As the rotation speed of the highspeed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is [49, 50]. The parameter setting of the ball mill is shown in Table 1.

To study the effect of mill speed and ball filling on heat transfer, the heat transfer tests were conducted in a Φ305 mm × 150 mm ball mill, which was circumferentially fitted with 12 pieces of trapezium lifters. The crosssection of the lifter had a 30° face angle, a short base width of 12 mm, and a height of 10 mm.
