In the high-stakes world of specialty paper manufacturing—thermal paper, carbonless copy paper, barrier coatings, and water transfer printing films—particle size is everything. The secret behind premium coating performance? Advanced wet grinding technology.

The WM Series Advantage

Our WM Horizontal Closed Sand Mills deliver the precision your coating chemicals demand:

✅ Ultra-Fine Dispersion – Achieve ≤20μm particle size with narrow distribution, critical for microcapsule-based thermal coatings and uniform barrier layers

✅ Explosion-Proof Design – Exd Ⅱ BT4 rated for safe handling of solvent-based coating formulations and volatile chemical systems

✅ Continuous Processing – From 20kg/h pilot scale to 2000kg/h production, maintaining consistent quality batch after batch

✅ Smart Temperature Control – Spiral cooling jackets keep your heat-sensitive dispersions stable, preventing premature reactions in thermal or carbonless chemistries

Real Applications, Real Results

 Thermal Paper Coatings – Precise grinding of leuco dye developers and sensitizer dispersions for crisp, reliable image formation

 Water Transfer Printing – Uniform pigment dispersion ensuring flawless pattern transfer on complex 3D surfaces

 Barrier Coatings – Nano-level particle size for superior moisture/grease resistance without plastic lamination

 Carbonless Paper – Perfect microcapsule size distribution for consistent color development pressure

Built for Modern Compliance

With Europe's PPWR (Packaging and Packaging Waste Regulation) driving demand for recyclable, plastic-free barrier coatings, your grinding equipment must handle next-gen water-based and bio-based formulations. Our sand mills are engineered for exactly this evolution—processing high-viscosity, multi-component systems with zero contamination risk.

Ready to Upgrade Your Coating Line?

Don't let outdated grinding limit your product innovation. Whether you're developing phenol-free thermal coatings or high-gloss inkjet receiver layers, the right dispersion equipment makes the difference between commodity and specialty-grade output.
