Start With the Material
A suitable disperser is selected by batch volume, viscosity, pigment system, target fineness and working environment—not motor power alone.
Send your formulation details.
We will help evaluate the appropriate series and options.
Control the Dispersion Stage That Shapes Product Quality
In paint, coating and ink production, pigment wetting and deagglomeration influence color development, gloss, hiding power, stability and the appearance of the finished film.
YAKU high-speed dispersers use a rotating dispersing blade to generate shear and material circulation. The machine, blade, speed and vessel geometry should be matched to the formulation so operators can establish a repeatable process from laboratory development through production scale-up.
Pigment Wetting
Promotes contact between liquid ingredients and pigment agglomerates.
Process Repeatability
Variable-speed control helps operators reproduce established batch parameters.
Flexible Scale-Up
Choose laboratory, pilot or production equipment for each development stage.
Three Disperser Series for Different Batch Sizes
Use these ranges for initial comparison. Final capacity and performance depend on the formulation, blade, vessel and operating conditions.

Process Features for Ink, Coating & Paint Production
High-Shear Dispersion
Cowles-style blades support pigment wetting and deagglomeration. Blade selection should reflect pigment type, viscosity and the required endpoint.
Repeatable Speed Control
A variable-frequency drive allows controlled speed adjustment and helps standardize operating parameters between batches.
Optional Vacuum Processing
A sealed configuration can help remove entrapped air and limit exposure during suitable processes. Results depend on the material and system design.
Hazardous-Area Configuration
Explosion-protection requirements must be defined from the solvent, area classification and applicable local standard before equipment is specified.
Cleaning & Changeover
Accessible shafts, blades and smooth wetted surfaces can simplify cleaning when changing colors or formulations.
Configurable Construction
Select wetted-part material, seals, vessel design, controls and accessories according to compatibility and production needs.

Frequently Asked Questions
Should I select a disperser by vessel capacity?
No. Working volume is only one factor. Viscosity, pigment loading, target fineness, blade diameter, speed and vessel geometry should be considered together.
When is an explosion-protection configuration required?
That decision depends on the material, vapor, installation area classification and applicable local rules. Provide this information before the electrical and mechanical configuration is confirmed.
Can one disperser handle different colors and products?
A suitable quick-change and cleaning arrangement can support multi-product use. The cleaning method and wetted-part compatibility should be reviewed for every formulation.
Do I need vacuum de-aeration?
Vacuum may help when air entrapment affects processing or finished-product quality. Whether it is appropriate depends on viscosity, volatility, foaming behavior and the desired result.
