Grinding stage: By high shear forces the pigment agglomerates are broken up into smaller units, preferable primary particles. Stabilization: The pigment dispersion is stabilized by dispersing agents in order to prevent the formation of uncontrolled flocculates. The resultant suspension is stabilized due to the

Wet and dry grinding are the two most common and effective milling methods, and both have advantages, disadvantages, and specific challenges that can complicate processes. Whether a product goes through a wet grinder or a dry grinding process depends on multiple factors, including raw material, target particle size, particle surface and shape ...

Deagglomeration is achieved through the use of mechanical energy developed by the use of high-speed dispersers and various types of grinding equipment. A Cowles blade fitted on the shaft of a high-speed mixer can be an efficient means of dispersing a pigment.
The better the dispersion before taking the product over to the mill the more productive the milling cycle will become. Poor premixes cause longer grind times (higher production cost), plugged screens (more down time and product loss) and greater wear on the mill (higher maintenance cost).
Attritors or stirred ball mills are a simple and effective method of grinding and dispersing fine and homogenous material quickly. The Attritor can operate wet or dry, introduce inert atmospheres, operate at controlled temperatures, and vary grinding speed. Results are repeatable from one grind (batch) to another so the attritor is ideal for ...
This paper focuses on pigment families and their application in waterborne, solventborne and universal dispersions. The theory behind processing, selection of wetting and dispersing agents, and the differences between co-grinding and single pigment dispersion are discussed. Pigments vs. Dyes--Is Solubility Important?
The problem could be that gap between the teeth is not optimal. The study shows that cavitation presses, which create irregular high-speed jet streams and shock waves, are very effective at dispersing this grout. The additive used also had a positive influence on the dispersion with ultrasound but not in dispersion with conventional dissolver.
Grinding / dispersing time reduction Anti-sedimentation Effective against flooding and floating Action mode: Mainly electrostatic, few steric hindrance Recommended for inorganic materials and waterborne systems suitable for organic pigments Surfactant type - They have an excellent compatibility and excellent water dispersibility.

The wetting step of dispersing processes can be intensified by the use of wetting agents and/or binders with lower viscosity and surface tension. On the other hand, a resting of pigment/binder premixes prior to their dissolving or grinding helps to accomplish the wetting stage and always eases and accelerates dispersing processes. Grinding stage
An effective additive can help to significantly shorten the grinding time and thus save time and money. In addition, the performance of the wetting and dispersing additive can make a significant contribution to an optimal overall result. Apart from helping to develop gloss and color strength, the dispersing additive also plays a decisive
One drawback is that dry grinding machines' capacity is greater than that of the wet grinders. This makes wet ground mica more expensive in the marketplace. One of the characteristics of mica is that grinding produces flaky powders with high aspect ratio which is the most important factor and determines the performance of particle
The dispersing agent should be effective under the dyeing conditions and should be stable to hard water, high temperature and other dyeing assistants. Soap powder, Turkey Red Oil, Alkylsulphates, Alkylarylsulphonates, Fatty Alcholethylene Oxide condensates, Naphthalene-β-sulphonate and formaldehyte etc are the recommended dispersing agent ...

Even so, the energy associated with the surface is a small proportion of the total involved. Because of this it is difficult to see how the reduction of the surface energy can significantly affect the energy required for grinding but, nevertheless, surface active dispersing agents are often very effective grinding aids.
size from 20 to 200 nanometers, meaning that many operators of bead mills are already grinding and dispersing in the nano range. However, there exist real difficulties in the effective design, development and delivery of nanoparticles, most particularly in the area of dispersion. Just as the benefits of nanoparticles are
Dry and wet grinding are two common and effective grinding methods. Usually, in the machine used for dry grinding, the material will contact and hit other particles or rotors in a closed area until it is broken into the required size. Dry milling can make particles reach micron size. But if you want to achieve smaller nanometer sizes, wet ...
