Modeling energy requirements in planetary ball milling of ...

Abstract Modified rice flours were obtained by high-impact milling. A factorial design was performed in a planetary ball mill varying rotational speed (450–650 rpm) and milling time (10–40 min) while milling energy (0.3–4.3 kJ/g), particle size distribution (PSD) of rice flour, and changes in starch structure were recorded. The effect of rotational speed and time on milling energy was ...
