A Crushing and Screening Plant is an industrial facility used in mining, construction, and aggregate production to reduce large rocks, ores, or recycled materials into specific sizes and classify them.

Components:

  1. Primary Crusher: Breaks down large rocks initially (e.g., jaw crusher).

  2. Secondary/Tertiary Crushers: Cone or impact crushers for finer sizes.

  3. Screening Machines: Vibrating screens sort materials by size.

  4. Conveyor Belts: Transport materials between stages.

  5. Feeders: Ensure consistent material flow into the system.

Working Principle:

  1. Feeding: Raw material (e.g., rock) is fed into the primary crusher via a feeder.

  2. Primary Crushing: The jaw crusher reduces material to 100-300 mm sizes.

  3. Screening: Crushed material passes through a vibrating screen. Desired sizes are separated; oversized chunks go to secondary crushers.

  4. Secondary/Tertiary Crushing: Cone or impact crushers further reduce material to 20-50 mm.

  5. Final Screening and Classification: Final products (e.g., 0-5 mm, 5-12 mm) are stockpiled or prepared for shipment.

Applications:

  • Aggregate production (concrete, asphalt).

  • Mineral ore processing.

  • Recycling (construction waste).

Additional Systems:

  • Dust suppression units.

  • Automation systems (optimize efficiency and energy use).
