Iron Grinding Mill Process

The Six Main Steps of Iron Ore Processing Multotec Canada

The primary grinding mill grinds the material before it undergoes spiral gravity separation. Efficient grinding means that there will be minimal recirculation material from a cyclone cluster or screening after milling, which decreases the kWhr per ton ground.

of the grinding process. Larger particles are forced to the periphery, where the highest-intensity grinding occurs, while smaller particles travel up the mill to the next grinding stage, preventing overgrinding. This multi-stage arrangement eliminates the need for external classification and recirculation, providing a very steep particle size distribution after a single pass. Applications

Cast Grinding Steel Balls - 911Metallurgist

This is particularly true for some of the secondary grinding (primary ball mills) of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive. Meulendyke, Moroz, and Smith (1987)
