Hand grinding (manual grinding) is generally applied by a mortar and pestle (Takacs 2007) and it is the simplest way for the generation of mechanical energy (Cinčić et al. 2012). For mechanical milling, a shaker, ball, or mill have generally used at various frequencies from 5 to 60 Hz (Stolle et al. 2014).
