A gravel crushing and screening plant is a facility where natural stones (gravel, rock, granite, basalt, etc.) are crushed and classified into specific sizes for use in the construction sector. These plants are used for aggregate production and provide materials for construction projects such as concrete, asphalt, and road construction.

What is it Used For?

  1. Aggregate Production: Produces aggregates (sand, gravel, crushed stone) used in the construction industry.

  2. Sizing: Natural stones are crushed to desired sizes to meet different construction needs.

  3. Quality Control: Screening ensures the quality and homogeneity of the material.

  4. Recycling: Waste materials (construction debris, etc.) are processed and made reusable.

How Does it Work?

  1. Feeding: Natural stones or waste materials are loaded into the feeding hopper.

  2. Crushing Process: Material from the feeding hopper is sent to the primary crusher (jaw crusher, impact crusher, etc.). Here, large stones are broken into smaller pieces.

  3. Screening Process: The crushed material is passed through vibrating screens to separate it into different sizes. The desired size is collected, while others are sent back for further crushing.

  4. Storage and Shipment: Sized material is stored in stockpiles and shipped to required locations.

Working Principle:

  • Crushers: Break stones into smaller pieces. Different types of crushers (jaw, cone, impact) are used.

  • Screening Machines: Separate materials by size. Vibrating screens are the most commonly used equipment.

  • Conveyor Belts: Transport materials within the plant.

  • Control Systems: Ensure automatic operation and increase efficiency.
