Stone aggregate with high flakiness and poor cubicity cannot be used in high-grade roads, bridges and high-rise building projects, with low market price and limited sales scope. Improving aggregate cubicity is the core way to improve quarry product value and market competitiveness.

The particle shape of aggregate is mainly determined by crushing equipment and process flow. Traditional single-stage impact crushing produces many flaky particles. SMP optimized three-stage crushing and shaping process fundamentally improves stone cubicity through staged crushing and precise shaping.

The process adopts C6X jaw crusher for primary coarse crushing to realize uniform material particle size, hydraulic cone crusher for laminated fine crushing to reduce flaky particles, and VSI sand making machine for final rounding shaping. This combination reduces aggregate flakiness rate to below 3%.

A large number of engineering projects prove that SMP optimized shaping process can produce high-cubicity, high-compactness standard aggregate, which is widely recognized in high-end engineering markets and greatly improves the economic benefits of quarry enterprises.
