Temperature progression in a mixer ball mill SpringerLink

Apr 22, 2016 · 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 heatsensitive products are formed that would be degraded, or side reactions that would be favored at high temperatures [6, 7].
