Fine Dry Grinding of Iron Ore for Pelletizing

Design Considerations for Selecting a Grinding System. Most dry iron ore grinding installations utilizing the standard type rod or ball mill are grinding high-grade natural ores that do not require beneficiation. Most of these ores occur in the weathered state which results in difficulty in the thickening and filtering stages when wet grinding

Mill (grinding) - Wikipedia

Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG
