An aggregate production system is an industrial facility that processes raw materials such as rock, gravel, and sand into various sizes of aggregates used in construction, asphalt, concrete, and drainage applications.

Process and Stages of an Aggregate Production System

  1. Raw Material Sourcing and Transportation
    • Large rock blocks are extracted from quarries or riverbeds.
  2. Pre-Screening and Impurity Removal
    • Unwanted materials like clay, soil, and organic matter are removed.
  3. Crushing Process
    • Jaw Crushers (Primary breaking).
    • Cone Crushers (For medium hardness).
    • Impact Crushers (For softer materials).
    • Roll Crushers (For fine aggregates).
  4. Screening Process
    • Classification into different sizes (0-4mm, 4-8mm, 8-16mm, 16-32mm).
  5. Washing and Purification (Optional)
    • Fine particles and dust are removed to enhance quality.
  6. Storage and Transportation
    • Aggregates are stored in silos or open yards and transported by trucks or trains.

Applications of Aggregate Production Systems

  • Construction and Concrete Production
  • Road and Asphalt Construction
  • Railway Ballast
  • Drainage and Infrastructure Projects
