influence of pigment concentration and shear forces on the pigment dispersion were also studied. The procedure consisted of dispersing the pigment using a laboratory Dispermat® SL bead mill at various milling times with two different rotation speeds and measuring the particle size and particle size distribution of the milled samples.
DetailsBall milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.

The same pigment dispersion diluted with water shows particles of about 1 micron, dilution with a solvent shows agglomeration of particles (Picture 2). Besides Irgazin red, which is a rather large particle size pigment a wide selection of organic and inorganic pigments were dispersed.
DetailsBead Mills are machines for dispersion processing, where solid particles (pigments, fillers) are reduced in size and finely dispersed and wetted out in a liquid phase. Small ceramic, glass or metal beads are agitated inside the mill chamber to aid particle size reduction through impact and energy input while the dispersion is pumped through the ...
DetailsPigment dispersion can be a challenging process during the production of paints, coatings, and inks. Waterborne systems are particularly challenging due to environmental regulations, demand for premium color coatings, and cost considerations. Moreover, the quality of the dry paint film or ink is very much related to the uniformity of the distribution of the pigment.

DetailsPigment 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 agglomerates are broken up into smaller units, preferable primary particles. Stabilization: The pigment dispersion is stabilized …
DetailsThe tinting strength of the resulting dispersion was evaluated against that of a control sample prepared using a three-roll mill and which contained 40% pigment. Tinting strength was evaluated by the use of a white wax base that is fluid at 75° F., uncoated Leneta paper (3NT-1, the Leneta Company) and a color computer (X-Rite Corp.).
DetailsPigments are reduced in particle size as the inks are processed. Commercially, this can involve various processes from mixers, chip dispersion, ball milling, flushing, three-roll milling, sand mills, or vertical as well as horizontal bead mills.

DetailsTO DISPERSION DISPERSION OF PIGMENTS AND THE NEED FOR EFFICIENCY The primary objective of dispersing pigments in a dispersion or grinding medium by mechanical means, is to separate the pigment agglomerates which are formed during the drying processes in pigment manufacture. As particle size is reduced, the surface area so created increases, leading
DetailsPigment dispersions consist of an oil with a powder pigment in various concentrations. Dispersions are typically processed in a bead mill or triple roll mill in order to mix, refine and homogenize them. The quality of the resulting pigment dispersion impacts the overall performance of the lipstick since the oil contributes to sensory feel and ...
DetailsThe dispersion result is affected by the speed of the milling rotor, the size of the beads and the speed at which the product is passed through the mill. A bead mill can be used to disperse the product in either a single pass, or several individual passes, or be set up to continuously circulate the product which is known as re‒circulation ...
