Zero fine sand loss sand washing machine | Moisture content ≤15% Fine sand recovery ≥95% - CATHAY

Product Overview

CATHAY sand washing and dehydration machine integrates three functions: washing + dehydration + fine sand recovery. A single machine completes the process of three traditional equipment. The washing rate is ≥99%, the moisture content of finished sand is ≤15%, the fine sand recovery rate is ≥95%, the processing capacity is 50-500 tons/hour, the land occupation is reduced by 60%, and the investment cost is reduced by 45%.

Core advantages

✅ Three effects in one

- Spiral powerful sand washing + high-frequency dewatering screen + cyclone recovery system

- Eliminate sedimentation tank, zero sewage discharge meets standards

✅ High quality control of sand materials

- Mud content ≤0.8% (national standard ≤3%)

- Fineness modulus 2.3-3.0 adjustable

✅ Energy saving and durability

Five major application scenarios

✔ Sand and gravel aggregate plant: integrated machine-made sand washing and dehydration

✔ River sand mining: ship-mounted mobile operation (rust-proof version)

✔ Mine tailings: fine particle resource recovery

✔ Construction waste: recycled aggregate washing and purification

✔ High-standard concrete: fine sand production line (including stone powder control)
