cost.
