The chromite ore is fed into the vibrating feeder by dumper, then it is transported to the jaw crusher for primary crush by vibrating feeder. The crushed coarse chromite is conveyed to the fine jaw crusher by the belt conveyor for secondary crush. After crushing, the chromite materials will be sieved by the circular vibrating screen.
