2018-7-4 Powder processing is a crucial step for solid-state processing, which normally includes in situ chemical reduction method or ball milling method. The ball milling method enjoys greater popularity in the industry as it is much easier to be controlled. Ball milling methods are usually divided into dry ball milling (DBM) and wet ball

2014-6-1 Unlike in the dry mill, where ball impact velocity is the same for all the ball sizes, the impact velocity in a wet mill increases as the ball size increases. It is easy to understand that the liner life is considerably shorter with large balls than with smaller balls, since the impact impulse increases exponentially as ball size increases.

2014-10-22 A ball mill mixer appears to be a suitable device for mixing electrode slurries, although its effectiveness is overshadowed by the long mixing time. It is therefore desirable to seek alternate mixers that can reduce the mixing time and improve the mixing efficiency. The performance of a mixer can be examined either theoreti-
