  • High Energy Ball Mills Instead of Planetary Ball Mills

     · In laboratories worldwide Planetary Ball Mills are frequently used for both quality control and R D. They have a reputation to be the best mills to grind semi-hard to brittle samples to very fine particles in the nanometer range < 100 µm always depending on the sample´s properties.

     · On the other hand planetary ball milling with many small (6 mm) balls involves fewer impacts but more consistent friction-based or shearing contact between balls . Therefore we assume that friction better activates solid-gas mechanochemical reactions than normal impacts because the rate of nitridation in a planetary mill is 2–12 times greater than that obtained in a vibratory mill.
