Pigment compositions prepared from a pigment, a hydroxylic solvent, and a polar polymer may be reduced in particle size by grinding in the absence of a salt to produce a pigment which may be used quot;as isquot; without any subsequent treatment.
Pigment wetting: All of the air and moisture is displaced from the surface and between the particles of the pigment aggregates and agglomerates (clusters) and is replaced by the resin solid/gaseous interface ( pigment/air) is transformed into a solid/liquid interface (pigment/resin solution).
#0183;#32;Using this method, submicronsized pigment particles (approximately 190 nm) were obtained after milling for 4 h. Planetary milling was more efficient in reducing particle size in the same milling time compared with attrition milling. The coprecipitated pigment had a more intense black colour due to its nanoscale particle size (lt;100 nm).
Attrition Mills from Munson Machinery are ideally suited for reducing fibrous and friable materials within a relatively narrow particle size range from coarse down to 100 mesh. The replaceable milling plates are offered in several patterns to optimize size reduction for specific types of materials.
attrition fine dry milling using Attritors in continuous or batch type modes. The principle of Attritor dry grind processing is achieved by an expanded moving bed of media. This condition is described as kinematic porosity. The dry particles are subjected various forces

nanosized pigment particles described in a series of Kodak patents. The Kodak patents describe milling process in which pigment particles of a primary particle size of 150 nm are reduced to less than 50, 2 However, the Kodak patents do not describe the mechanisms by which particles breakage and milling occurs. The patents also neglected

In order to disperse a pigmented filtercake, break up the pigment into fine particles suspended in water, a mixture of filtercake, water and a stabilizer are subjected to ice particles. The mixture of ice particles, filtercake and water are then agitated and the particles of ice act as an abrasive to break up and disperse the pigment.
Generally, in accordance with the present invention, the crude dry pigment is charged to an apparatus having attrition and shearing action, such as a conventional ball mill, along with steel balls, rods, etc. Ordinarily, the ratio (wt) of balls to organic pigment is about 20/1, but may range from about 550/1.
The four basic techniques used in size reduction of dry powders are impact, shear, attrition and compression forces. In some cases, a combination of these may be found in a single mill type. Impact and attrition sizereduction methods include air classifying mills, pin mills, hammer mills and jet mills.
The attrition and shearing action desired for milling crude organic pigments to develop pigmentary properties may be accomplished in ball mills or rod mills of the rotary drum type, stirred or vibratory types. The grinding media used in ball or rod mills are preferably hard metal or ceramic grinding elements of about to 2 cm. diameter.

#0183;#32;To investigate the effect of mill type on the milling performance of the CoFe 2 O 4 pigments, attrition milling was also performed. As shown in Table 2, the BET particle size changed from 670 nm to 560 nm and 465 nm after 1 h and 4 h of milling, respectively. The SEM images of the attrition milled pigments are presented in Fig. 7.
