A sand washing and screening plant is a facility used to clean and separate natural or crushed sand into different sizes. The sand is washed with water to remove dirt, soil, and other impurities. Then, it is screened to separate it into different size fractions. This clean and classified sand is used in the construction industry for making concrete, asphalt, plaster, and other materials.

2. Detailed Explanation:
A sand washing and screening plant is an industrial facility that processes raw sand to make it usable. The plant removes unwanted materials (clay, soil, organic waste, etc.) from the sand and separates it into different sizes. These processes improve the quality of the sand, making it suitable for construction and other industrial applications.

Working Principle:

  • Feeding: Raw sand is transferred to the plant using a feeder or bucket.

  • Screening: The sand is passed through vibrating screens to separate coarse and fine particles.

  • Washing: After screening, the sand is washed using washers or hydrocyclones. This stage removes dirt and impurities with water.

  • Dewatering: The washed sand is dewatered using dewatering equipment.

  • Storage: 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

  • Construction and infrastructure projects
