Fineness of Grind: Importance, Testing Methods, and Gauges

The fineness of grind is the degree of uniformity and extent of fineness to which particles/pigments are ground in paints and inks. Most of the pigments and extenders used in paints are processed to very fine particle sizes. This particle size ranges from 2 to 50 Microns. However, this fine size also needs to be:

Dry grinding is out of the question for safety reasons, as the fresh metal surfaces produced during the grinding process are extremely reactive. In the case of aluminum pigments, which are of ...

AN209 Pigment Size

grinding a pigment down to a fi ne, controlled particle size. This actually means two challenges. The fi rst is the grinding and the second is the measurement of the grinding results for effective process control. Here, we are primarily concerned with the latter. Pigment size can be readily measured by laser diffraction. This measurement

An investigation on optimum grinding system and

After some other processes, α-Fe 2 O 3 red powder particles -by-product of regeneration of spent pickling liquor in ARP in iron and steel industry- should be ground up to pigment grade to convert it to a value added product, red iron oxide pigment. In this study, grinding tests on α-Fe 2 O 3 red powder were performed using four different types …

Pigment Production

The ultra-fine grinding of pigments places high demands on the machine technology to be employed. The finest, absolutely grit-free granulation, low-residue processing with minimal contamination, as well as fast, thorough cleaning when switching products are the minimum requirements. Technical Article from NETZSCH published on process-worldwide ...

DISPERSANT PRODUCT GUIDE

The dispersion process of a pigment in liquid coatings can be divided into the three processes: Pigment wetting: The air and moisture covering the pigment is replaced by the resin solution. The solid/gas interface (pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage: By high shear forces the pigment

Grinding of Pigments | FrShop

As mentioned, once the water is poured into the center of pigment, I start to grind in a circular motion, and start to get a nice rhythm going along with the music, adding a little water as needed. After the initial grinding, I take a scraper and scrap the pigment back into a pile again, and begin the process once again and again.

Effects of type and duration of pigment milling on …

Grinding yellow pigment via wet process for 30 min reduced color purity as shown in Fig. 11, which is a result of initial agglomeration of particles due to inadequate time of milling. Considering the somewhat equal L*, C* and h* of WG60 and WG90 with YM, it is obvious that grinding FeO(OH) in water could not affect the C-SCM's color intensity. ...

Fine Grinding Of Carbon Black | Ink World

Typical high-speed dispersing with a sawtooth blade rotating at a shear rate of 600-800 sec-1 begins to de-agglomerate pigment particles. But for fine grinding of carbon black, high-speed dispersion does not completely de-agglomerate the particles. This is the purpose of the bead mill. The bead mill works like a filtering system.
