Hammer mills are more energy-efcient in producing fne particles than knife mills (Liu et al., 2016a; Miao et al., 2011) and are appropriate for producing fne particles (Liu et al., 2016a). Also, the relationship be-tween particle size change and energy consumption was described by a number of comminution laws (Charles, 1957).
