than the small ball diameters, but the performance for this ball size had decreased for the -2 mm + mm mono-size feed compared to the bigger -4 mm + mm mono-size feed. This therefore shows that should the material feed size continue to decrease, the smaller balls will perform better than the larger balls during milling, as was mentioned
Further research on the effects of milling conditions ( ball-to-cellulose mass ratio, milling time, ball size and alkaline pre-treatment) on the morphology of the prepared nanocellulose derivatives was undertaken by the group of Wang. 22,23 More in detail, they found out that the size of the milling balls has an impact on the formation of fibrous morphologies rather than …
