Stirred mill is more advantageous in micronized and nano grinding. On the other hand, ball mill provides high performance in the coarse (>100 µm) grinding process. Stirred mills should be preferred, especially if finer grinding than 140 µm. In other words, energy savings in micronized grinding can be achieved by the use of the stirred mill.

The surface areas of the micronized samples and original pulp given by BET analysis are shown in Fig. surface area was observed to increase substantially from the original value of m 2 /g to 2560 m 2 /g depending on the conditions applied during micronization. These values are comparable with those reported earlier by Pääkkö et al. (2008) for cellulose nanofiber aerogels.

Fig. 3 illustrates that the energy consumption of the ball mill increases drastically below 75 μm product size and below 30 μm, the trend gets steeper. Therefore, the stirred media mills have found applications in regrinding, fine grinding and very fine grinding operations. The energy efficient operations of stirred mills have been proved by various researchers (Keith, 1990, Corrans and ...
