A crushing and screening plant is an industrial facility designed to process natural rocks or stones into aggregates (crushed stone, gravel) of various sizes. These plants play a vital role in mining, construction, and infrastructure projects by producing materials essential for concrete, asphalt, road bases, railway ballast, and more.

How Does It Work?

  1. Crushing Process:

    • Primary Crushers (Jaw crusher, impact crusher): Reduce large rocks (100-150 cm) to 10-15 cm.

    • Secondary/Tertiary Crushers (Cone crusher, vertical shaft crusher): Further break down material into smaller sizes (2-5 cm).

    • Cubical Shaping: Ensures angular edges for better concrete bonding.

  2. Screening Process:

    • Vibrating Screens: Sort crushed materials into specific sizes (0-5 mm, 5-12 mm, 12-25 mm, etc.).

    • Washing Systems (Optional): Remove dust, clay, or impurities.

  3. Storage and Transportation:

    • Aggregates are stored in stockpiles and transported to construction sites via trucks.

Applications:

  • Concrete and asphalt production,

  • Road and railway construction,

  • Landfill and backfill material,

  • Landscaping.

Key Equipment:

  • Crushers, screens, conveyor belts, washing plants, generators.
