Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.
Ball milling is a simple, fast, costeffective green technology with enormous potential. One of the most interesting applications of this technology in the field of cellulose is the preparation and the chemical modification of cellulose nanocrystals and nanofibers.
