Rubber-Backed Ceramic Tiles: Ultimate Protection Against Extreme Wear & Impact

Rubber-backed ceramic tiles combine the ultra-hard wear resistance of ceramics with the flexibility and impact absorption of rubber, offering a dual-layer protective solution for industrial applications. These tiles are engineered to withstand severe abrasion, heavy impact, and high-velocity material flow, making them a preferred choice in the mining, cement, steel, power, and bulk material handling industries.

Key Applications:
  1. Mining & Mineral Processing:
  • Transfer Chutes: Installed on chute surfaces to handle falling ore and rock at high speeds, reducing liner wear and structural fatigue.
  • Cyclone Spigots & Launders: Resist abrasive slurry flow and reduce maintenance downtime.
  • Feeder Linings & Mill Feed Chutes: Provide long-lasting wear resistance in high-impact zones.
  1. Bulk Material Handling Systems:
  • Bins, Hoppers & Silos: Minimize wear due to material build-up and impact from bulk solids.
  • Bucket Elevators & Discharge Points: Ensure continuous flow and reduce steel damage.
  • Loading & Unloading Zones: Protect against heavy drop impacts and eliminate liner breakage.
  1. Cement & Steel Industries:
  • Clinker Handling & Dust Extraction Systems: Ceramic tiles resist hot, abrasive particles.
  • Furnace Discharge Areas: Ideal for high-temperature, high-impact zones.
Construction and Composition:

Rubber-backed ceramic liners are typically composed of:

  • Front Layer – Ceramic Tiles:
    • Made from 92–95% alumina (Al₂O₃) for high hardness and superior abrasion resistance.
    • Arranged in square, hexagonal, or custom tile formations to maximize coverage and reduce wear spots.
  • Back Layer – Rubber Base:
    • Natural or synthetic rubber with excellent shock absorption properties.
    • Acts as a cushion to absorb impact forces and prevent cracking or delamination of ceramic tiles.
  • Bonding Layer (Optional):
    • May include a steel or fabric layer embedded within the rubber for added structural support and easier bolting or adhesion.
Manufacturing Process:
  1. Ceramic Tile Fabrication:
  • High-purity alumina powder is mixed with binders and shaped into tiles via pressing or casting.
  • Tiles are sintered at temperatures over 1,500°C to achieve hardness greater than 9 on the Mohs scale.
  1. Rubber Backing Preparation:
  • Rubber sheets are prepared with specific thickness and embedded with reinforcement layers if required.
  • Adhesive bonding agents are applied to promote adhesion between ceramic and rubber layers.
  1. Assembly and Curing:
  • Tiles are pressed into the uncured rubber or vulcanized together in molds.
  • The composite is cured under heat and pressure to ensure a secure bond.
  1. Finishing:
  • The final product is cut or molded to size.
  • Pre-engineered bolt holes or CN bonding layers may be added for field installation.
Installation Methods:
  • Bolt-On Liners: Pre-engineered liners with embedded steel plates or studs for mechanical fastening.
  • Cold Bonding: Using industrial adhesives and primers for on-site installation without heat.
  • CN Layer Bonding: A chemically treated layer that enhances rubber-to-metal adhesion when cold bonding.
Advantages of Rubber-Backed Ceramic Tiles:

Extreme Wear Resistance – Ceramic surface resists abrasion far better than steel or rubber alone.
Impact Absorption – Rubber backing absorbs shock loads, protecting both the tiles and substrate.
Reduced Noise & Vibration – Rubber dampens sound and equipment vibration.
Extended Equipment Life – Minimizes downtime and maintenance costs.
Customizable Designs – Available in panels, mats, or modular systems to fit curved or irregular surfaces.
Easy Installation – Lightweight, prefabricated panels simplify mounting and replacement.

Rubber-backed ceramic tiles offer a high-performance solution where abrasion, impact, and flow efficiency are critical. Their dual-layer design makes them ideal for demanding applications where conventional liners fail. From transfer chutes to cyclone spigots, these liners provide a reliable, long-term defense for your most vulnerable equipment.
