A vertical ball mill (VBM) reactor was evaluated for use in biomass conversion processes. The effects of agitation speed (100200 rpm), number of glass spheres (030 units) and temperature (4046 °C) on enzymatic hydrolysis of rice straw and on glucose fermentation by a thermotolerant Kluyveromyces marxianus strain were separately studied. . The results revealed an important role of the ...

One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when intergrinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the harder to grind material in the mill.
