A ball mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. the rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill.
A resin component is usually incorporated into the carrier liquid to maintain dispersion of the pigment thereby stabilizing its charge state. in the preparation of liquid developers, an intimate mixture or paste of pigment, resin and a small amount of a carrier liquid is first prepared by the aid of a kneader or mixer such as ball mill.
A small number of ball mills are also in use, though these are uneconomic by comparison with agitator mills and dissolvers. 3) stabilization of pigment dispersions: the uniform distribution of the pigments brought about by the dispersion process is only a feasible technical solution if the distribution state is also retained during formulation.

Bruce muller, in applied plastics engineering handbook, 2011. 24b.2 pigments. pigments are classified as inorganic and organic. both pigment classes are insoluble in resins and therefore require high shear to become properly dispersed in a resin. quality dispersion of pigments requires wetting the pigment surface, dispersing (breaking up the agglomerates with shear).
Carbon black is a black pigment that has been used in a wide range of fields such as newspaper ink, printing ink, colored resin, paint, toner, colored paper, india ink, and ceramics. various grades of carbon blacks are available ranging from all purpose grade to highgrade.

Vibration mills are a common class of equipment used for fine and ultrafine grinding and conducting mechanochemical processes 58,59. the fundamental difference between vibration mills and the ball ones is that instead of circular motion, the reactor makes vertical vibrations (figure 5). therefore, within the reference frame of the reactor.
Paint and coating manufacture. adapted from niosh 1984. paints and coatings include paints, varnishes, lacquers, stains, printing inks and more. traditional paints consist of a dispersion of pigment particles in a vehicle consisting of a filmformer or binder (usually an oil or resin) and a thinner (usually a volatile solvent).
Pigments are added slowly, from containers of 10 kg up to 1000 kg, to a portion of the liquid paint components, with the mixer running, to form the millbase. certain pigments are more difficult to disperse and require ball milling, bead milling or bar milling. ball mills are used for small batches of difficult to disperse millbases.
