This guide compares bead mill vs attritor mill for paint: how each works, which products suit each and how to choose. Both grind pigment to a fine size after pre-mixing, but they differ in design, media and batch style.
Paint Manufacturing Machines supplies both and helps you choose from your product, batch size and fineness target. You may also search for this as bead mill or attritor, attritor mill for paint or horizontal bead mill vs attritor.
These guides come from hands-on paint factory planning, written in plain words for new and growing manufacturers. The advice on bead mill vs attritor mill comes from the hands-on consulting work of IPCS (Indian Paints Consulting Service).
How Each Mill Works
A bead mill pumps the pre-mixed paste through a chamber filled with small grinding beads that are stirred by a rotor. An attritor is a vertical tank with a central shaft and arms that stir larger grinding media together with the paste.
| Point | Bead mill | Attritor mill |
|---|---|---|
| Design | Closed chamber with rotor | Vertical tank with stirring arms |
| Operation | Continuous or recirculation | Mostly batch |
| Media | Small beads for fine grinding | Larger media, often for thick pastes |
| Suits | Fine grinds and gloss paints | Thick pastes and small batches |
Which Mill for High Gloss Paint
High gloss paints need a fine grind, so a bead mill is the common choice. It reaches a fine, narrow particle size on a continuous flow.
- Pre-mix on a high speed disperser
- Grind in a bead mill to the Hegman target
- Let down in a process tank
Mills for Small Batches
For small batches of thick paste, an attritor or a basket mill can be a practical choice. A basket mill fits on a disperser and changes over quickly.
- Attritor: thick pastes and small batches
- Basket mill: quick changeovers and small to medium batches
- Bead mill: continuous fine grinding
How to Choose
Choose from the product, not the machine name.
- Required fineness
- Viscosity of the paste
- Batch size and number of colours
- Cleaning time between batches
- Budget and space
