The Bond Ball Mill Work Index BBWi test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stage-crushed to 100 passing size of 3.35 mm.

Jul 30, 2020 An improved method using less mass compared to the Bond Ball Mill Work Index test. The JK Bond Ball Mill JKBBM test, is a locked cycle grindability test conducted using a standard laboratory Bond Ball Mill with the same steel ball charge and material feed size 100 passing 3.35 mm as the Bond Ball Mill Work Index test.
The world widely relies on the ball mill work index for the design and analysis of ball mill circuits, even those that treat AGSAG mill or HPGR circuit products, which have a non-standard particle size distribution. One of the keys of the Bond work index success over time has been its reliability and reproducibility. Provided the original
The Bond Ball Mill Grindability Test determines the Bond Ball Mill Work Index used to determine net power requirements when sizing ball mills. The test is a closed-circuit, dry grindability test.

Sep 12, 2019 However, this requires a significant amount of ore samples, a lot of labor and the pilot plants. Fred Bond published an article in 1961, which, described the procedure for testing ores for a Bond Ball Index. This parameter is still one of the most demanded tools in the design, evaluation and optimization of ball grinding plants around the world.
The Bond Index conforming rod charge consists of 6 rods of 1.25 diameter and 21 length. 2 rods of 1.75 diameter and 21 length. The grinding jar for the Bond Index Rod Mill is 12 x 24 in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.
