In an eye-opening recent report it was demonstrated that the ammonia synthesis process could be powered mechanochemically in a simple ball mill laboratory experiment under the seemingly very gentle conditions of 45 °C and 1 atmosphere. The mechanochemical ammonia yield reported was found to be significantly higher than the Haber–Bosch.

As a conclusion, the higher the speed of the sets, the higher the products amount produced in desired size range. The high amount of products produced can also be because of the longer duration of the sets in ball milling process. However, the speed has more effects on products produced compared to duration of the sets in this experiment.
