Best way to determine the ball-to-powder ratio in ball-milling?

To really choose, I guess it depends on the material and your mill (vial, RPM, media, filling volume). I.e. Si80Ge20 is easily alloyed in the high energy SPEX mill. But thermoelectric materials like skutterudites with a peritectic decomposition don't do so well in the SPEX. They can be contaminated by the harden steel vial, and...

Scale-up methodology for tumbling ball mill based on impact energy ...

In ball-milling treatments of powders, most of the impact energy may contribute to the powder grinding although a part of the impact energy dissipates due to ball–powder bed interactions such as compression and friction except when the amount of powder placed in the mill is too much. Thus, there is no doubt that the...

Ball Mill Heat Balance Explanation - The Cement Grinding Office

Cement mill heat balance. 1, Introduction: -, It is well known that the biggest part of the energy introduced in a ball mill is converted into heat. -, Only around 5% of this energy is used to grind the material at the required fineness. -, As a consequence, this heat can induce very high temperatures inside the cement mill.
