  • Correction of Bond Ball Mill Work Index Test for Closing

    This is because work index frequently changes as a function of the product size in comminution. If target grind size during a project is changed or if the test is run at the wrong product size then it is necessarily to provide a correction. The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis
