Explore factory-direct ceramic structures, ultra-fine micronization grinding beads, and random packing elements engineered to minimize pressure drop and operational wear.
Operating within Pingxiang—the epicenter of industrial ceramics since 2003—Zhongtai converges raw material synthesis, precision isostatic pressing, and advanced tunnel firing.
Our facility directly secures calcined alpha-alumina and microcrystalline zirconia powders within local supply corridors, ensuring tight control over grain boundary structures and eliminating contamination from free silica and heavy metals.
We deploy dual manufacturing modalities: automated multi-axis rolling for high-roundness micro-beads (<0.5mm to 6mm) and ultra-high-pressure cold isostatic pressing (CIP) for large-diameter balls (20mm to 70mm), achieving zero internal voids.
Sintering occurs across computer-monitored, 100-meter automated natural gas tunnel kilns firing up to 1680°C. Micro-zoned heat profiles ensure uniform phase transition into dense alpha-corundum crystal matrices with ultra-low wear rates.
Every metric is tested per production lot under strict international quality protocols (ISO 9001:2015, ASTM C373, and DIN EN ISO 8442).
| Media Classification | Composition Ratio | Bulk Density (g/cm³) | Mohs Hardness | Primary Industrial Use Cases |
|---|---|---|---|---|
| High-Alumina Grinding Beads | 92% Al₂O₃, Balance SiO₂/Fe₂O₃ | ≥ 3.60 | 9.0 | Ceramic body/glaze ball milling, zircon sand, calcium carbonate wet grinding. |
| Ultra-Wear Alumina 95% | 95% Al₂O₃, Micro-crystalline | ≥ 3.70 | 9.0 | Non-metallic minerals, white cement, battery cathode precursor dispersion. |
| Yttria-Stabilized Zirconia (YSZ) | 95% ZrO₂, 5.2% Y₂O₃ | ≥ 6.00 | 9.0 | Lithium iron phosphate (LiFePO4), nano-coatings, MLCC dielectric ceramics. |
| Inert Catalyst Bed Supports | 17%–99% Al₂O₃ Grades | 1.35 – 2.05 (Bulk) | 7.5 – 8.5 | Petroleum hydrocracking, ammonia synthesis, packed absorption columns. |
Addressing the shifting paradigm from high-emission batch processing to continuous, ultra-fine nano-grinding and low-carbon chemical distillation.
The global surge in EV battery cathode/anode production requires zero-iron nano-milling. Our micro-crystalline yttria-stabilized zirconia beads provide high shear forces down to sub-micron particle distributions (D50 < 100nm) without contaminating lithium slurry.
Modern packed columns demand structured corrugated packings and high-efficiency ceramic saddles to reduce steam reboiler duty. We provide full column internals and catalyst support beds that resist aggressive sour gas, reducing turnaround cycles by up to 35%.
For high-viscosity coatings and SC pesticides, media roundness and high sphericity (≥0.98) prevent chamber screening clogging. Our narrow bead size brackets optimize kinetic energy transfer while eliminating mechanical mill wear.
