After first crushing, the material will transferred to cone crusher by belt conveyor for secondary crushing; the crushed iron ore stone will then transferred to vibrating screen for classifying. After classifying, the parts whose size below the mesh size will be transferred away as final products, while the other parts will return to cone crusher, thus forming a closed circuit.
