The Energy Saving Mining Ball Mill is a new developed mill by our factory. It adopts the center transmission, the rolling bearing support, side discharging, overflow discharging and grate discharging. It is suitable for the grinding of the metal mines of less than 25mm feeding and 200mesh discharging.

Run-of-mine ore is crushed underground, hoisted to the surface, then re-crushed to –10mm before grinding in a closed rod mill/ball mill/cyclone grinding circuit. Approximately 48% of the gold is recovered by gravity separation, Knelson concentrators being used to recover free gold and a small portion of the sulphide minerals.

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.
