Choosing the Right Low Speed Mixing Vessel (PMK Series)
How to Choose1
Use for standardisation
Use for standardisation, letdown and storage duties after dispersion or milling, not for grinding.
2
Size by batch volume and required temperature control; specify jacketing where viscosity specifications are tight
Size by batch volume and required temperature control; specify jacketing where viscosity specifications are tight, since viscosity is temperature dependent.
3
Confirm with POLYC
Confirm contact materials and documentation (CE) with your order specifications.

Process Engineering
Working Principle
- 1
A low-speed mixing vessel uses a slow-running agitator, typically an anchor or paddle, to blend finished product by bulk convective movement rather than high shear.
- 2
Because the pigment is already dispersed, the objective is uniform blending and temperature maintenance without incorporating air.
- 3
A jacketed wall provides heating or cooling, and the gentle action preserves viscosity and stability in products that would be damaged by high shear.

Frequently Asked Questions
What mixing duties is the Low Speed Mixing Vessel (PMK Series) designed for?
The Low Speed Mixing Vessel (PMK Series) is built for Architectural Paints, Industrial Coatings, Adhesives & Sealants. 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 low to medium viscosity. 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 2.2 - 18.5 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.
