Sand Washing Machine
Introduction to Sand Washing Machine
The Sand Washing Machine by Henan Liming Heavy Industry Science & Technology Co., Ltd. is a high-performance cleaning system designed to remove impurities and improve sand quality in aggregate production, mining, and construction applications. With intelligent water recycling, adjustable cleaning intensity, and low energy consumption, this machine delivers perfectly graded, ultra-clean sand for concrete production, glass manufacturing, and other industrial uses.
Available in wheel bucket and screw-type configurations, our sand washers handle capacities from 20-300 TPH with 96%+ impurity removal efficiency.
Working Principle
The advanced cleaning process features:
- Water & Material Mixing Drum – Ensures thorough washing of sand particles
- High-Speed Impeller or Screw – Separates dirt, clay & organic matter
- Dewatering Screen – Removes excess water (down to 12-15% moisture)
- Silt & Water Recycling System – Cuts water usage by 40%+
- Adjustable Overflow Weir – Controls product gradation precisely The specially designed water flow channels and wear-resistant liners maximize cleaning while minimizing sand loss (<3%).
Key Applications
