constant when compared to the planetary ball mill. However, an industrial scale vibratory mill, due the containment of velocity, leads slower transformation with respect to other types of mills. The mechanochemical alloying is considered as the versatile method for the manufacture of oxide composites in large quantities [7].
The ballmill process, which is the alternative means for preparing battery oxide, involves tumbling lead balls, cylinders, billets or entire ingots in a rotating steel drum through which a stream of air is passed. The heat generated by friction between the lead pieces is sufficient to start oxide formation.

By contrast, ballmill oxide particles are flat and nonuniform in shape, and are smaller in size [7]. Thus, the surface area and acid absorption of ballmill oxide are much higher than those of Baronpot oxide. Therefore, the active material utilization of ballmill oxide is greater than that of Bartonpot oxide. On the other hand, the active ...
For mechanical milling, a shaker, ball, or mill have generally used at various frequencies from 5 to 60 Hz (Stolle et al. 2014). Common grinding and milling apparatus were shown in Fig. 2. The disadvantages of hand grinding are open and sensitive to environmental factors, while mechanical milling presents an enclosed solventfree medium.
