A sand washing and screening plant is a facility used to clean, classify, and size natural or crushed sand for use in the construction sector and other industrial applications. These plants remove impurities (clay, soil, organic materials, etc.) from the sand and separate it into different size fractions. The cleaned and classified sand is used in concrete production, asphalt manufacturing, plastering, and other construction applications.

Working Principle and Stages:

  1. Feeding: Raw sand is fed into the plant using a feeder or bucket. This stage ensures a consistent flow of sand into the plant.

  2. Screening: The fed sand is passed through vibrating screens to separate it into different sizes. This process separates coarse particles (gravel, stones, etc.) from fine particles.

  3. Washing: After screening, the sand is washed using washing equipment (washers, log washers, hydrocyclones, etc.). This stage removes clay, soil, and other impurities from the sand using water.

  4. Dewatering: The washed sand is dewatered using dewatering equipment (dewatering screens, cyclones, etc.). This process reduces the moisture content of the sand, making it ready for use.

  5. Storage and Shipment: The cleaned and classified sand is transported to storage areas or prepared for direct shipment.

Applications:

  • Concrete and mortar production

  • Asphalt manufacturing

  • Plastering and screeding

  • Precast element production

  • Various construction and infrastructure projects

Sand washing and screening plants are of great importance in the construction sector for producing high-quality materials. These plants ensure the efficient use of natural resources while contributing to the prevention of environmental pollution.
