Introduction. An iron ore mill relies on the grinding and impact of grinding balls to complete iron ore crushing. The operating process of an iron ore mill is as follows: first, the ores are poured into the mill, and both the ores and the grinding balls are lifted by the lifting bar arranged on the wall of the cylinder body to a certain height, after …

Step 1: Wetting. The first step to wet grinding is eliminating air from the surface of the raw feed, so that each individual particle is fully in contact with the liquid slurry. Ensuring complete contact is vital for effective milling. This requires a liquid with lower surface tension than the free surface energy of the solid.
