Testwork Bond ball mill work index

Similar to a Comparative Work Index this test is an open circuit dry batch grindability test run in the standard Bond Ball Mill for a set time It can be used at mesh sizes from 65 to 200 mesh (normally 100 mesh) The test requires calibration against the standard Bond Ball Mill Work Index test to estimate the Work Index Get price
