What Is The Function Of Sand Washer In Sea Sand Desalination?

The core technology of sea sand desalination is to use wheel-type sand washing machines or spiral sand washing machines to physically clean and remove salt, impurities, and chloride ions from the sea sand, making it meet the standards for construction sand. Sand washing machines are indispensable equipment in the sea sand desalination process.

The function of sand washer in sea sand desalination

1. Impurity Removal Treatment

The sea sand is screened to remove large particles such as pebbles, shells, and corals. Then, it enters a wheel-type sand washing machine for sludge removal, which breaks down the protective film on the surface of the sea sand, making it easier for chloride ions to combine with the water flow.

2. Dechlorination Treatment

After initial screening, the sea sand enters a twin-spiral sand washing machine. High-energy supercritical water is used to thoroughly mix the sea sand, and through physical principles, chloride ions are instantly exchanged, thus achieving dechlorination.

3. Dehydration Treatment

After washing, the sea sand is passed through a linear vibrating screen or dewatering screen to remove excess water, and finally transported to the finished product stockpile by a belt conveyor to complete the sea sand desalination process.
