### Modified Bond Ball Mill Work Index Test What is this

The Mod Bond results must be calibrated against sufficient standard Bond ball mill work indices, typically 10% of the total The Mod Bond test is used for large variability programs because it provides significant savings in terms of costs (less material required and testing time) and turnaround time, without jeopardising the quality of theThe Bond Work Index of a material is defined as the required energy to reduce one ton of that material from a notional infinite size to a P80 size of 100 µm, the Bond grindability test isPrediction of Bond's work index from field measurableIn general, Bond's work index is used to determine the grinding efficiency and also to calculate the power requirement The process is very time consuming and it requires skilled labor and specialized mill A systematic investigation was carried out to predict Bond's work index using simple field measurable properties of rocksPrediction of Bond's work index from field measurable
