Andesite is a high-quality volcanic rock with compact texture, high hardness, strong wear resistance and good anti-skid performance, which is an ideal raw material for high-grade road surface and road base aggregate in modern infrastructure projects.

Andesite has higher hardness and abrasiveness than ordinary limestone, requiring professional hard rock crushing configuration. Ordinary impact crushers are severely worn and cannot produce qualified high-cubicity andesite aggregate.

SMP exclusive andesite crushing solution adopts jaw coarse crushing + multi-cylinder cone fine crushing + VSI shaping three-stage process. It effectively reduces flaky particles and produces high-compactness andesite aggregate that meets high-standard road engineering requirements.

Processed andesite aggregate is widely used in high-speed highways, municipal trunk roads and airport pavement projects, with high market demand and stable high selling price, becoming a high-profit quarry product.
