Crushers are slow speed machines for coarse reductions and can break large lumps of various hard materials as in the primary and secondary reduction of rocks and ores. In a jaw crusher, the feed is admitted between the two jaws, said to form v-open at the top. One jaw is fixed and the other is movable.
