Three types of ballmills were employed to finely mill the prepared samples: a rotary ball mill (RBM), a stirred ball mill (SBM), and a vibratory ball mill (VBM). These mills consist of a grinding chamber filled with different milling media (balls, beads, cylinders.) set in motion by either movement of the chamber or by a rotor.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

For applications such as water treatment, flue gas treatment, and when used as a raw ingredient to some chemical applications, the quicklime must first be slaked. Slaking occurs when quicklime is reacted with water to form Ca(OH) 2, most commonly called hydrated lime in its dry form or lime slurry or milk of lime in its wet form.
