Introduction: Jaw crushers are powerful machines that are widely used in the mining, quarrying, and recycling industries. These machines are designed to crush large rocks and ores into smaller pieces for further processing. A jaw crusher consists of a fixed jaw and a movable jaw, with the latter being driven by an eccentric shaft that moves the …
DetailsA jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it ...

DetailsBig feed opening enables also the primary jaw crusher to be operated with more open closed side setting (CSS). Larger CSS enables significantly longer lifetime of the jaw dies and higher productivity of the plant. Constant feed opening and wear compensation, in turn, minimize the need to adjust the primary crusher's parameters during operation.
