The increment of solubility of starch after milling has been observed using other types of mills where the cold water-solubility increases up to 93% using a stirring mill (Huang et al., 2007) or to 74–93% using a rolling-type ball mill (Zhang et al., 2010). Although, these solubilities were obtained after 2 and 100 h of milling, respectively.
Mechanistic modeling and simulation of a wet planetary ball mill
Owing to the double rotation of the grinding chamber of the planetary mill, the technique that is traditionally used to assist in DEM contact model calibration of tumbling mills, which relies on recording the motion of the grinding charge by a fixed externally positioned camera with the mill fitted with a glass or acrylic lid [45, 46], is not suitable.
