Vertical Pin Type Bead Mill for Inkjet Digital ink
PZL Vertical Nano Bead Mill is a special mill used for difficult wet grinding tasks in recirculation mode. The vertical nano bead mill is mainly for middle and low viscosity of nanometer scale material grinding, the filter ink of liquid crystal display, inkjet, electronic pastes. The PZL vertical nano bead mill achievable particle size in the nano meter range for low to medium product, viscosity up to 1000 mPa.s
PZL Vertical Nano Bead Mill (High-Efficiency Pin-Annulus Vertical Grinding Mill)
Product Overview & Working Principle
A vertical bead mill is an advanced dispersion machine that utilizes high-speed rotation of a vertical pin-type shaft to agitate micro grinding media (ceramic, glass, or YTZ zirconia beads). The PZL series features an inner and outer peg-milling annulus, generating intense kinetic energy, shear friction, and high-frequency collision forces to refine pre-dispersed slurries down to sub-micron and nanometer particle size distributions.
Mechanical Dynamics & Media Separation
Slurry enters directly from the top inlet of the PZL Vertical Nano Bead Mill. The combined action of gravity and centrifugal force drives material continuously through the pre-dispersing zone and forced-displacement peg annulus. Dynamic centrifugal separation retains micro beads within the chamber while discharging processed product through a top-mounted removable protection screen on the inner stator—allowing screen maintenance without draining the milling chamber.
Key Technical Features
- Top Product Inlet: Slurry feeds directly into the top of the PZL vertical grinding chamber, eliminating bottom seal pressure accumulation.
- Inner & Outer Peg Milling Annulus: High-density pin/peg rotor and stator design concentrates energy input for micro media in the 0.2 mm to 1.5 mm range.
- Internal Media Recirculation & Centrifugal Separation: High-efficiency dynamic separator keeps micro beads evenly fluidised without screen clogging or bead compression.
- Multi-Zone High-Efficiency Cooling: Independent chilled water jackets cool the rotor, outer stator, inner stator, and chamber bottom to keep heat-sensitive products within strict thermal limits.
- Screen Removal Without Draining: Removable protection screen on top of the inner stator can be inspected or cleaned without draining slurry or beads from the mill chamber.
