• Ore Grinding MillsTypes and Classification – Mineral

    · Depending on the way of ore grinding, they are divided into: Aerodynamic or jet mills (don’t require grinding bodies) Mechanical mills with grinding bodies, which in turn are divided into: drum, roller, runner and disc Aerodynamic or jet mills Ore destruction occurs by hitting armor or by knocking out pieces of material moving at high speed (100200 m/s) in the streams of gas jets

    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 mills are primarily used at gold, copper and

    Crushing is normally carried out on "runofmine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding
