Common Iron Ore Crushing and Screening Process
The three-stage closed-circuit process is used as a preparation operation for grinding. Whether it is iron ore mined underground or open-pit, as long as the raw ore contains not high mud content, it can work effectively. Therefore, this process is a crushing process widely used in large and medium-sized iron ore concentrators.
