PRODUCTS – HIGH ENERGY BEAD MILLS
High Energy Bead Mill Manufacturer in India
KRS DISPERMAHLTECHNIK manufactures high energy bead mills for wet grinding and fine dispersion of pigments in paints, printing inks, coatings and chemicals.
OVERVIEW
What is a high energy bead mill?
A high energy bead mill is a wet grinding machine: an agitator sets grinding beads in a closed chamber in intense motion, and the beads reduce the particle size of the pre-dispersed product. Bead mills are the industrial milling equipment used after pre-dispersion when a product needs a finer, more uniform particle size than a disperser alone can achieve – for example in paints, printing inks and coatings.
HOW IT WORKS
How bead milling works
Grinding chamber
The pre-dispersed product is pumped through a closed horizontal chamber filled with grinding beads.
Bead motion
An agitator sets the beads in motion; impact and shear between them break particles down.
Separation
A separation system at the outlet retains the beads while the finished product leaves the chamber.
CONSTRUCTION
Machine construction and key features
A KRS bead mill combines a horizontal grinding chamber with an agitator, a drive in the machine base, a product feed and a media separation system at the chamber outlet. Pressure gauges on the product circuit and a control panel at the machine let the operator monitor the process.

What is a high energy bead mill?
A wet grinding machine in which an agitator moves grinding beads inside a closed chamber. The beads reduce the particle size of solids dispersed in a liquid, giving a fine and uniform dispersion.
What is a bead mill used for?
For wet grinding and fine dispersion: reducing the particle size of pigments and other solids in a liquid to a defined fineness, for example in paints, inks, coatings and chemical products.
How does a bead mill work?
The pre-dispersed product is pumped through a chamber filled with grinding beads. An agitator moves the beads, impact and shear between them break particles down, and a separation system keeps the beads inside the chamber.
What materials can be processed?
Liquid, pumpable products containing solids – pigment dispersions, paints, liquid printing inks, coatings and chemical suspensions. Very high-viscosity pastes are usually better suited to a three-roll mill.
How does bead milling reduce particle size?
Through repeated impact and shear between the moving beads. Bead size, agitator speed and the time the product spends in the chamber determine the final fineness.
Bead mill or three-roll mill – which do I need?
Bead mills suit liquid, pumpable products in continuous operation; three-roll mills suit high-viscosity pastes such as paste printing inks.
What information is required for a bead mill quotation?
Your product and application, viscosity and solids content, required throughput, target fineness and the operating environment – for example whether flameproof execution is needed.
