Yan et al. 1 showed an increase in size reduction of quartz with increasing ball size from 3 to 6 mm. With 9 mm steel balls, the grind efficiency is similar to the 6 mm ball charge.
Jul 22, 2021 Vertical wet stirring mill equipment is mainly divided into mixing mill tower mill and sand mill. The barrel of the stirring mill is thicker and the spindle angular velocity is lower. The grinding medium can be either a sphere or cylinder with a diameter of 4-12mm, or a microbead with a diameter of 0.2-3.0mm. The angular speed of the main shaft of the sand mill is relatively high, and the grindi
A ball mill is a drum-grinding unit where balls from solid materials steel, iron, hard alloys, ceramics, etc are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.
