planetary ball mill (Schwanninger et al. 2004; Zhao et al. 2006; Kim et al. 2013). In terms of hydrolysis sugar yield per unit of energy consumption, a vibratory ball mill performs better than a rotary ball mill, but less well than a planetary mill and a converge mill (Fukumura et al. 2010). The two
attritor type, vibratory type, and tumbling type. In the vibratory type of ball mill, grinding of the materials can be performed with vibratory motions with high frequencies and low amplitudes.

The applicability of the vibratory ball mill to fine powder mixing is investigated using two model 1:1000 binary systems of microfine salicylic acid sucrose and milled tolbutamide with lactose. Mill performance is evaluated by measuring the extent of mixing relative to a specified standard and by comparing the rate of mixing to the RevolvoCube ...
In vibratory ball mills the vessels are subjected to a horizontal, vertical or elliptical arc. Due to sudden changes in the direction the balls inside the vessel are colliding with the wall and each other. In this type of mill usually only a few balls (one to four) and rather simple and small milling jars are utilized. ...
