A crushed stone plant, also known as a stone crushing plant or aggregate crushing plant, is an industrial facility where large rocks are crushed and processed into smaller, specific sizes of stone known as aggregate or gravel. These materials are essential for various construction applications, especially in infrastructure and building development.

What Is It Used For?

  • Road base preparation and asphalt pavement layers

  • Production of concrete in construction

  • Railway ballast for stabilizing tracks

  • Drainage systems in civil engineering

  • Backfill material in retaining walls and foundation works

These plants provide high-quality, standardized aggregates for safe and durable construction.

How Does It Work?

  1. Feeding Unit: Raw materials (rocks or boulders) are fed into the plant via a vibrating feeder.

  2. Primary Crusher (Jaw Crusher): Large stones are broken into smaller sizes.

  3. Secondary Crusher (Cone or Impact Crusher): The crushed stones are further processed for finer output.

  4. Screening Unit: Vibrating screens classify the material by size.

  5. Conveyor Belts: Transfer material from one stage to another and to the storage piles.

  6. Dust Collection System: Filters are used to capture airborne dust and protect the environment.

Advanced plants are often automated and monitored via control systems like SCADA.

Where Is It Used?

  • Highway and expressway construction

  • Concrete batching plants

  • Railway infrastructure

  • Hydroelectric dam construction

  • Airports and large-scale industrial sites

  • Urban infrastructure and drainage networks
