Temperature progression in a mixer ball mill SpringerLink

Apr 22, 2016 Mechanochemistry using ball mills is a promising technique with applications in organic and inorganic chemistry as well as material sciences [1–4].During ball milling, up to 80 % of the energy that is generated in the mill is dissipated as heat [].This is why measurement and control of the temperature in the ball mills is important, for example, if heat-sensitive products are formed that
