The rotational speed of planetary ball mill is an important parameter affecting performance efficiency, discharging granularity and grinding energy, but its rotational speed is not that the higher the better, but has a reasonable range.
Finding this reasonable range will allow the performance of the planetary ball mill to be fully utilized and material to be processed with less effort.
When the planetary ball mill running at high speed, the faster the rotational speed is, the faster the temperature of the ball mill system rises.
The excessive temperature is unfavorable for most materials. It will cause the decomposition of supersaturated solid solution, amorphous phase or other metastable phase needed in ball milling, but also possibly cause potential safety hazards such as spontaneous combustion or explosion of powder.
