High energy ball milling process for nanomaterial synthesis
Small experimental ball mills can also be completely enclosed in an inert gas glove box. As a consequence, the contamination with Fe-based wear debris can be reduced to less than 1–2 at.% and oxygen and nitrogen contamination to less than 300 ppm.

As such, the milling has to be paused every 30 minutes to allow the sample/jars to cool down. If left to run continuously, the sample can reach temperatures up to 600 o C. Planetary ball mills offer the best performance when it comes to grinding materials but the aforementioned limitations have stopped many researchers from using these ball mills.

Ball Mill - an overview | ScienceDirect Topics
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Ball Mills – fritsch.de
Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding ...
