Q1: How to reduce needle-shaped aggregates?
*A:* Optimize crusher cavity profiles and implement multi-stage screening with AST-S series screens.
Q2: Dust control solutions?
*A:* Integrate AST pulse-jet bag filters (capture efficiency ≥99.5%) with water spray systems.
Q3: Lifespan of wear parts?
*A:* Mn18Cr2 jaw plates last 90,000+ tons in granite crushing; VSI rotors achieve 60,000 hours MTBF.
