The ball mill used was a XQXM2 planetary ball mill. A consistent ratio of 10:1 for the ball material was upheld during the ball milling process, and a grinding speed of 200 r/min was sustained. The grinding periods were differentiated, with durations set at 2 h, 4 h, 6 h, 8 h, 10 h, and 12 h, respectively.

When the ball mill main bearing works, heat is continuously transferred to the bearing from the hot material and hot gas (drying and grinding) inside the mill, and the contact surface between the bearing journal and the bushing generates heat due to friction. If not eliminated, the accumulated heat will make the bearing temperature rise to destroy the lubrication of the ball mill bearings, the ...
