XY Spiral Sand Washer With Few Wear Parts And Fully Enclosed Oil-Bath Drive Unit

Welcome to the product overview of the XY Spiral Sand Washer, brought to you by Sichuan Xinyida Machinery Co., Ltd. Designed for excellence in sand processing, our spiral sand washer delivers clean sand, high-efficiency mud-sand separation, and minimal loss of medium-fine sand and stone powder — making it an ideal choice for modern construction and infrastructure projects.

Advanced Design for Superior Sand Quality

The XY Screw Sand Washer features a carefully engineered structure that stirs sand and gravel aggregates through an internal screw device, effectively separating mud and impurities from the materials. Its novel sealed design, combined with a customizable overflow weir plate and a fully enclosed oil-bath transmission system, ensures high efficiency, durability, and outstanding washing and dewatering performance. The result is stable, high-quality fine products that meet the demands of high-grade materials.

How It Works

During operation, particles with higher specific gravity settle at the tank bottom and move toward the bent plate side, where the screw blades push the sand and gravel upward. The water tank extends beyond the lower horizontal line, allowing excess moisture to be removed during upward conveyance. Separated water flows into the fine sand recovery unit, while clean sand is discharged from the upper tank bottom. This integrated design combines washing and dewatering in a single, seamless process.

Key Advantages

• Clean Sand Washing & High-Efficiency Mud-Sand Separation
  The XY Spiral Sand Washer excels at removing clay and other contaminants, delivering consistently clean sand. Its efficient separation process ensures that mud is effectively removed while valuable sand particles are retained.
• Low Loss of Medium-Fine Sand and Stone Powder
  Unlike conventional washers that wash away fine particles, our machine minimizes the loss of medium-fine sand and stone powder, preserving the gradation and fineness modulus essential for high-quality concrete and mortar.
• Durable and Low Maintenance
  With few wear parts and a robust construction, the XY Spiral Sand Washer offers a long service life and requires minimal long-term maintenance. This translates to lower operating costs and less downtime for your production line.
• Stable and Efficient Drive Unit
  The fully enclosed oil-bath drive unit — consisting of a motor, gear reducer, and coupling — ensures smooth, reliable rotation of the screw. The 20° inclined arrangement and three-side weir plates form an optimal sedimentation tank, enhancing both washing and grading efficiency.

Wide Range of Applications

The XY Spiral Sand Washer is widely used for washing, grading, and impurity removal in highway construction, hydropower projects, building construction, and other industries. It is equally effective for washing both fine and coarse materials, making it especially suitable for sand and gravel used in construction and road building.
