A sand screening and washing plant is an industrial facility designed to remove impurities (such as mud, clay, dust, and organic residues) from natural or crushed sand, classify it by grain size, and prepare it for commercial use. These plants are critical in sectors like construction, mining, and aggregate production.

Purpose

  • Removal of Impurities: Washing eliminates unwanted particles.

  • Size Classification: Vibrating screens separate sand into fine, medium, and coarse grades.

  • Quality Enhancement: Processed sand meets standards for concrete, asphalt, or prefabricated materials.

How Does It Work?

  1. Feeding: Raw sand is loaded via a hopper or conveyor.

  2. Pre-Screening: Large debris is removed using vibrating screens.

  3. Washing: Sand is scrubbed with water in log washers or screw classifiers.

  4. Dewatering: Screens or hydrocyclones remove excess water.

  5. Storage/Transport: Clean sand is stored or shipped.
    Water recycling systems reduce waste and environmental impact.

Applications

  • Construction: Concrete production, road base layers, plastering.

  • Mining: Processing sand from quarries or riverbeds.

  • Industrial Manufacturing: Glass, ceramics, and foundry industries.

  • Recycling: Transforming construction waste into reusable sand.
