A crushing and screening plant is an industrial facility designed to reduce rocks, ores, concrete, asphalt, or recycled materials into aggregate sizes and classify them by particle size. It can be stationary or mobile, typically consisting of crushers, screens, conveyor belts, and control systems.
Function:

  • Crushes large materials (rocks, concrete) into aggregate sizes (0-5 mm, 5-15 mm, 15-25 mm).

  • Classifies materials into uniform sizes for compliance with construction and mining standards.

  • Converts demolition waste into reusable materials.
    How It Works:

  1. Crushing Stages:

    • Primary Crushing: Jaw crusher or impact crusher reduces material to 100-300 mm.

    • Secondary/Tertiary Crushing: Cone crusher or vertical shaft impactor crushes material to 0-50 mm.

  2. Screening:

    • Vibrating screens separate crushed material into fine, medium, and coarse fractions.

    • Single or multi-deck screens enable precise classification.

  3. Conveying: Conveyor belts transport materials to stockpiles or subsequent processing units.

  4. Automation: PLC systems optimize feed rate and screen settings.
    Applications:

  • Mining (gold, copper, iron ore processing).

  • Aggregate production (concrete, asphalt, road construction).

  • Recycling of construction and demolition waste.

  • Cement and lime plants.

  • Railway and infrastructure projects.
