Industries We Serve: Advanced Wet Grinding & Nano-Dispersion Solutions Across Global Sectors
Cross-Sector Precision: Modern advanced material industries require tight particle size distribution (D50<100–300 nmD_{50} < 100\text{–}300\text{ nm}D50<100–300 nm) without coarse particle tails (D99D_{99}D99) that cause pinholes, nozzle blockages, or electrical shorts.
Zero Metallic Contamination: From EV battery cathode/anode slurries to dielectric ceramics, trace metal contamination (Fe, Cr, Ni<2–3 ppm\text{Fe, Cr, Ni} < 2\text{–}3\text{ ppm}Fe, Cr, Ni<2–3 ppm) is non-negotiable; Sanxing replaces metal wetted paths with solid sintered Silicon Carbide (SiC\text{SiC}SiC) and Zirconia (ZrO2\text{ZrO}_2ZrO2) ceramics.
Seal-Free Reliability: Submerged mechanical seals in conventional horizontal mills leak barrier cooling fluids and degrade under abrasive contact; Sanxing’s top-driven seal-free vertical architecture eliminates mechanical contact seals and barrier fluid contamination entirely across all served industries.
Micro-Media Fluidization: Incorporating dynamic centrifugal separation rotors allows high-flow multi-pass recirculation of 0.05–0.3 mm0.05\text{–}0.3\text{ mm}0.05–0.3 mm micro-media without static screen blinding.
Turnkey Engineering Scope: Beyond standalone bead mills, Sanxing delivers integrated EPC production systems—combining dust-free vacuum powder induction, sanitary premixing tanks, and digital PLC supervisory automation.
1. New Energy & Battery Materials
The ongoing transition toward high-energy-density and fast-charging energy storage demands uniform nanoscale control across both cathode and anode slurries:
Cathode Slurries (LFP / LMFP): Inherently low electronic conductivity requires reducing primary particle sizes down to D50=200–350 nmD_{50} = 200\text{–}350\text{ nm}D50=200–350 nm to shorten lithium-ion diffusion path lengths. Sanxing’s solid SiC\text{SiC}SiC ceramic chambers prevent foreign metallic iron and chromium leaching (<2 ppm<2\text{ ppm}<2 ppm), avoiding dendrite-induced separator punctures.
Silicon-Carbon & Hard Carbon Anodes: Controlled grinding prevents the excessive creation of ultra-fine dust, which balloons specific surface area (SSA) and reduces initial coulombic efficiency (ICE).
Solid-State Battery Electrolytes: Sulfide argyrodites (Li6PS5Cl\text{Li}_6\text{PS}_5\text{Cl}Li6PS5Cl) and garnet oxides (LLZO\text{LLZO}LLZO) require moisture-free, hermetic processing. Our seal-free vertical bead mills integrate with closed-loop argon/nitrogen atmospheres, enabling sub-300nm dispersion without hydrogen sulfide (H2S\text{H}_2\text{S}H2S) release.
2. Advanced Technical & Electronic Ceramics
In electronic and functional ceramics, component miniaturization mandates defect-free particle consolidation:
MLCC Dielectrics (BaTiO3\text{BaTiO}_3BaTiO3): Multi-layer ceramic capacitors require dielectric sheets below 1 μm1\ \mu\text{m}1 μm thickness. Agglomerates larger than 200 nm200\text{ nm}200 nm trigger localized electrical breakdown. Sanxing’s vertical mills deliver gentle, high-density hydrodynamic shear using 0.05–0.1 mm0.05\text{–}0.1\text{ mm}0.05–0.1 mm YSZ beads, achieving sub-100nm deagglomeration without destroying the crystalline tetragonality required for high dielectric permittivity.
Structural Ceramics (SiC,ZrO2,Al2O3\text{SiC}, \text{ZrO}_2, \text{Al}_2\text{O}_3SiC,ZrO2,Al2O3): Sintering high-hardness ceramic structural parts without residual micro-voids requires narrow grain distribution. Our ceramic-lined chambers eliminate cross-material contamination, maximizing green-body density.
3. Semiconductor & Electronic Chemicals (CMP Slurries)
Chemical Mechanical Planarization (CMP) dictates semiconductor device yield across advanced sub-10nm fabrication nodes:
The Killer Scratch Threshold: A single abrasive agglomerate exceeding 0.5 μm0.5\ \mu\text{m}0.5 μm creates micro-scratches across transistor gate oxide layers under downward pad pressure.
Sanxing Cleanroom Solution: We configure dedicated vertical bead mills with high-purity Silicon Carbide liners and dynamic centrifugal separation of 0.05 mm0.05\text{ mm}0.05 mm micro-media. The system gently breaks clustered ceria and silica aggregates down to D50≈60 nmD_{50} \approx 60\text{ nm}D50≈60 nm while maintaining D99.9<150 nmD_{99.9} < 150\text{ nm}D99.9<150 nm—completely cutting off the coarse Large Particle Count (LPC) tail.
4. Digital Printing Inks & High-Performance Coatings
Industrial drop-on-demand (DOD) printing requires stable, sub-micron colloidal fluids:
Digital Inkjet Inks (Ceramic, UV-Curable, Textile): Piezoelectric printhead orifices (10–20 μm10\text{–}20\ \mu\text{m}10–20 μm) clog immediately if coarse particles exceed 200–300 nm200\text{–}300\text{ nm}200–300 nm. Our vertical seal-free mills eliminate static discharge screens, allowing 0.05–0.1 mm0.05\text{–}0.1\text{ mm}0.05–0.1 mm beads to run at high recirculation rates to yield narrow particle envelopes (D99<150 nmD_{99} < 150\text{ nm}D99<150 nm) with zero nozzle dropouts.
Automotive & Transparent Coatings: Over-milling fractures primary organic pigment lattices, causing dull haze and re-agglomeration. Sanxing pin-rotor systems provide soft shear fields, maximizing optical transparency, chroma, and gloss.
5. Carbon Nanomaterials & Conductive Pastes
Conductive pastes require preserving particle morphology rather than crushing it:
Carbon Nanotubes (SWCNTs / MWCNTs): High-aspect-ratio (L/D>1,000L/D > 1,000L/D>1,000) nanotubes establish electrical percolation networks in battery electrodes at low loadings (0.1 wt%0.1\text{ wt}\%0.1 wt%). Brute-force milling fractures tubes into inactive soot. Sanxing vertical bead mills employ viscous micro-media shear to peel entangled bundles apart without shortening longitudinal tube length.
Graphene Exfoliation: Multi-pass liquid-phase shear in a seal-free vertical chamber cleanly exfoliates graphite into few-layer graphene nanosheets with high lateral dimension retention.
6. Agrochemicals & Crop Protection (SC Formulations)
Modern sustainable crop protection relies heavily on water-based Suspension Concentrates (SC):
Preventing Ostwald Ripening: By narrowing particle size distributions (D50=1.2–2.2 μm,D98<4.5 μmD_{50} = 1.2\text{–}2.2\ \mu\text{m}, D_{98} < 4.5\ \mu\text{m}D50=1.2–2.2 μm,D98<4.5 μm), Sanxing bead mills eliminate the chemical potential gradient that causes crystal growth and container sedimentation over 2-year storage periods.
Low-Melting Active Ingredients: Thermal-sensitive fungicides and insecticides (e.g., Pyraclostrobin, Tebuconazole) melt and jam conventional mills. Multi-zone spiral-baffled cooling jackets remove heat instantly, maintaining slurry temperatures safely below 28–30∘C28\text{–}30^\circ\text{C}28–30∘C.
