This high circulation rate results in a uniform dispersion, narrow particle-size distribution and faster grinding. There are two types of high circulation mills — one uses 3–10-mm media to process material down to sizes of a few microns, the other uses 0.1-2-mm media to achieve sub-micron and nano-size products.
