This guide explains high speed disperser selection for paint: how to match motor power, blade and vessel size to your batch and viscosity. It uses sizing rules published by PCI Magazine for high speed dispersers.
Paint Manufacturing Machines sizes a disperser from your batch volume and viscosity and checks the choice in a trial. You may also search for this as how to select disperser, disperser size for paint or disperser motor power for batch.
These guides come from hands-on paint factory planning, written in plain words for new and growing manufacturers. The advice on high speed disperser selection comes from the hands-on consulting work of IPCS (Indian Paints Consulting Service).
Sizing Rules From Industry Guidance
PCI Magazine gives these rules of thumb for a high speed disperser. Your own product and trial results fine-tune them.
| Item | Guideline |
|---|---|
| Blade diameter | About one third of the vessel diameter |
| Blade tip speed | About 4,800 to 5,200 feet per minute |
| Motor power | About 1 HP for every 10 US gallons of batch (roughly 38 litres) |
| Viscosity | About 1,000 to 25,000 cP, and up to about 50,000 cP with care |
Disperser Blade and Vessel Size Ratio
A blade about one third the diameter of the vessel creates a flow pattern that pulls material down into the blade. A blade that is too small does not move the whole batch, and a blade that is too large wastes power.
- Pick the vessel from the batch volume
- Choose a blade at about one third of the vessel diameter
- Set the blade height as the maker advises
- Confirm the pattern in a trial
Disperser Motor Power for Batch Size
Motor power follows the batch volume and the viscosity. The rule of about 1 HP for every 10 US gallons is a starting point. Thicker batches may need more power, and thin batches may need less.
- Larger batch means more power
- Higher viscosity means more power
- A variable speed drive helps with both grind and let-down
Selection Checklist
Confirm these points before you order.
- Batch volume and viscosity
- Vessel and blade size
- Motor power and speed range
- Material of construction
- Flameproof option for solvent products
- Lifting and safety guard

Frequently Asked Questions About high speed disperser selection
How to choose a high speed disperser for paint?
Match the vessel to the batch volume, set the blade at about one third of the vessel diameter, size the motor from the batch and viscosity, and run a trial.
How to select disperser speed for paint?
PCI guidance gives a blade tip speed of about 4,800 to 5,200 feet per minute for good dispersion.
What disperser size for paint should I pick?
Pick the size from the batch volume. The blade is about one third of the vessel diameter.
What is the disperser motor power for batch of 1,000 litres?
The PCI rule of about 1 HP per 10 US gallons gives a starting point. Viscosity and speed range change the final size, so we confirm it in a trial.
What is the disperser blade and vessel size ratio?
The blade is about one third of the vessel diameter.
What is the disperser motor power for batch size planning?
Use about 1 HP for every 10 US gallons as a starting point, then adjust for viscosity and speed range.
Do you test the disperser on my product?
Yes. We can run a trial on your formula to confirm the size.
