Wear-resistant Alumina Lining Brick for Ball Mills & Bulk Handling — Standard Sizes & Customization

Alumina Ceramic Lining Brick Applications

• Mining & Mineral Processing — Mill Cylinder Lining

  ✅Key Advantages

  1. Campaign Life Doubling — High-density alumina ceramic lining brick (95–99% Al₂O₃, ≥3.6 g/cm³) extends liner life 1.8–2.4× versus steel/rubber.
  2. Lower kWh per ton — Smooth ceramic interface cuts media friction, typically reducing grinding energy 5–12% at stable throughput.
  3. Precision Curved Kits — Arc-matched curved bricks keep joints ≤2.0 mm, reducing edge-chipping and misalignment alarms 30–40%.

  ✅ Problem Solved

  On a 2.4 m ball mill, a 40 mm alumina brick kit replaced mixed steel/rubber liners: average liner life rose from 9 to 18 months, annual shutdowns dropped 3 → 1, media consumption fell ~9%, and energy per ton by ~6%. The mill maintained a steadier d₈₀ and cut off-spec lots by ~20%, reaching payback in ~7 months based on avoided downtime and media savings.

• Ceramics & Pigments — Colour-Sensitive Grinding

  ✅Key Advantages

  1. Low Fe Pick-up — Inert alumina ceramic lining bricks help keep iron contamination <0.02% (or ↓60–80% vs steel), stabilizing glaze/pigment colour.
  2. Polished Flow Surface — Optional ground/polished finish (Ra ≤ 0.6 μm) lowers residue and cross-colour carryover 30–50%.
  3. Tight-Joint Layout — Trapezoid/curved bricks minimize grout lines, shortening CIP/clean-out time 25–35%.

  ✅ Problem Solved

  A pigment line switching to 95% alumina bricks saw slurry Fe drop from 110 ppm → 25 ppm, whiteness index improved by ~3 points, and colour rework reduced ~40%. Clean-outs fell from 6 to 3 per month, saving ~52 labor hours/month and improving first-pass yield by ~4–5%.

• Chemical Powder Handling — Chutes, Cyclones & Elbows

  ✅Key Advantages

  1. Build-up Control — Hard, low-roughness alumina surfaces reduce wall build-up at elbows/cyclones by 25–40%, keeping mass flow stable.
  2. Impact-Zoned Thickness — Brick sets with localized +10–20 mm at strike points cut spalling incidents ~60%.
  3. Bond Reliability — Adhesive-bonded tiles with verified bond shear ≥15 MPa maintain lining integrity under continuous duty.

  ✅ Problem Solved

  On a pneumatic conveying loop, lining chutes and a cyclone with 20–40 mm alumina bricks cut blockage events 8 → 3/quarter, increased average throughput ~6%, and reduced unscheduled maintenance by ~120 hours/quarter. OEE rose 4–6%, with lining costs recovered in ~5 months through avoided stoppages.

Alumina Lining Brick Usage Instructions

• Installation

  1. Dry-fit tiles per layout map; keep grout lines consistent (≤1.5–2.0 mm).
  2. Clean substrate; apply two-part ceramic adhesive evenly with a notched trowel.
  3. Press tiles from reference datum; use spacers; remove squeeze-out.
  4. Cure per adhesive sheet(typical 24 h at ambient); avoid impact during cure.

• Operation

  1. Ramp up with process media present; avoid dry running at full speed.
  2. Inspect feed/head zones first—replace cracked pieces early to protect the array.

• Cleaning & Inspection

  1. Use non-metallic tools; avoid local hammering.
  2. Record wear thickness at fixed points every shutdown to predict next changeout.

• Storage

  Keep cartons on pallets in a dry warehouse; avoid stacking beyond pallet rating; do not expose to rain or acidic vapours.

• Common Mis-operations & Fixes

  1. Uneven joints → re-level with shims; re-bond loose tiles immediately.
  2. Adhesive starvation → increase spread rate; verify open time vs ambient temperature.
  3. Wrong arc radius → request revised curved tiles; do not force-fit to avoid edge spalling.

Alumina Lining Brick FAQ

1. Q: Are these bricks suitable for induction furnaces?
   A: Alumina bricks are typically used for wall linings, not the crucible lining of induction furnaces, due to magnetic flux disturbance.
2. Q: How should I calculate my project quantity?
   A: Share your furnace/kiln internal dimensions or lining layout. We'll assist in computing the total brick count and cutting plan.
3. Q: Do these bricks require initial baking after installation?
   A: Yes. A controlled heating curve is required post-installation to avoid early crack development due to moisture.
4. Q: Does the material release any gas or contaminants under heat?
   A: No. Our raw material is free of volatile impurities, suitable even for clean-room grade heat chambers.
5. Q: Can I request alumina lining bricks quotes for mixed shapes?
   A: Yes—send mill shell ID/length, head drawings, and target Al₂O₃ grade; you’ll receive itemized quotes for rectangles, trapezoids, and curved tiles in one sheet.
6. Q: Are you an alumina lining brick supplier or a factory?
   A: ADCERAX operates as a China factory with engineering support; we also supply accessories to streamline installation.
7. Q: What grade should I choose—92%, 95%, or 99%?
   A: 92% suits general abrasion; 95% balances life and cost; 99% is for high-purity or colour-sensitive grinding.
8. Q: Can I bundle grinding media and lining together?
   A: Yes—many buyers procure alumina grinding balls and liners together to control media/liner interaction.
9. Q: Can I purchase alumina lining bricks directly from a manufacturer in China?
   A: Yes, ADCERAX is a China-based manufacturer of alumina lining bricks, supplying both standard tiles and custom kits. Buying factory-direct helps control cost while ensuring engineering support for drawings and tolerance.
