Our horizontal shaft impact(HSI) crushing plants are outfitted with Sandvik Prisec™ crushers.
Sandvik's Prisec™ crusher range can be configured to operate in application areas such as quarrying and recycling, in either primary or secondary crushing mode. Sandvik’s patented design gives you amazing adaptability, ensuring you keep pace with ever-changing production requirements.

Overall costs are reduced because there are fewer parts and less maintenance required. The curtains are infinitely adjustable with Sandvik’s patented hydraulic adjustment/braking system that utilizes a standard supply hydraulic power pack.
