gyratory reduction crushers characteristics

High reduction ratio crushing in conical/gyratory crushers

Crushers will be able to perform high reduction ratio work at coarser settings, with larger throws, and at slower speeds, without unduly excessive forces being generated in the crusher components. Increased inter-particle contact and grinding results in more fines and enhanced liberation of the valuable constituents in the crusher discharge material.
