  • Evaluation of a laboratory rod mill when grinding ...

    2012-2-1  In this study, coal grinding experiments were conducted using a laboratory rod mill to obtain the parameters used in the PBM. The tests were carried out using a bituminous coal at various grind times to generate the rates of breakage and breakage distribution. A detailed locked-cycle test was also carried out to simulate continuous grinding.
