A river sand screening and washing plant is an industrial facility designed to process raw sand extracted from riverbeds or natural deposits. The goal is to remove impurities such as mud, clay, silt, stones, and organic debris, producing clean, high-quality sand suitable for construction and other industrial uses.

These plants are essential in supplying standardized sand that meets building regulations and technical requirements.

What Is It Used For?

Such plants are used to:

  • Clean raw river sand by removing unwanted materials.

  • Classify sand by grain size using vibratory screens or sieves.

  • Wash particles with water to remove fine dust and residues.

  • Improve sand quality to make it suitable for concrete, mortar, or industrial applications.

  • Ensure consistency in sand characteristics for mass production.

 How Does It Work?

The operational process typically follows these steps:

  1. Feeding Unit: Raw sand is delivered by trucks and unloaded into a feeding bunker.

  2. Screening: Vibrating screens separate large stones and coarse materials from fine sand.

  3. Washing Section: Spiral washers, trommels, or bucket wheels use water and agitation to clean the sand thoroughly.

  4. Dewatering: Excess water is removed using dewatering screens or hydrocyclones.

  5. Storage: Clean sand is stockpiled for drying or transported directly for use.

Modern facilities often incorporate water recycling systems to reduce water consumption and environmental impact.

 Application Areas

  • Construction industry: Concrete production, mortar mixes, brick making.

  • Infrastructure projects: Roads, drainage systems, sewerage works.

  • Landscaping: Garden paths, parks, and decorative features.

  • Glass manufacturing: When high-purity silica sand is required.

  • Prefabricated concrete components.
