Washing sand machines are equipment used for washing artificial sand (including natural sand). They are widely used in industries such as sand and stone quarries, mines, building materials, transportation, chemical industry, and concrete mixing stations for material washing. They can remove impurities on the surface of sand and stone, while also breaking the moisture layer around the sand particles, which aids in dehydration and serves the purpose of washing sand.

Sand washer, also known as a stone washer, is a machine primarily used for removing impurities (such as dust) from sand products. Due to its frequent use of water washing, it is referred to as sand washing. Since it usually washes manufactured sand (created from crushed stone), it is also called a stone washer. Due to its different appearance and principle, it is also known as a spiral sand washer, drum sand washer, water wheel sand washer (also known as wheel-type sand washer), and vibration sand washer, etc.

Washing sand machines, also known as sand washing machines, come in various types in the market, but most have single functions, with only a few capable of washing rock, dry sand, river sand, and mixed sand. They are widely used in industries such as sand and stone quarries, mines, construction materials, transportation, chemicals, hydropower and water conservancy projects, and concrete mixing stations for material washing.
