Energy Efficient Screw Sand Washer

Energy Efficient Screw Sand Washer

1.Product Introduction

The Energy Efficient Screw Sand Washer is a high-performance washing solution featuring a spiral design and an efficient AC motor. Optimized for continuous industrial-grade operations, it uses screw blades to agitate, lift, and classify sand and gravel within a water tank. This process effectively separates impurities and dehydrates the material. Known for its low energy consumption, high durability, and eco-friendly features, it is widely used for raw material purification in construction, mining, and aggregate processing.

2.Application

• Construction & Concrete Industry: Cleans manufactured and natural sand by removing clay, dust, and other impurities to enhance the strength and durability of concrete.

• Sand & Quarry Production Lines: Functions as auxiliary equipment in sand-making systems to classify and wash crushed materials, improving the quality of the final product.

• Glass & Foundry Industries: Ensures high-purity silica sand by removing iron-bearing and coloring impurities to meet precision manufacturing standards.

• Environmental Remediation & Resource Recovery: Used for washing and reclaiming sand from contaminated soil or construction waste, supporting sustainable resource utilization.

3.Working Principle

• Material Feeding: The sand-and-gravel mixture is fed into the inclined water tank through the feeding chute.

• Spiral Agitation: An AC motor drives the reducer to rotate the screw shaft. The spiral blades continuously stir the material, causing sand particles to rub against each other and suspend impurities in the water.

• Impurity Separation: Low-density impurities (such as silt and organic matter) are discharged via the overflow weir, while clean sand is slowly lifted by the spiral blades.

• Dewatering & Output: Water drains away as the sand is lifted. Finally, the clean material is discharged from the outlet, achieving integrated washing, dewatering, and classification.

4.Advantages

• Energy Efficient & High Performance: Powered by AC motors, it consumes 20%–30% less energy than traditional DC models, significantly lowering long-term operational costs.

• Low Material Loss & High Recovery: The spiral structure treats sand particles gently; the recovery rate for fine sand (above 0.15mm) can reach over 90%, minimizing resource waste.

• Durable & Reliable: Critical components are crafted from high-manganese steel or feature anti-corrosion coatings. This ensures high wear resistance and corrosion protection in harsh conditions, leading to extended maintenance intervals.

• Continuous Operation: Featuring a fully enclosed design, the unit supports 24/7 non-stop operation, making it ideal for high-load environments such as medium-to-large scale sand plants and quarries.

• Eco-Friendly & Water-Saving: The system can be integrated with water recycling units to reduce fresh water consumption, fully complying with green production standards.
