Excessive flaky particles are a common quality defect in crushed aggregate. Aggregate with high flakiness rate has low compression resistance and poor compactness, unable to be used in high-grade roads and high-strength concrete projects, greatly reducing product market value.

Unreasonable crushing process and mismatched equipment configuration are the root causes of flaky aggregate. Single-stage impact crushing and worn crushing cavities will produce a large number of irregular flaky particles.

SMP targeted flakiness improvement solution optimizes the staged crushing system. The laminated crushing principle of hydraulic cone crusher reduces flaky particle generation in advance, and the VSI vertical shaft impact crusher performs final rounding shaping to correct irregular particles.

After process optimization, the aggregate flakiness rate is controlled below 3%, fully meeting high-standard engineering requirements. This solution effectively upgrades aggregate product quality and helps quarries enter high-end engineering supply markets.
