Essa® Bond Test-Work Equipment. 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.The test work will entail industry standard tests such as the Bond Rod Mill Work Index, Bond Ball Mill Work Index, JK/DWi tests and then some specific batch mill tests. The results of the test work will then be used to determine the parameters required for Simulation. The simulation can then be used to size an entire comminution circuit ...


The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...HGI vs Bond Index Test Bond Index HGI Mill Comparison Tube & Ball mill Babcock mill (ring-ball) Target Particle Size Any size below 3.35mm 75µm Particle Size Range <3.35mm (powder) or pellet size 1.18mm-600µm Mass constriction Volume – 700ml Mass – 50g Output kWh/ton HGI Index Suitable materials Any Good quality coals
