  • THE EFFECT OF BALL MILL OPERATING PARAMETERS ON

    studied include mill rotational speed, ball size, mill I charge and wet versus dry grinding. Breakage rates have been determined experimentally utilizing a SEM—IPS image analyzer. The mineral sample used was acquired from ASARCO's Young Mine which is located in Jefferson City Tennessee. It was a binary ore consisting of sphalerite and dolomite.
