Sandwasher

A sandwasher, also known as a sand screw washer, is a water-based equipment used in material processing for separating soil, mud, and other impurities from sand aggregate. It is commonly employed in sand and gravel aggregates, building materials, hydropower and other industries.

Material:

Sandwashers typically utilize steel as the primary construction material, often incorporating wear-resistant alloys in key components like the impeller and screw blades to withstand abrasive conditions. Rubber linings or other protective coatings may be used in areas prone to high wear.

Purpose:

The primary purpose of a sandwasher is to improve the quality of sand by removing clay, dust, and other fine particles. This process enhances the sand’s suitability for applications requiring high purity and consistent grading. It also aims to recover valuable sand lost during the washing process.

Function:

Sandwashers operate on the principle of separating materials based on density and particle size. The process generally involves the following steps:

1. Feeding: Sand is fed into the washing tank.
2. Agitation: An impeller rotates within the tank, creating a slurry with water. This agitation loosens and dislodges impurities from the sand particles.
3. Separation: A screw conveyor simultaneously moves the sand along the tank’s length. Heavier, cleaner sand settles and is conveyed towards the outlet. Lighter impurities are carried away by the water flow.
4. Discharge: Cleaned sand is discharged from one outlet, while water containing impurities exits through another. Multiple stages of washing can be implemented for higher purity levels.

Usage Scenarios:

• Construction Industry: Preparing sand for concrete, asphalt, and other building materials.
• Aggregate Production: Cleaning and classifying sand and gravel for various applications.
• Hydropower Projects: Removing impurities from sand used in dam construction.
• Mining Industry: Processing sand extracted from riverbeds or quarries.
• Glass Manufacturing: Providing high-purity sand for glass production.

Common Types:

• Single Screw Sand Washer: A basic design featuring a single screw conveyor for separation. Suitable for moderate impurity levels.
• Double Screw Sand Washer: Employs two screw conveyors for enhanced separation efficiency, particularly effective for materials with higher clay content.
• Wheel-Type Sand Washer: Utilizes a rotating wheel with buckets to lift and wash sand, offering high washing efficiency and lower water consumption.
• Fine Sand Washer: Specifically designed for washing fine sand particles, often incorporating vacuum systems to recover even the smallest particles.
• Screw Sand Washer with Dehydration Screen: Integrates a dehydration screen to remove excess water from the washed sand, reducing moisture content and facilitating further processing.
