Rock Crushers for Commercial Gold Mining Operations

Jew crushers are designed to be heavy duty machines used as the primary crushers in many mining operations. Because of this, the crushers are robustly constructed. The outer shell of the crusher is made from strong steel or cast iron while the jaws are fashioned from hardened cast iron with a Ni-hard or manganese steel removable lining.The crusher was born out of a need for a high capacity underground primary crusher that did not require a primary feeder, scalper, and the associated infrastructure therein. Minimizing the need for high cost stationary grids to control topsize underground was a requisite, and the large topsize acceptance was met with the UG design.Compact primary crusher for above and underground applicationsThe term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant.Primary Crushing - 911 Metallurgistاحصل على السعر
