| Résumé : |
Wet grinding in bead mills is a key process step in the production of coatings. Factors affecting product quality and productivity are discussed. It is shown that significant improvements may be obtainable by coordinating the size, density and quality of the grinding beads used to the product and mill type. |
| Note de contenu : |
- How colour properties are linked to dispersion
- Full volume bead mills need large grinding beads
- Smaller beads in a different mill improve efficiency
- Why bead quality is an important factor
- Top quality beads may not always be needed
- Beads and materials exactly matched to the product
- FIGURES : 1. Simplified schematic of a full volume bead mill process chamber - 2. Simplified schematic of annular gap mill process chamber - 3. Grinding beads are supplied in a very wide range of sizes, shown here enlarged for comparison purposes
- TABLE : How bead density and diameter are related to product viscosity for efficient milling (guidelines only : energy input and local shear rate in the mill may change viscosity significantly). |
