• Essa® Bond Test-Work EquipmentMineral Stats

    Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index and the Bond rod mill work index. These are empirical indices determined by close circuit grindability tests developed by F.C.Bond in the mid 1930 s.
