Model Study of Mechanicochemical Degradation in a Planetary Ball Mill

Sustainability, 2023
The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ball-milling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during

Thermo-mechanical rice flour modification by planetary ball milling

LWT - Food Science and Technology, 2014
Abstract Planetary ball milling is presented as an alternative way to improve the native flour properties by physical modification. A grinding protocol was developed by combination of grinding and pause stages. The effect of rotational speed (450–650 rpm) and milling time (10–20 min) on flour properties were determined using RSM method. The effect of
