Core Technology & Working Principle
A ceramic pin type mill grinds by energy density rather than by chamber size. Pegs on the rotor interleave with stationary pins on the chamber wall, forcing the bead bed through dense shear planes on every revolution. Because the contact parts are sintered zirconia or silicon carbide, no iron is shed into the slurry even at the highest tip speeds — which is why the same machine can serve both white inks and conductive battery pastes without cross-contamination.
▲ 100% Metal-Free Ceramic Grinding Zone
Yttria-stabilized zirconia (ZrO²) or silicon carbide (SiC) replaces every steel component the slurry touches. For pure white digital inks, cosmetics and conductive pastes, zero metallic ion contamination is the difference between a saleable batch and a scrapped one.
▲ High-Energy Pin Rotor Geometry
To reach 50 nanometers, immense energy density is required. The horizontal pin rotor concentrates kinetic energy into 0.1–0.2 mm micro-beads, delivering the intense localized hydraulic shear needed to crush agglomerates without the beads compacting or stalling the motor.
▲ Dynamic Centrifugal Separation
A large-area dynamic centrifugal separator holds the bead charge inside the chamber while letting slurry leave at high flow. Because it separates by centrifugal force rather than a fine screen, it does not blind or clog with 0.1 mm micro-beads during high-throughput runs.
▲ Double Seal & Multi-Zone Cooling
A pressurized double mechanical seal with an independent barrier-fluid tank guarantees zero leakage. Spiral cooling jackets surround the entire ceramic chamber, extracting heat instantly to protect heat-sensitive organic pigments from thermal degradation.

PZB Technical Parameters
The table below summarises the standard PZB line-up used for ceramic and contamination-critical slurries. Batch handling figures assume a single-pass or short recirculation cycle; continuous multi-pass operation scales with feed pump capacity.
| Model | Working Volume (L) | Main Motor Power (kW) | Batch Handling (L/h) | Cooling Water Flow (L/h) |
|---|---|---|---|---|
| PZB6 | 6 | 15.0 | 100–200 | 1,000 |
| PZB10 | 10 | 18.5 | 200–500 | 1,500 |
| PZB20 | 20 | 30.0 | 300–600 | 2,000 |
| PZB30 | 30 | 37.0 / 45.0 | 500–800 | 2,000 |
| PZB60 | 60 | 75.0 | 600–1,500 | 2,500 |
| PZB150 | 150 | 160.0 / 200.0 | 800–2,000 | 4,000 |
