Temperature progression in a mixer ball mill

During ball milling up to 80 % of the energy that is generated in the mill is dis-sipated as heat [5] This is why measurement and control of the temperature in the ball mills is important for example if heat-sensitive products are formed that would be degraded or side reactions that would be favored at high temperatures [6 7]
