Product Overview
How it works
A high-speed rotating disc creates shear and circulating flow in the liquid or slurry. Powder is wetted and dispersed into the liquid phase. This is typically a pre-dispersion step rather than a substitute for fine grinding.
How to choose a disperser
Provide the material and solvent system, viscosity, batch volume, tank dimensions, required dispersion result, installation layout, and safety requirements. Match the motor, disc, shaft, and lifting arrangement to these conditions.
Disperser vs. bead mill vs. planetary mixer
For further particle-size reduction, evaluate a laboratory bead mill before selecting a production mill. For high-viscosity bulk mixing, evaluate a double planetary mixer. A larger motor alone does not make these processes interchangeable.

Technical questions
Frequently Asked Questions
What process does a high-speed disperser perform?
A rotating disc creates shear and circulation for powder wetting, pre-dispersion, mixing, and homogenization in suitable liquid or slurry systems.
What standard power range is available?
The GFS-RN model table lists motors from 1.5 to 37 kW. Configuration depends on material properties and required batch size.
What is the shaft speed?
The usual range is 0–1500 rpm with variable-frequency control. Selected or customized models can support 0–3000 rpm; this is not a standard rating for every model.
Can the lifting method and shaft be customized?
Yes. Hydraulic or mechanical lifting and single- or double-shaft configurations can be selected for the process.
Are explosion-protection options available?
Yes. Motors, controls, and other provisions can be specified for the solvent system and site requirements. Applicable standards and certification scope must be confirmed for the project.
How is a disperser different from a bead mill?
A disperser primarily wets and pre-disperses powders. A bead mill provides further grinding and particle-size control. The two are often used in sequence.
Can it be integrated into a production line?
Yes. A project can combine dispersers, bead mills, tanks, filtration, and controls according to the required process.
Are all dimensions and weights fixed?
No. The tables provide initial reference data. Entries marked Customizable require project confirmation, and final values depend on configuration.
