We are a producer, not a reseller. Six lines in Zibo — the heart of China's alumina-chemicals belt — run calendar-coded batches, so every drum traces back to its firing run.
Tell us what you need to dry, purify or separate — we match the exact grade and pore size.
100 kg standard — small enough for a first trial, with container quantities priced from the same production line.
Send your current media's spec sheet or a used sample. Our engineers match crushing strength, hydration and particle-size curves before quoting.
FOB Qingdao as standard; CIF / DAP available to most ports. 25 kg bags, 1-ton jumbo bags or steel drums. 7–15 day lead time.
Drying-tower refill guidance, bed-depth calculations and troubleshooting from engineers who run the lines — average first reply 47 minutes.

Aluminaworld (okkinc.com) is a direct manufacturer of industrial adsorbents and catalysts based in Zibo, Shandong, China — the aluminium-chemical hub of China. The company operates its own six production lines and has shipped to buyers in 86+ countries for over 18 years, without trader markup.
The product portfolio covers five families: activated alumina (300–360 m²/g BET, 92–93% Al₂O₃, balls and powder) for compressed-air drying, transformer breathing, drinking-water defluoridation and catalyst support; molecular sieve (3A, 4A, 5A, 13X and powder grades) for air, natural gas and PSA oxygen/hydrogen drying; alumina powder (calcined and tabular alpha-alumina) for ceramics, coatings, polishing and refractories; aluminum hydroxide (ATH) as a flame retardant for LSZH cables and a filler for artificial marble; and catalyst carriers including activated alumina and pseudo-boehmite for Claus, H₂O₂ and FCC applications. ZSM-5 zeolite (SiO₂/Al₂O₃ molar ratio 25–1000) and pseudo-boehmite (CAS 125740-10-5) are produced on the same lines.
Typical specification ranges: molecular sieve 3A/4A bulk density 0.62–0.68 g/ml, water adsorption ≥21%, crush strength ≥45 N; 5A/13X bulk density 0.62–0.70 g/ml, water adsorption ≥21.5%; activated alumina ball bulk density 0.70–0.85 g/ml, attrition rate ≤0.4 wt%, water adsorption ≥50%. Standard particle sizes run 1–3 mm, 2–5 mm, 3–5 mm, 4–6 mm and 5–8 mm for balls, with 50–200 mesh powder grades.
