Silica Sand Washing Plant Sand Washing Equipment

Silica Sand Washing Plant

1.Product Introduction

A Silica Sand Washing Plant is an industrial system designed to purify natural or manufactured sand. Using physical washing methods, it removes dust, clay, silt, salt, and organic impurities to produce high-purity, clean sand that meets industrial standards. These plants are primarily categorized into Spiral (Screw) Type and Wheel (Bucket) Type and are widely utilized in mining, construction, and glass manufacturing.

2.Application

• Glass Manufacturing: Provides high-purity quartz sand to ensure the transparency and strength of glass products.

• Foundry Industry: Produces molding sand for metal casting, improving the surface finish of cast parts.

• Construction Engineering: Used in concrete, mortar, and pre-mixed materials to enhance structural durability.

• Hydraulic Fracturing (Fracking): Prepares high-strength proppant sand for oil and gas extraction.

• Sea Sand Desalination: Removes chloride ions, making sea sand suitable for construction in coastal areas.

• Manufactured Sand Production Lines: Works in tandem with sand-making machines to wash and grade manufactured sand.

3.Working Principle

1. Feeding: Raw sand is fed into the washing tank via conveying equipment.

2. Washing:

   • Spiral Type: A motor drives spiral blades to rotate in the water tank. The sand is continuously tumbled and rubbed, while impurities are discharged from the overflow outlet with the water flow.

   • Wheel Type: A motor drives an impeller to rotate slowly via a reducer. The sand is flipped and rubbed against each other by the impeller; impurities are washed away, and clean sand is lifted by the buckets and discharged.

3. Dewatering: The washed wet sand passes through a dewatering screen or spiral device to separate moisture and reduce water content.

4. Recovery: Some systems are equipped with fine sand recovery units to minimize the loss of fine sand (above 0.14mm), increasing resource utilization.

4.Advantages

• High Cleaning Efficiency: Capable of removing over 95% of clay, dust, and salt, significantly enhancing sand purity.

• Water-Saving & Eco-Friendly: Equipped with a closed-loop water recycling system, it can reuse over 80% of the water, reducing wastewater discharge.

• Low Energy Consumption: Utilizes high-efficiency AC motors, saving 15%–30% of energy compared to traditional DC motors.

• High Reliability: Key components are made of wear-resistant steel, polyurethane, or stainless steel, offering corrosion resistance and a long service life.

• Ease of Operation: Features a high degree of automation and easy maintenance; supports both mobile and stationary installations.

• Multifunctional Integration: Certain models integrate washing, grading, and dewatering into a single unit, simplifying the process flow.
