Choosing the Right Multi-Shaft High Speed Dispersing Kettle
How to ChooseSelect by viscosity and batch size: two shafts suit most viscous coatings and adhesives
Select by viscosity and batch size: two shafts suit most viscous coatings and adhesives, while a third improves turnover for stiffer products in larger vessels.
Size torque from the full rheology curve
Size torque from the full rheology curve, and specify jacketing, vacuum and discharge provisions at purchase rather than retrofitting them later.

Process Engineering
Working Principle
- 1
A multi-shaft dispersing kettle combines two or more agitators in one jacketed vessel, typically a high-speed dispersing shaft for shear and one or more low-speed anchors or scrapers for bulk movement.
- 2
The slow-speed agitators keep viscous material moving and sweep the vessel wall, preventing the stagnant insulating layer that would otherwise slow heating and cooling.
- 3
The high-speed shaft performs dispersion while the low-speed agitator maintains circulation, so the vessel handles viscosities beyond the practical range of a plain disperser.

Frequently Asked Questions
What mixing duties is the Multi-Shaft High Speed Dispersing Kettle designed for?
The Multi-Shaft High Speed Dispersing Kettle is built for Industrial Coatings, Adhesives & Sealants, Architectural Paints. It is selected when the batch has to be blended homogeneously without the shear damage a disperser would cause.
What viscosity range can it handle?
It works up to up to approximately 100,000 cP. Product-contact parts are Stainless steel 304 / 316L.
How is mixing uniformity achieved?
The agitator geometry keeps the whole batch moving rather than only the zone around the shaft, so colour, filler and additive distribution stay consistent from batch to batch.
What capacity range is available?
Capacity is 1,000 - 10,000 L, with motor power 15 - 110 kW. Vessel size is matched to the batch and the available floor space.
What discharge and cleaning options are available?
Bottom discharge, side discharge and hydraulic discharge arrangements are offered, with vacuum and jacket options where the formulation requires them.

What manufacturers say about working with POLYC MACHINE
These summaries reflect published application cases. Company names and roles are representative of the industries we serve.
The plaster and wall-material production line supplied by POLYC MACHINE integrated premixing, milling and transfer in one compact route. We reached consistent fineness across batches, and the local technical line made after-sales support responsive.
For our short gravure-ink runs, the small-batch grinding and dispersion route from POLYC MACHINE gave repeatable colour and fast changeover. The trial plan proposed before manufacture confirmed our fineness window without over-specifying the machine.
Our 1000L basket mill from POLYC MACHINE handles pigment and ink batches with the temperature control we needed for heat-sensitive formulations. Across multiple sites, the consistent basket-mill configuration simplified operator training and spare-parts planning.
