Correction of Bond Ball Mill Work Index Tests for Closing Sizes
Bond ball mill test procedure were carried out on crushed ( mm / 6 mesh) material at different screen closing sizes (300 µm 212 µm 150 µm 106 µm and 75 µm). The screening process was conducted in four sets of 12inch diameter screens for sufficient amount of time to avoid too much materials fed into the screen at one time.
