Description
How it works
The PZB 20L Pin Type Bead Mill is a medium-capacity horizontal wet grinding mill for ink, paint and pigment production. It uses a pin-type rotor to accelerate grinding media and applies impact and shear to reduce particle size. The centrifugal separation system retains beads down to 0.3mm while allowing the finished slurry to pass through. Force cooling on the grinding cylinder, rotor and discharge end face controls material temperature. This model is commonly used for ink and pigment formulations requiring fineness below 5 micrometres.

| Material Type | Target Particle Size | Recommended Bead Size | Viscosity Range |
|---|---|---|---|
| Industrial coatings | 5-15 μm | 1.5-2.0 mm | Medium |
| Ink / pigment paste | 1-5 μm | 0.8-1.2 mm | Low to Medium |
| Battery materials | < 1 μm | 0.4-0.8 mm | Medium |
| Agrochemical SC | 3-10 μm | 1.0-1.5 mm | Medium |
Typical reference values only. Actual results depend on formulation, bead material, and process conditions. Material testing is recommended before final selection.
Equipment Selection
Selection Principles
- ✓
Select chamber size from sample volume, available material, target fineness, and scale-up objective.
- ✓
Confirm grinding-media material and diameter against contamination and separator limits.
- ✓
Record specific energy, temperature, flow, and pass count so trials can support production scale-up.
Process Engineering
Working Principle
- 1
A small charge of premixed slurry circulates through the media-filled laboratory chamber.
- 2
The rotor accelerates the beads to generate impact and shear while cooling limits temperature rise.
- 3
The separator retains media and allows samples to be collected for particle-size and formulation analysis.
Equipment Benefits

Frequently Asked Questions
What is a basket mill?
A basket mill is a submersible wet grinding machine that combines premixing, dispersion, and grinding in one vessel. POLYC MACHINE basket mills support laboratory and production batches for coatings, inks, and battery materials.
Basket mill vs horizontal bead mill?
Basket mills are submersible and suit small-to-medium batches with easy cleaning. Horizontal bead mills are continuous-flow machines for higher-volume production. POLYC MACHINE engineers can recommend the right configuration.
What capacity range do your bead mills support?
POLYC MACHINE bead mills range from laboratory models to 1,000 L production machines. Custom configurations are available for specific materials, viscosity, and throughput requirements.
What materials are bead mills suitable for?
Our bead mills process coatings, inks, battery materials, pharmaceuticals, cosmetics, agrochemicals, advanced ceramics, and chemical products. Material testing can be arranged before purchase.
How do I choose the right bead mill?
Consider batch size, material viscosity, target fineness, and production volume. POLYC MACHINE engineers provide consultation and material testing to recommend a suitable machine.
