Custom Alumina Lining Board for Ball Mills, Kilns & Cyclones | High Wear & Thermal Resistance

Alumina Lining Board Applications

• Mining & Quarry — Chute/Hopper Transfer Points

  ✅Key Advantages

  1 — Impact-zone longevity: Hex mosaic at the drop zone cuts localized wear rate, extending reline intervals by ~2× in high-energy impact.
  2 — Mixed pattern economy: Combining mosaic and large tiles reduces liner cost per tonne without sacrificing uptime.
  3 — Predictable maintenance: Stable wear profile enables scheduled swaps during planned outages.

  ✅ Problem Solved

  A gold-ore chute experienced unscheduled shutdowns every 4–6 weeks due to rapid wear at the impact toe. Switching to a mixed layout (20 mm hex mosaic at impact; 15 mm large tiles downstream) extended service intervals to 10–12 weeks and cut emergency stoppages by ~35%. Annual lost-time costs fell by a mid-five-figure amount, while liner spend stayed within budget.

• Cement Plant — Separator/Duct & Cyclone Inlet

  ✅Key Advantages1 — Smooth internal flow: Tight joint control (<2 mm grout lines) reduces eddies that accelerate powder erosion.
  2 — Temperature-ready: Consistent plate thickness and backing selection suit preheater/duct sections with steady thermal loads.
  3 — Fast alignment: ID marking and panel maps shorten fit-up time during short shutdowns.

  ✅ Problem Solved

  A kiln preheater duct with uneven grout lines created dust eddies and hot-spot wear. Precision-cut plates with chamfered edges and 1–2 mm spacers improved flow uniformity; liner life moved from 6–8 to 14–16 months. Planned outage duration remained unchanged, but unplanned inspections dropped significantly.

• Power & Coal Handling — Transfer Points/Elbows

  ✅Key Advantages1 — Steel-back modules: Weld-on assemblies allow rapid exchange in tight windows.
  2 — Rubber-ceramic damping: Composite plates mitigate particle impact ringing and reduce adhesive dependence in oily environments.
  3 — Traceable batches: Lot code + plate ID pairing simplifies QA root-cause checks.

  ✅ Problem Solved

  A power station’s transfer elbow suffered premature wear and adhesive failure due to surface oil. Converting to rubber-ceramic bolt-on plates stabilized service life at 12–15 months and eliminated bond-line failures; the station aligned liner swaps with quarterly inspections.

Alumina Lining Board Usage Instructions

• Installation

  1. Substrate prep: Remove old liners and residue; grind to a uniform profile; degrease; achieve 60–80-grit surface.
  2. Dry fit & mapping: Lay out plates per panel map; confirm joint gaps (target 1–2 mm).
  3. Adhesive bonding: Mix two-part adhesive; apply 1–2 mm wet bond line; press plates from the reference edge; use spacers; clean squeeze-out.
  4. Cure & check: Hold at 20–25 °C to full cure; tap-test and visually inspect joints; remove spacers and grout if required.
  5. Alternative fixings: For high-impact or oily areas, use rubber-ceramic bolt-on or steel-back welded modules.

• Storage

  1. Keep boxed plates flat, dry, and off the ground; avoid stacking that applies direct pressure on edges or corners.
  2. Maintain a stable environment of 5–30 °C with low humidity to prevent adhesive degradation and surface moisture.
  3. Store steel-backed or rubber-backed modules separately with protective sheets to avoid corrosion or compression marks.
  4. For long-term storage, apply protective film or shrink wrap around crates to keep out dust and prevent accidental chipping.

• Cleaning & Inspection

  1. During planned outages, vacuum or blow off accumulated dust to keep surfaces free of debris that may accelerate joint wear.
  2. Inspect joint lines, impact zones, and grout edges for cracks, lifted corners, or gaps larger than 2 mm.
  3. Replace isolated damaged or missing tiles immediately to prevent undercutting and progressive failure of adjacent plates.
  4. Check for discoloration or adhesive bond weakness as signs of overheating or chemical exposure.
  5. Document wear patterns with photos or thickness measurements to build a maintenance record for predicting replacement cycles.

• Common Misuse & Remedies

  1. Issue: Adhesive failure on oily steel → Remedy: Switch to rubber-ceramic bolt-on or sandblast to white metal + solvent wipe before bonding.
  2. Issue: Gaps >3 mm create eddies → Remedy: Re-cut edge tiles; maintain 1–2 mm joints with spacers.
  3. Issue: Random wear spots at impact → Remedy: Upgrade to a hex mosaic or a thicker plate just in the impact footprint.

Alumina Ceramic Lining Plate FAQ

1. Q: Is your lining board suitable for ball mill use?
   A: Yes, we supply alumina liner plates that are tested for both batch-type and continuous ball mills.
2. Q: Are drilling or complex contours possible?
   A: We support CAD-based hole positioning, profiling, and special shapes.
3. Q: How long will the liner last under abrasive use?
   A: Service life varies, but generally 6–12 months, depending on operating intensity.
4. Q: What thickness should I choose for alumina lining plate?
   A: Most transfer points use 15–25 mm; impact toes may use 20–40 mm or mosaic. Choose thickness by particle size, drop height, and belt speed.
5. Q: How do I select a fixing method (adhesive, rubber-ceramic, steel-back)?
   A: Use adhesive for clean, stable ducts; rubber-ceramic bolt-on for oily or high-impact zones; steel-back weld-on for fastest swaps and heavy duty.
6. Q: What is the typical service life versus rubber or PU?
   A: In comparable duty, alumina lining plate commonly achieves ~1.8–2.4× longer intervals; exact results depend on ore, velocity, and impact energy.
7. Q: Do you supply steel-backed or rubber-ceramic composite liners?
   A: Yes. Both are available for bolt-on or weld-on installations where adhesive is not preferred.
8. Q: What information is required for a alumina lining plate quotation?
   A: Provide drawings or dimensions, thickness, pattern (mosaic/plate), fixing method, quantity by zone, and any curvature data.
9. Q: When should alumina lining plate replacement be carried out?
   A: Replacement is usually required when joint gaps exceed 2–3 mm, tiles show cracks or lifted corners, or the impact zone wears down by more than 30% of its original thickness. Timely alumina lining plate replacement prevents undercutting of adjacent panels and avoids unexpected downtime.
