Key Stages Explained:
1. Raw Material Extraction – Rock is sourced from a quarry or mine.
2. Primary Crushing – Large rocks are reduced to smaller pieces (150–250 mm) using a jaw or gyratory crusher.
3. Screening (Coarse Aggregates) – If only coarse aggregates are needed, they are stockpiled directly.
4. Secondary Crushing – Further reduction (20–70 mm) via cone or impact crushers.
5. Screening & Classification – Material is separated by size; oversize is recirculated.
6. Tertiary Crushing (Optional) – For fine aggregates (<20 mm), VSI or roll crushers may be used.
7. Washing (Optional) – Removes dust and impurities (for high-quality aggregates).
8. Stockpiling – Final products are stored for transport or further processing.
Additional Notes:
– Arrows indicate material flow.
– Feedback loops (e.g., recirculating oversize material) improve efficiency.
