The effect of ball mill on the morphological and structural features of cellulose has been described by Okajima and co-workers. 20 They treated microcrystalline cellulose derived from cotton linters in a planetary ball mill at 200 rpm for 4–8 hours in dry and wet conditions with three solvents (water, toluene, 1-butanol). They observed that the different media had an effect on cellulose

Planetary ball mill is a most frequently used system for mechanical alloying since only a very small amount of powder is required. Therefore, the system is particularly suitable for research purpose in the laboratory. The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The

Some high-energy planetary ball mills have been developed by Russian scientists, and these have been designated as AGO mills, such as AGO-2U and AGO-2M. The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g
