Grinding Particle Dispersion
Wet Milling Machine | Custom Milling & Consulting
Wet milling machines, including horizontal media mills, submersion-type basket media mills and high-shear dispersers, are used for the grinding of wet applications for particle size reduction. Grinding and dispersion operations have advanced dramatically over …
Dispersing agents - Functionality & Performance ...
The grinding process incorporates these solid materials into the liquid vehicle or grinding resin. During this process, the agglomerates are transformed into a dispersion of particles, which can be as small as the primary particle size.
Wet Grinding/Milling Beads - Products - Ceroglass
Back to topic overview Wet Grinding/Milling Beads Wet Grinding/Milling/Dispersion Media Grinding and Dispersions are employed in almost every industry. This demonstrates our extremely broad range of media applications, primarily in the areas of: Paint Pigments/Dyes Printing Inks ...
The Importance of Particle Size in Liquid Coatings ...
The stability of pigment dispersion is improved through particle size reduction in three ways: Rheology and/or viscosity. Reducing pigment particle size increases pigment surface area, which usually results in increased viscosity.
AN209 Pigment Size - Horiba
Pigment Size AN209 Pigment Particle Size and Hiding Power Particle size is intimately related to hiding power in pigments. Due to its speed and wide size measurement range, laser diffraction is an ideal tool for tracking the grinding process and therefore controlling the resulting pigment performance.
A Practical Guide to High Speed Dispersion
Horsepower requirements are interrelated with blade diameter, tank diameter, batch size, rheology, viscosity and density. Variations outside recommended operating parameters usually result in compromises in performance such as poor particle separation, extended dispersion times, and a decrease in quality of the finished product.
High Shear Dispersion Grinder Pump (DICONS)
The grinding action is continuously repeated as the materials move toward the discharge port. An optional discharge grid plate with a precisely positioned series of venturi-type orifices from 1/32" to 3/4" I.D., provides positive particle size control. Materials must exit through one of the small precision ports.

Grinding time is related to media diameter and agitator speed via: T = KD2/N½ where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm.
Inline Emulsifier Mixer - Quadro® Liquids
Inline Emulsifier Mixer The Quadro Ytron ® Z Emulsifier delivers unparalleled consistency and control of high shear process applications such as emulsifying, wet milling or grinding, suspension deagglomeration, texturizing and fine particle dispersion.
Nanoparticle Grinding and Dispersing - Ceramic Industry
Today, most pigments used in inks and coatings have a primary particle size from 20 to 200 nanometers (nm), and materials smaller than 100 nm are increasingly being used in advanced ceramic applications, meaning that many operators of bead mills are already grinding and dispersing in the nano range.
Effectively Grinding And Dispersing Nanoparticles …
years, the use of fine bead mills for grinding and dispersion of these particles has become more and more prevalent. Fine bead mills, widely used in both laboratory and production applications, deliver an efficient method for the grinding and dispersion of nanoscale particles from 20 to 200 nanometers.
Using an agitator bead mill for nanoparticle …
two ways — mild dispersion and real comminution. The difference between mild dispersion (disaggregation or deagglomeration) and real comminution (reducing parti-cles below their primary particle size) is a matter of energy input. This energy input is largely a function of the periph - eral speed of the agitator shaft that drives the grinding media.
Formulating and Processing Pigment Dispersions
dispersion starts with three primary ingredients: a grinding vehicle, a pigment, and almost always a surfactant. The choice of these three items is where the formulation process begins. A dispersion is defined to be the ultimate state of homogeneous1 suspension of one phase with another.
DISPERSION - BYK Additives & Instruments
Dispersion equipment can be divided into two classes: 1. Equipment without grinding material: Dissolver 2. Equipment with grinding material: Bead mills, attritors, ball mills High speed dissolvers: Dissolvers are used for easy to disperse pigments, most inorgan-ics, and for pre-dispersion and wetting of hard dispersible pig-ments.

Ultrasound for Dispersing and Grinding: Paint & Pigments
Dispersion of Nanoparticles. Ultrasonic grinding and dispersing is often the only method to process nano particles efficiently in order to obtain primary particles. A small primary particle size results in a large surface area and correlates with the expression of unique particle characteristics and functionalities.
