Mill Pigment Dispersion

What is Dispersion Equipment | Custom Milling & Consulting ...

They specialize in particles size reduction and dispersion technology. Equipment: Horizontal Media Mill; SHRED in-line rotor stator; Batch Mill; Multi-shaft Mixer; Lab Mixer; Planetary Mixer; Dispersion equipment takes particles and breaks them down to create homogenous mixtures of materials.

Laboratory & Pigment Dispersers by BYK-Gardner

If solids, especially pigments, are not broken down into smaller particle sizes and spread evenly throughout the liquid base during the paint manufacturing process, the result is a poor paint quality.

Ball Milling The Role of Media and Bead Mills - BYK

The mill base and grinding media is mixed 50/50 in the container. A disk impeller or pearl mill impeller is immersed into the mixture and rotated from 500 to 5000 RPMs depending on the desired particle size. After the dispersion is completed the stop cock that covers the sieve filter is removed, the lid is clamped tight over the vessel.

Baket Mill | Baket Mill for paint and Pigment Dispersion ...

Wahal Engineer’s manufactured Mills has a redefined batch dispersion system. This design insures materials to pass through the high density dispersion zone within the milling chamber at a high frequency. This system offers a high degree of dispersion which can be many times more efficient than traditional media milling systems.

Colloid Mill Case Study - Pigment Dispersions | Sonic ...

The Solution: A Lab Scale Colloid Mill After initial trials at the Sonic lab  which showed improvements in the pigment dispersion and eliminated the inconsistent color, Sonic recommended a 2.5” lab scale colloid mill for the dispersion application.   This scale colloid mill would more than handle the low volume demand for colorant.

Pigment Production - NETZSCH Grinding & Dispersing

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.


1. Wetting of the pigment particles by the fluid components of the mill base 2. Breakdown of the associated particles (agglomerates and aggregates) leading to smaller particle sizes 3. Stabilization of the dispersion preventing renewed association (flocculation) Pigment particles can be divided into three classes: Primary particles = crystal

How to disperse and stabilize pigments

Mechanisms in the dispersion process Pigment wetting : All of the air and moisture is displaced from the surface and between the particles of the pigment aggregates and agglomerates (clusters) and is replaced by the resin solution.

A Practical Guide to High Speed Dispersion

An agitator is a low-powered, high volume pump - it is an efficient mixer. A typical dispersion application (such as dispersing pigment to make paint) requires about 1 HP for every 10 gallons compared to an agitator application (such as thinning the pigment dispersion with solvent) requires about 1 …

Cosmetic Three Roll Mill

Pigment dispersion is the most important step. The finer the pigment is ground, the higher the gloss achieved, and the more stable the finished product. The required pigment is blended with nitrocellulose in a mix of bentone solution and plasticizer. The resultant is then ground through a three-roll mill,...

The Study of Ink Pigment Dispersion Parameters

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.

Bead Milling | Material Milling | Dispersion Processing ...

Bead 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 mill.

Comparison of methods to assess pigment dispersion ...

Dec 01, 2001 · One pigment is more difficult to disperse than the other in the vehicle used. The five methods that could detect changes in dispersion with each pass over a three-roll mill were a light scattering particle size distribution analyzer, a NPIRI fineness of grind gauge, gloss, contrast ratio measurements, and rheology.

This will result in the dispersion of pigment through impact rather than shear, decreasing the cleanliness of the color development and the gloss of the product. Over-filling of the basket may reduce throughput, draw more amperage, increase milling times, and increase wear on both the mill and media.
