• What is a Wheel Sand Washer?

  A wheel sand washer (also known as a bucket wheel sand washer) is a key downstream device in a sand and gravel production line used for washing, dewatering, and grading. It uses a motor-driven reducer to rotate a bucket wheel (impeller) at low speed in a water tank. The friction and rubbing between sand particles, along with the water flow, removes mud, stone powder, and light impurities from the surface of the sand particles.

  Core Capability in One Sentence:

  Washing raw sand containing mud and powder to the standard cleanliness for construction sand, while controlling the moisture content of the finished sand within a range suitable for stockpiling and transportation.

• Application Scenarios of Wheel Sand Washer

  The applications of wheel sand washers are highly focused, yet extremely broad—any production line that requires washing sand and gravel aggregates cannot function without it.

  1. Manufactured Sand Production Line (Core Scenario)

  Typical Process Location: VSI Sand Making Machine/Cone Crusher → Vibrating Screen → Wheel Sand Washer → Finished Sand Stockpile

  Operating Characteristics: After crushing and screening, manufactured sand has a large amount of stone powder (especially in the 75–150µm particle size) adhering to its surface, with a powder content of 10–20%. The wheel sand washer removes the stone powder through washing and friction, reducing the powder content to below 3–5%, meeting the cleanliness requirements of concrete mixing plants for manufactured sand.

  Recommended Configuration:

  • 30–80 t/h Sand Making Line → XSD2610 (Single Wheel)

  • 80–160 t/h Sand Making Line → XSD3016

  • 160–300 t/h Large Sand Making Line → XSD3624 (Double Wheel)

  2. Natural River Sand/Sea Sand Washing

  Scenario Description: Natural river sand contains 3–8% mud, while sea sand contains salt and shell fragments. It needs to be washed to remove mud and salt before it can be used in concrete.

  Advantages of Wheel Sand Washers:

  • Natural river sand has rounded particles and low mud content; wheel sand washers can meet the washing requirements without excessive washing.

  • For sea sand desalination, two wheel sand washers can be connected in series: the first for coarse washing to remove salt and shells, and the second for fine washing and rinsing.

  • Low fine sand loss rate (< 3%), preserving the high-quality gradation of natural sand.
