The mining and quarrying industry plays a vital role in the global economy, supplying raw materials for construction, metallurgy, energy, and many other sectors. However, operating in harsh conditions – dust, moisture, heavy impact, and abrasive materials – causes equipment and structures to deteriorate quickly.
Common problems such as conveyor belt tears, shaft wear, cracked hoppers, reduced pump efficiency, or misaligned foundations can result in:
- Production downtime
- High repair and replacement costs
- Safety risks for workers and machinery
In this context, Belzona provides a range of rapid, durable, and cost-effective repair and protection solutions for the mining industry.
1. Conveyor Belt and Rubber Component Repair
Challenges
- Conveyor belts are the main transport system, constantly exposed to heavy loads and sharp impact from rocks and ores.
- Rubber components on belts and tires tear, abrade, and degrade quickly.
Full replacement is costly and leads to prolonged downtime.
Solution
- Belzona 2111 (D&A Hi-Build Elastomer): a cold-applied polyurethane elastomer designed for bonding, patching, and rebuilding rubber.
- Can be applied in-situ, without heat or special equipment.
- Properties: high elasticity, tear resistance, excellent adhesion to rubber, steel, and fabric.
Benefits
- Quick repair, minimizing downtime.
- Extends service life of belts and rubber accessories.
- Reduces replacement costs and risk of further breakdowns.
2. In-Situ Shaft Repair
Challenges
- Shafts are subject to wear and corrosion at seal and bearing areas.
- This results in vibration, misalignment, and lubricant leakage, which can cause unexpected shutdowns.
Solution
- Belzona 1111 (Super Metal): a two-part epoxy composite reinforced with steel, restoring damaged shaft surfaces with precision.
- No welding required, eliminating thermal distortion.
- Can be applied directly on site.
Benefits
- Reduces downtime.
- Restores shaft geometry accurately.
- More cost-effective than shaft replacement.
3. Protection for Hoppers, Chutes, and Pipes
Challenges
- Material handling systems suffer constant abrasion, impact, and cracking, leading to leakage and structural damage.
Solution
- Belzona 1812 (Ceramic Carbide) or Belzona 1321 (Ceramic S-Metal): ceramic-filled polymer coatings designed for extreme abrasion resistance.
- Easy to apply and suitable for in-situ lining of hoppers, chutes, and pipes.
Benefits
- Enhanced resistance to abrasion and impact.
- Maintains system reliability, reducing replacement of steel structures.
- Long-term maintenance cost savings.
4. Pump Repair and Protection
Challenges
- Mining pumps face severe erosion and corrosion from slurry, seawater, and chemicals.
Performance declines quickly, increasing energy consumption.
Solution
- Belzona 1341 (Supermetalglide): a hydrophobic epoxy coating with ultra-smooth surface, reducing flow resistance.
- Can be applied after pump body and impeller repairs with Belzona 1111 or Belzona 1311.
Benefits
- Improves hydraulic efficiency by up to 7% for new pumps and 20% for refurbished pumps.
- Extends pump lifespan and reduces energy costs.
- Provides long-term corrosion and erosion protection.
5. Machinery Shimming and Chocking
Challenges
- Heavy machinery often suffers from vibration and misalignment, leading to imbalance, wear, and structural damage.
Solution
- Belzona 7111 (Industrial Grade Pourable Epoxy Resin): a pourable epoxy for machinery foundation grouting, shimming, and chocking.
- Offers high compressive strength, chemical resistance, and vibration damping.
Benefits
- Ensures stable machinery operation.
- Minimizes repair costs caused by vibration.
- Increases safety and structural durability.
