Construction Sand Cleaning Equipment

1.Product Introduction

Construction Sand Washing Equipment, commonly known as a Sand Washer or Stone Washer, is specialized machinery used to remove impurities such as clay, stone powder, and organic matter from natural or manufactured sand. Its primary objective is to produce clean, well-graded sand that meets construction standards (such as ASTM C33), ensuring the strength and durability of building materials like concrete and mortar. Common types include Spiral, Wheel Bucket, Drum, and Vibrating sand washers.

2.Application

• Construction Engineering: Used for cleaning concrete aggregates in key projects like highways, high-speed railways, bridges, tunnels, and dams, where clay content must be below 1% or even 0.1%.

• Commercial Concrete Batching Plants: Provides clean sand and gravel for ready-mix concrete to enhance structural performance.

• Precast Component Factories: Cleans sand for the production of precast beams, slabs, and pipe piles to guarantee component quality.

• Sand and Gravel Production Enterprises: Performs final cleaning and grading of finished sand after the crushing and screening stages.

• Sand Resource Recycling: Enables the reuse of sand in scenarios such as sandblasting media recovery, water treatment filter media regeneration, and agricultural soil improvement.

3.Working Principle

While the specific mechanics vary by type, the core principle is based on a combination of mechanical agitation, hydraulic scouring, and frictional collision:

1. Spiral Sand Washer
Material enters the lower end of the water tank and is continuously tumbled and pushed by low-speed rotating spiral blades. The material is thoroughly cleaned through friction in the water; impurities are discharged with the overflow, and clean sand is unloaded from the discharge port at the upper end.

2. Wheel Bucket Sand Washer
The motor drives the impeller to rotate in the water tank. Buckets on the circumference scoop up the sand, which comes into full contact with the water and is rinsed during the lifting process. Impurities settle or overflow, and the clean sand is discharged after dewatering.

3. Drum Sand Washer
Material enters a rotating cylinder lined with wear-resistant rubber plates that lift and drop the material. High-pressure water is simultaneously injected, causing the material to be washed repeatedly as it rolls. Clean material is discharged after dewatering via a screen, while muddy water flows out from end plates.

4. Vibrating Sand Washer
Material jumps and rolls on a vibrating screen surface while being continuously rinsed by overhead water sprays. Fine impurities pass through the screen holes and are discharged with the muddy water, while clean coarse sand is unloaded from the end of the screen.

4.Advantages

• High Efficiency & Cleanliness: Can reduce the clay content of sand to below 0.1%, significantly enhancing the compressive strength and durability of concrete.
• Low Material Loss: The wheel bucket and drum designs minimize the loss of fine sand and stone powder, maintaining stable grading.
• Reliable Structure: Key components (such as bearings) are isolated from water and materials, resulting in a low failure rate and easy maintenance.
• Energy Saving & Eco-friendly: Integrated water recycling systems allow for the reuse of water resources and reduce discharge.
• Strong Adaptability: Capable of processing sand and gravel with particle sizes ranging from 0–300mm, meeting diverse cleaning needs from fine sand to large pebbles.
