اقرأ أكثرThe Vertical vibrating mill is a new design of vibrating mills which are used to produce micro-powders, and nano-powders. This paper studies the effect of four different parameters (rotational speed, the milling media size (ball diameter), the input grain size, and the mass of the rotating mass) on both milling time and output grain size.
اقرأ أكثر8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
