2010; Avolio et al. 2012). However, the milling in small ball mills consumes a lot of energy (Agarwal et al. 2012). Conventional milling operations, such as hammer milling, knife milling and disk milling, typically break down the particle size, but do not alter the CI of cellulose. Only highenergy milling is able to reduce the cellulose CI

In the industry, the fineness of grind is generally achieved with a 2step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.
