Abstract
Crushing flowsheets and equipment are selected to prepare ore for downstream processes. The crushing equipment standard to the minerals industries has been jaw crushers, gyratory crushers and cone crushers. Recent trends in processing have allowed mine operators to target lower grade ores and refractory ores. Low metal prices have required operators to search for lower cost processing opportunities through higher equipment efficiencies and new equipment developments. The realm of crushers in the minerals industry has expanded to include waterflush cone crushers, vertical and horizontal impactors and high pressure grinding rolls. This paper will look at application of the various types of crushers and how they are incorporated into recent crushing circuits.
