Get PriceBond Ball Mill Grindability Test. 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%
Get PriceThe Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.

Get PriceIndices with which the crushing resistance or the grindability in a wide meaning is expressed include the Rittinger number, crushing resistance, Hardgrove index and Bond work index. The Bond work index is regarded as one of the crushing resistance; it can therefore be presumed that the Bond work index is
Get Price28.06.2021· Bond Ball Mill Grindability Test. The test determines the Bond Ball Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements*. Various correction factors may have to be applied. W = Wi (10/√P – 10/√F) Where W = Net power consumption in kWh/t. Wi = Bond work index (either Imperial or
