Traditional Wet Milling. The coatings industry is no different from others in its search for modern manufacturing techniques. The traditional highspeed dissolver, ball mill, vertical mill and standard horizontal mill have been the primary methods used to mill pigmented materials for more than 50 years, and are still considered to be the industry standards throughout the world today.

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].

What is a ball mill? A ball mill is a size reduction or milling equipment which uses two grinding mechanisms, namely, impact and shear. 1 Unlike other size reduction equipment, such as breakers and jaw crushers, ball mills are capable of producing powders and particulate materials of mean particle sizes within the 750 to 50 micron (µm) range.. Ball mills serve both dry and wet milling ...
