The results showed that in wet grinding, about 96 by weight with maximum size reduction d90 and d50 were 12 µm and 3.8 µm at 180 min overall grinding time. Particle size enlargement occurred after the time aforementioned. The scanning electron microscope of ultra fine grinding showed that distortion of platy structure occurred after 180 min.
In the wet grinding process of a stirred media mill the bead size, the specific weight of the grinding media, and the mill speed influence the milling efficiency. When using grinding media with a higher specific weight, it is possible to reduce the bead size without losing milling energy by equal bead filling volume.
Typical process times for ultra fine grinding are several hours in conventional ball mills additional time for grinding breaks to avoid over heating of the sample must be added. In contrast toary ball mills, the new MM 500 produces particles in the nanometer range without requiring any cooling breaks the grinding mechanism based on impact rather than friction generates less heat and
