There is no fundamental restriction to the type of ball mill used for organic synthesis (planetary ball mill, mixer ball mill, vibration ball mill, ...). The scale of reaction determines the size and the type of ball mill. Vessels for laboratory vibration ball mills are normally restricted to a volume of 50 cm3. Milling material:
Since around 2013, experimental methods to monitor in situ mechanochemical reactions in ball mills using synchrotron Xray powder diffraction [165,166], Raman spectroscopy [167,168,169], or both combined [170,171] have been a breakthrough in the mechanochemistry field.

Mechanochemical methods. Mechanochemical reactions rely on a direct absorption of mechanical energy by reagents, usually solids, during milling or grinding processes. In a typical ball milling process, the energy required to initiate chemical reactions is supplied by friction and impact between balls and reactants.
