flow chart crushing aggregate

Here’s a simplified flow chart for crushing aggregate, outlining the key stages in the process:

Aggregate Crushing Flow Chart

1. Feed Material (Raw Input)
– Quarry rock (e.g., limestone, granite)
– Recycled concrete/aggregate

2. Primary Crushing *(Jaw Crusher or Gyratory Crusher)*
– Large rocks → Smaller pieces (~6–12 inches)

3. Screening (1st Stage) *(Vibrating Screen)*
– Oversize → Return to primary crusher
– Correct size → Proceed to secondary crushing

4. Secondary Crushing *(Cone Crusher or Impact Crusher)*
– Further reduces size (~1–3 inches)

5. Screening (2nd Stage) *(Vibrating Screen)*
– Oversize → Return to secondary crusher
– Correct size → Proceed to tertiary crushing (if needed)

6. Tertiary Crushing (Optional) *(Vertical Shaft Impact Crusher / VSI)*
– Produces finer aggregates/sand (for high-spec applications).

7. Final Screening & Sorting *(Multiple Decks Screens)*
– Separates into sizes (e.g., ¾”, ½”, ¼”, sand, fines).

8. Stockpiling *(By Size Fractions)*
– Ready for transport or further processing (e.g., washing).

9. Optional: Washing & Scrubbing *(Log Washer, Sand Screw)*
– Removes dirt/clay for cleaner aggregates.

10. End Product *(Crushed Aggregate Stockpiles)*
– Base material, concrete aggregate, asphalt aggregate, etc.

Key Notes:
– Closed-Circuit vs. Open-Circuit: Recycled oversize material improves efficiency.
– Dust Control: Water sprays or baghouses may be added for dust suppression.
– Automation: Modern plants use
