Nano Grinding Agitator Bead Mill WMS30 30L 22kW For European Inkjet Ink Milling

The WMS30 agitator bead mill is a 30-litre nano grinding unit designed for formulators who need reproducible sub-micron dispersion rather than bulk throughput. With a 22kW motor and a chamber that accepts 0.3 to 1.2 mm zirconia beads, the agitator shaft accelerates the bead charge to a high energy density and typically reaches a median particle size of 150 to 300 nanometres on pigment concentrates, inkjet inks and electrode slurries, while jacketed cooling holds outlet temperature to within about two degrees of set point. The working volume makes it practical to run 20 to 50 litre batches for customer sampling and pre-production validation, and the specific energy per litre matches the larger agitator bead mill chambers, so scale-up to 60L or 150L does not require redeveloping the recipe. European ink and battery material developers use the platform for colour concentrate milling, carbon black and organic pigment dispersion, and for verifying bead life and contamination levels before committing to a full production line.

• Agitator Bead Mill Nano Grinding: a high-speed agitator disc stack paired with 0.3-1.2 mm zirconia media delivers D50 values down to roughly 150 nanometres on hard organic pigments
• Tight Temperature Stability: the jacketed chamber and low working volume keep outlet temperature within about two degrees, protecting heat-sensitive ink resins and binder systems
• Ceramic-Lined Option: a ceramic or polyurethane-lined chamber can be specified where metal contamination must stay below detection limits for electronic or battery applications
• Recipe Transferability: specific energy input per litre is matched to the larger agitator bead mill chambers, so a validated 30L trial scales to production without reformulation
• Low Product Hold-Up: the 30L working volume limits dead stock during colour changes, which matters when a formulator runs many small ink batches
• Digital Process Visibility: variable frequency drive with chamber temperature and run-hour display lets operators record the exact milling profile used for each validated formulation

The WMS30 agitator bead mill fits inkjet ink plants, pigment concentrate producers, battery material developers and pharmaceutical suspension formulators across Germany, Poland, the Netherlands, Italy and Turkey. It is used for milling carbon black and organic pigments for inkjet and gravure inks, for dispersing conductive carbon and cathode or anode material in solvent and aqueous slurry, and for fine grinding of agrochemical and pharmaceutical suspensions where a narrow particle size distribution controls both stability and bioavailability. Because European customers frequently need documented cleanliness, the chamber can be supplied with a ceramic lining and the piping arranged for solvent flush and drain, so a validated cleaning procedure can be written around the agitator bead mill and audited during customer or notified-body visits.

Each WMS30 is assembled in an ISO 9001:2015 certified workshop and run for 72 hours with a reference pigment paste before dispatch; the particle size distribution curve, temperature log and seal leak record are issued with the machine. Critical parts are dimensionally inspected against a drawing-based checklist and shafts are dynamically balanced to G6.3. Documentation includes an IEC-style electrical schematic, P&ID for the cooling circuit, operation and maintenance manual, spare-part list and, where required, material and surface finish certificates to support customer qualification. CE-compliant guarded electricals with an emergency stop circuit are available for European delivery. The 12-month machine warranty excludes media and wear parts, spare parts are held for ten years, and remote commissioning with video verification of the first validated batch is included.
