Grinding Pigment Involves

Pigment grinding or milling entails the incorporation of the pigment into the liquid base of the coating to yield a fine particle dispersion. The three stages of this process include wetting, grinding, and dispersion, which may overlap in any grinding operation. The wetting agent, normally a surfactant, wets the pigment particles by displacing ...

involves four major steps: preassembly and premix, pigment grinding/milling, product finishing/blending, and product filling/packaging. Some of the equipment used to accomplish these manufacturing steps include roller mills; ball and pebble

In general the colour of the ink arises from organic pigments; the particle size of the pigment governs the colour intensity. Milling is carried out in two stages: the primary mixing is done with an ordinary mixer and the resultant pre-mix is subjected to secondary grinding in a ball mill or a roller mill.

Of importance in wet grinding, fimedia millsfl or agitator mills use grinding media (spherical beads) tailored for both size and material to disperse the solids. One of the more common organic pigments used for printing ink is phthalocyanine (Pc). An organic pigment is a dry powder often used as a coloring agent or colorant in printing inks.

Pigment dispersant system and method for pigment grinding

The pigments that can disperse in this method are very limited for color. Deep rich color tones are rarely achieved. 3. Base Intermix Tinting: Base intermixing involves the mixing of clear “non-pigment” components of a paint formula with pre-dispersed pigments that are purchased or manufactured on site.
