High Density Inert Alumina Ball for Catalyst Bed Support, Drying & Grinding

Inert Alumina Balls Applications

• Energy & Petrochemical Industry: Petrochemical Reactors & Catalyst Support

  ✅Key Advantages

  1. Stable guard/support layers — consistent sphericity reduces hotspots and channeling.
  2. High crushing strength — resists bed compaction during start-ups and thermal swings.
  3. Low leachables — protects hydrotreating/hydrocracking catalysts from trace contaminants.

  ✅ Problem Solved

  A hydrotreater revamped its support layer with high density inert alumina ball Ø19–25 mm and recorded ~7–10% lower initial ΔP, with stable ΔP after regeneration cycles and no fines carryover over the first campaign. Catalyst change-out time dropped because size-coded layers simplified loading.

• Oil & Gas Processing Industry: Natural Gas Drying / PSA–VPSA

  ✅Key Advantages

  1. Inert packing under molecular sieve or activated alumina — improves flow distribution.
  2. Polished surface option — facilitates fast loading and unload, less dust entrainment.
  3. Thermal durability — tolerates regeneration temperatures typical to dryers.

  ✅ Problem Solved

  A gas dehydration unit using 4 mm sieve added inert alumina ceramic balls as a graded support. The bed showed more uniform temperature fronts and extended cycle length, reducing operational interruptions and improving dryer efficiency.

• Environmental Industry: Water Treatment & Adsorbent Protection

  ✅Key Advantages

  1. Inert separation layers — prevent adsorbent migration in defluoridation and dearsenication beds.
  2. Chemical stability — withstands long-term exposure to varying water chemistries without leaching.
  3. Low attrition rate — ensures minimal dust contamination in potable water treatment units.

  ✅ Problem Solved

  A municipal water treatment facility installed customized alumina ceramic inert packing balls beneath activated alumina adsorbents. The upgrade reduced adsorbent carryover incidents by 15%, while maintaining stable ΔP and lowering replacement frequency, directly cutting annual maintenance costs.

Inert Alumina Ball Usage Instructions

• Installation

  1. Verify vessel is clean and dry; check screens/support grids for damage.
  2. Load the largest size at the bottom transitioning to smaller sizes; maintain the specified bed height and layering diagram.
  3. Record bulk density, bag counts, and lot IDs for traceability.

• Operation

  1. Ramp temperatures and pressure gradually at start-up to limit thermal shock.
  2. Monitor ΔP across bed; rising ΔP may indicate fines contamination or mal-distribution.
  3. For dryers, follow the specified regeneration temperature/time to avoid binder degradation in the adsorbents layered above.

• Storage

  1. Keep sealed in dry area; avoid contact with acids/alkalis during storage.
  2. Use pallets; prevent bag puncture and water ingress.

• Cleaning / Change-out

  1. Vacuum or screen recovered balls; discard cracked or out-of-round pieces.
  2. For mills, periodically sieve media charge and top up with the same size curve to maintain grinding efficiency.

• Common Misuse & Remedies

  1. Problem: Unexpected ΔP rise soon after start-up.
  Check: size layering sequence, fines from upstream, or collapsed screens.

  2. Problem: Catalyst contamination alerts.
  Check: verify alumina purity spec and leachable limits; request lot analysis.

  3. Problem: High mill contamination.
  Check: switch to higher-purity or high-density grade; verify slurry pH and solids loading.

Inert Alumina Balls FAQ

1. Q: What sizes are standard for inert alumina ceramic balls?
   A: Common support sizes are 3, 6, 10, 13, 19, 25, 38, and 50 mm; grinding media can be 0.5–30 mm. Custom diameters with tighter tolerance are available.
2. Q: What is the difference between a standard and high density inert alumina ball?
   A: A high density inert alumina ball offers stronger crushing strength and lower wear rate, making it suitable for reactors with high pressure drop or long operating cycles. Standard density balls are more cost-effective for general packing and distribution layers.
3. Q: How can I get inert alumina balls price or a quotation?
   A: You can request inert alumina ceramic ball quotes by providing size, purity, density grade, and order volume. Our sales team will quickly prepare an inert alumina ball quotation based on your technical requirements.
4. Q: Do you provide wholesale inert alumina ceramic balls?
   A: Yes, we support wholesale inert alumina ceramic ball supply in bulk packaging such as 25 kg bags and 1,000 kg jumbo bags. Wholesale orders help reduce per-ton cost and ensure stable inventory for continuous operation.
5. Q: Can inert alumina ceramic balls be used as catalyst support?
   A9: Absolutely. Inert alumina ceramic balls as catalyst support are widely used in hydrotreating, reforming, and cracking units. They prevent catalyst fines from migrating, improve flow distribution, and extend catalyst bed life.
6. Q: Are you a factory?
   A:Yes, ADCERAX, a China inert alumina ball factory with 20+ years of engineering know-how. We manufacture inert alumina ceramic balls in both standard and customized grades, including high density and high purity options. As a direct manufacturer, we supply bulk and wholesale inert alumina balls for catalyst support, drying units, and grinding applications, providing high quality product performance and on-time supply..
