If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

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].

Ball Mills. In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.

Fig. 3 shows a typical TGDTA curve of the silica powder modified by ml of HTMS after ball milling for 24 h. The DTA curve showed two peaks at approximately 130 and 300 °C. The first endothermic peak corresponds to the loss of physically adsorbed and/or hydrogenbonded water from the silica powder [22].The second exothermic peak is ascribed to the thermal decomposition of hexyl groups [11].
