A lab scale Fryma Co‐Ball mill ( L volume) is used and the effects of bead fill (4070%), flow rate ( kg/min) and rotor speed ( m/s) are investigated. Specific energy is the most effective ways to correlate performance to particle size suggesting that residence time (, flow rate) is the most important process parameter.

Blending is the process of mixing the added ingredients to meet product specifications. Blending may consist of additional milling in a ball mill, or added mixing and dispersing in a portable mix tank or highspeed disperser setup. Product Filling The final step in the paint and ink manufacturing process is the product filling operation.

There are many different types of grinding mills (Table 1). Some devices, such as ball mills, are more suitable for coarse materials. These mills use "large" media, ranging in size from 20 mm in diameter and up, to produce material from about ten microns to mesh sizes. Attrition mills are more appropriate for "midrange" size particles.

An agitator is a lowpowered, highvolume pump it is an efficient mixer. A typical dispersion application (such as dispersing pigment to make paint) requires about 1 HP for every 10 gallons compared to an agitator application (such as thinning the pigment dispersion with solvent), which requires about 1 HP for every 100 gallons.

DISPERSING TECHNOLOGY By the preparation of colored paint, a good dispersion quality is one of the most difficult factors. The dispersion process consists of converting dry pigments into pigment dispersion, which must be fine and sufficiently stable to achieve the final coloristic properties and stability.

"stirred ball mill." A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally ½" or larger, and run at a low (1050) rpm. The other mills, such as sand, bead

The use of effective pigment wetting and dispersion agents enables to increase the speed at which the liquid phase wets the pigment surface. This is valid to aqueous as well as nonaqueous millbases. A main contribution of dispersing agents is avoiding reflocculation of the freshly dispersed particles.

The "Attritor" is a stirred batch ball mill invented by Szegvari, now Union Process, of Akron Ohio. Here stirrer tips speeds, which rotate at moderately high speed, produce a regime of predominantly shear forces (rather than impact) and comminution is effected by "attrition" rather than cleavage as is the case in ball mills [ 9 ].
