Common Iron Ore Crushing and Screening Process
The basic forms of the three-stage crushing process are: three-stage open circuit and three-stage one closed circuit. The three-stage open circuit process is used to process argillaceous iron ore with high water content and large and medium-sized iron ore concentrators that are prone to produce a large amount of quartz dust ore.
