Automotive & Battery

Battery materials have a purity specification, and that specification is where ceramic wear parts earn their place. Milling cathode or anode material with steel media adds iron to the product — which in a battery is a defect, not a wear cost. The same logic applies to pigments, coatings and any powder where a metal contamination limit is written into the purchase specification.

How wear actually happens

• Electrode material milling. Iron contamination has to stay below ppm levels, which rules out steel media regardless of wear rate.
• Slurry preparation and transfer. Cathode slurries are abrasive and often viscous; pumping and lines wear quickly at bends and in valves.
• Coating and drying equipment. Abrasive slurry through narrow passages, in equipment where a shutdown stops the whole line.
• Pigment and coating milling. Colour purity plus abrasion — the same contamination argument, a different industry.
• Powder handling and dosing. Fine abrasive powders worn through chutes, cyclones and small precision parts.

What we normally supply

• AL-99 / 99.7 grinding media, Ø0.5–20 mm, for bead and attritor mills
• AL-99 ceramic-lined pipe, elbows and fittings for slurry transfer
• AL-99.7 precision parts for pumps, valves and dosing equipment
• Porous ceramic elements for slurry filtration and gas distribution
• Alumina tiles and wear plates for hoppers and chutes
• Contamination statements with ppm-level iron pickup data

Typical grade and thickness

Starting points, not rules. The right specification depends on particle size, velocity and impact angle — send us the application and we will size it properly.
