A mineral screening and washing system is an industrial setup used to screen raw materials (rocks, ores, sand, gravel) by size and wash them to remove impurities like clay, soil, or dust. These systems enhance material quality and ensure compliance with industrial standards.

How Does It Work?

  1. Feeding:

    • Raw material is fed into the system via excavators or conveyor belts.

  2. Screening:

    • Vibrating Screens: Material passes through screens with varying apertures to separate it into sizes (e.g., 0-5 mm, 5-20 mm, 20-50 mm).

  3. Washing:

    • Rotary Scrubber: Large materials are washed in a rotating drum with water.

    • Log Washer: Sticky clay is scrubbed off using rotating paddles.

    • Hydrocyclone: Fine materials (sand, silt) are separated via centrifugal force.

  4. Dewatering:

    • Dewatering Screens: Excess water is removed from washed material using vibrating screens.

  5. Storage:

    • Cleaned and sized material is stored in stockpiles or silos.

Applications:

  • Aggregate production (concrete, asphalt),

  • Coal and ore preparation,

  • Sand and gravel quarries,

  • Recycling plants (construction waste).

Key Equipment:

  • Vibrating screens, rotary scrubbers, log washers, hydrocyclones, conveyor belts, water recycling systems.
