Wet-stirred milling makes use of suspension-based mixture and has been proved to break the particles into nano-size [6, 7]. This method has been employed for the preparation of biomaterials and drugs [8, 9]. Compared to other milling processes like ball milling, wet-stirred media milling has shown greater performance with improved …

Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful application of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning

For fine grinding using stirred milling, a number of studies suggest that the product size distribution (PSD) spread decreases as the product becomes finer. A study carried out using different types of horizontal stirred mills (Karbstein et al., 1996) shows that the width of the particle size distribution, described by the ratio ( x90 − x10 ...
