Low-energy Vertical Shaft Impact Crushers Boost High-quality Manufactured Sand Market, Greatly Optimizing Aggregate Particle Shape

Demand for high-standard manufactured sand for infrastructure surges. Vertical shaft impact crushers adopt rock-on-rock crushing principle to produce round sand grains with low flaky content, fully meeting material standards for high-grade concrete and asphalt pavements. Optimized impeller structure cuts energy consumption by 22% vs old impact crushers, and complete model ranges cover hourly output of 80–180 tons when matched with jaw crushers for full sand-making lines. Recently, multiple domestic sand production lines supporting highway and high-speed rail projects adopt this model, with steady rising purchases from overseas infrastructure projects.
