New energy and new materials

It depends mainly on the target particle size. For the finest ceramic slurries the screen-free vertical mills fit best: the LPM series is specified for 30–1000 nm with media down to 0.05 mm, and the vertical dual-power series for 50–2000 nm with media from 0.03 mm. For nano ceramics in the 100–1500 nm range, such as barium titanate, alumina and zirconia, the NCT turbine mill is the usual choice. Where the target is coarser, up to a D50 of 20 µm, or for structural and electronic ceramic slurries in larger volumes, the disc mill covers D50 100 nm to 20 µm. A test grind on your own powder confirms the choice.

Purity depends on what touches the slurry. The NCT turbine mill uses a ceramic grinding chamber for contamination-free grinding and higher material purity, and the dual-power mills offer chamber materials in silicon carbide, polyurethane, zirconia or high-purity alumina so the lining can be matched to the powder. On complete ceramic powder lines, wear-resistant materials are combined with multi-stage impurity removal. Choosing grinding media and a chamber lining compatible with the ceramic being ground is the first step.

Yes. The lab horizontal sand mill lists ceramic slurry among its applications and covers 100–1500 nm with 0.1–2.0 mm media. INFOR laboratory mills use the same grinding principles as the production series, so a recipe proven on a lab chamber can be transferred to an NCT or LPM production mill. INFOR also runs free material tests on customer samples before a mill is specified.

Yes. The ceramic material sand mill production line is a fully enclosed, continuous system for sub-micron to nano ceramic powder. Its process runs from metering and pre-mixing through multi-stage classification grinding, intelligent control and impurity removal to drying and powder making, with dry or wet processes as required. It is used for structural ceramic powders such as alumina, zirconia, silicon nitride and silicon carbide, electronic functional ceramics including MLCC, piezoelectric ceramics and bioceramics, and ceramic body and glaze materials.
