All pigments were ground for at least an hour by a bead mill, and all pigment tints achieved fineness of grind readings of 2.5 µm or better at the end of grinding. The tinting strength of all non-white pigment concentrates was evaluated using a white-base formula W-Base (Table 3), which was based on Polyol 6810.
Pigment and Dye Applications for Wet & Dry Grinding Mills. Pigments and dyes both change the perceived color of an object by altering reflected and absorbed light – the varying wavelengths of light that are reflected produce the color that is seen. Both have also …

Choosing The Best Media Mill For Your Wet Grinding. Jul 01, 2003018332Fortunately for the pigment and coatings industry, there are a wide variety of media mill manufacturers and technologies from which to choose. Besides conventional vertical and horizontal media mills, there is a vast array of high-performance media mills on the market.
grinding media needs to be considered as this can lead to contamination of the dispersion (12-15). The optimum milling process parameters, i.e., the milling time and the milling speed, to prepare pigment dispersion depends on a number of factors including the pigment hardness,

before loading it into mill. There are several types of grinding media generally used in the Attritor. They are, to name a few, carbon steel, chrome steel, stainless steel, tungsten carbide, ceramic, alumina, zirconium oxide, glass, (flintstones,) and specials such as silicone nitride and silicone carbide. The carbon steel grinding media (Sp.gr ...
Pigment dispersion process by using a bead mill is the . major energy-consuming process during the manu-facturing of water-based ink. Milling process param-eters like milling time, size and density of grinding media (GM), pigment loading, and speed of machine are majorly affecting the pigment particle size distri-

Add the pigment, in stages, and disperse in the normal manner. In case you want to optimize a Polymeric dispersant millbase, 4 stages are involved. The following example explaining using Avecia Solsperse products (referred to as a ladder series). Stage 1 - Calculation of % AOWP of Polymeric hyperdispersant.
Grinding the pc pigment in water using a media mill. mostly, dispersions of pc in water are used in heat-set inks to make the color phthalo blue. typically, pc slurries are 40-50 solids and ground with steel media spherical beads to produce a stabilized dispersion with 99.9 percent of all solid particles less than 0.5 microns in size.
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.

What are immersion mills, and why are they a popular choice in the wet milling and grinding industry? Immersion mills, also known as basket mills, are submersible milling units that allow for effective particle size reduction without the use of elements like pumps, hoses, and tanks, which can be maintenance-intensive and difficult to clean.
Rh series horizontal mill the red head horizontal grinding mills available from lab to production sizes suitable for use with glass and ceramic grinding media grinding media as small as 03 mm advanced design features to be rolled out soon.
The selection of the grinding media depends upon the nature of the pigment, viscosity, desired particle size of the finished product, color and appearance requirements (gloss, haze, color strength, transparency). The residence time or dwell time is the time required for the product to pass through the mill. If the dwell
Most pigments used in inks and coatings, for instance, have a primary particle ... A fine bead mill with grinding media on the order of 100 microns ( m) to 200 m is the simplest, most scalable, most cost-efficient way to make and disperse nanoparticles, though this
