Firstly, the raw hematite ores are evenly sent to a jaw crusher through a vibrating feeder for coarse crushing, then are sent to a cone crusher for fine crushing. Next, the ore is screened by a vibrating screen. Those whose particle size meet the requirements would be sent for grinding, while the others would return the cone c…
