Classification of aggregates Based on size: classified into 2 categories: • fine aggregates - those aggregates which pass through 4.75 mm sieve or aggregates with size less than 5 mm. • Coarse aggregates - those aggregates Passing through 75 mm sieve and entirely retained on 4.75 mm sieve OR those aggregates with size greater than 5 mm.

The crushability test results demonstrated that the DRC in cone crusher could be quantified by focusing on the variations in the SRR and P10. The SRR and P10 are associated with three important rock properties, Shore hardness (SH), Los Angeles abrasion loss (LAA, %), and Brazilian tensile strength (BTS, MPa).
