High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling is a mechanical deformation process that is frequently used for producing nanocrystalline metals or alloys in powder form. This process has been successfully used to produce metals with minimum particle sizes from 4 to 26 nm. This device is equipped with an automatic hood lock. The lock prevents the device from being started when in an unsafe state. The combination of high-frequency impact grinding, intense friction and circular jar movements ensures an unprecedented grinding performance. The grinding jar supports are each mounted on two discs, which rotate in the same direction, thus moving the grinding jars on a circular path without changing their orientation. The interplay of jar geometry and movement mechanics causes strong friction between the grinding balls, the sample material and the jar walls, as well as high acceleration, which allows the grinding balls to hit the sample material with a strong impact at the curvatures of the jars. This results in a significantly better mixing of the particles with a higher final fineness and a narrower particle size distribution.
