CI/QI Impact Crushers

Sandvik CI series horizontal shaft impact crushers combine excellent reduction ratios with consistent product shape. The patented hammer locking system reduces maintenance time, while the optimized rotor design maximizes energy efficiency. CI series models handle primary and secondary crushing of medium-hard materials. Anranst supplies blow bars in Mn18Cr2 and Cr26 with documented mechanical properties.
