High Speed Disperser Selection & Applications
Assess material, batch, viscosity, air/VOC requirements and development stage before choosing a configuration.
Below 3,000L: PDM, PDH or PVM. 3,000L and above: PSD platform; one head can serve 1–4 vessels with 360° rotation.
Low viscosity: PDM single-shaft. Medium-high viscosity or high solids: PDH double-shaft.
For deaeration or reduced solvent volatilisation: PVM vacuum, ≤-0.09MPa.
Start with laboratory models, maintain D/T≈0.33 and 20–25m/s tip speed, then scale to production.
220/380/415/440/460V, 50/60Hz; SS304/SS316; single/double jacket; flat or domed cover; clamp, scraper and dust cover options.
Decision table
Match your process to the right disperser.
| Question | Selection |
|---|---|
| Water-based or solvent-based? | Water-based: standard motor; solvent-based: full explosion-proof configuration. |
| How large is the batch? | <3,000L: PDM / PDH / PVM; ≥3,000L: PSD. |
| What is the viscosity? | Low viscosity: PDM; medium-high viscosity: PDH. |
| Is deaeration required? | Yes: PVM vacuum disperser. |
| Before mass production? | Start with a laboratory model for linear scale-up. |
