High-density ceramic grinding balls and beads for wet and dry milling of battery cathode materials, pigments, coatings, and mineral slurries. Zero metal contamination — critical for battery and electronics applications.
Si₃N₄ for the hardest materials and highest purity; ZrO₂ for general-purpose high-energy milling of battery and pigment slurries.
Silicon nitride grinding balls for hard mineral milling and ultra-high-purity applications. Hardness 78 HRC — outlasts zirconia media 3–5× in abrasive slurries.
Zirconia grinding balls for battery cathode/anode slurry milling, pigment dispersion, and mineral processing. High density (6.0 g/cm³) delivers excellent milling energy.
Metal contamination ruins battery electrode performance. Ceramic media eliminates the risk.
Steel media contaminate battery slurries with Fe ions that degrade cathode performance. Ceramic media contributes zero metal ions.
Si₃N₄ outlasts alumina 3–5× and steel 10–20× in hard abrasive slurries — lower total cost of ownership.
ZrO₂ density 6.0 g/cm³ vs alumina 3.9 g/cm³ — more impact energy per ball, reducing milling time.
Uniform sphericity and low size variance give reproducible D50 — critical for battery electrode control.
LFP/NMC cathode slurry, lithium carbonate, pigment dispersions, TiO₂, and mineral concentrates.
0.4mm to 100mm across both materials. Stock sizes dispatch within 48 hours.
Battery materials, pigments, coatings, minerals — any slurry where contamination, purity, or wear life is critical.
NMC/LFP cathode slurry, lithium carbonate, and solid-state electrolyte powder milling. Zero Fe contamination critical.
TiO₂, carbon black, and organic pigment dispersions for paints, inks, and coatings.
Hard mineral concentration and ceramic powder milling — silica, alumina, and advanced ceramic feedstocks.
Particle size reduction for drug formulation and food ingredient processing.
Milling of ceramic precursor powders for sintering — Si₃N₄, SiC, AlN, ZrO₂ feedstock.
Catalyst milling, chemical reaction intermediates, and specialty dispersion applications.
One of our longest-running OEM partners — switched from a European competitor's alumina igniters to our BLK series Si₃N₄ in 2018. Warranty returns dropped 38% in the first 12 months; cold-start failures (sub-zero installs) dropped 32%. Now in year 7 of supply.
