Repair Composites for the Mining Industry
Cold-applied composites for in-situ, weld-free repairs
Belzona delivers fast, cold-applied repair solutions that keep mines running by tackling abrasion, corrosion, impact, and chemical attack across critical assets.
From rebuilding worn mills, pumps, chutes, and conveyor belts to lining pipes, tanks, and thickeners, Belzona composites and coatings restore dimensions, resist wear, and protect against harsh slurries and chemicals. Rapid-cure elastomers and high-strength polymer systems enable in-situ, weld-free fixes that minimize downtime and extend service life. The result is safer, longer-lasting equipment performance and lower total maintenance costs across the entire mining operation.
Safer, longer-lasting equipment performance and lower total maintenance costs across your entire mining operation.
Metal Equipment & Process Vessels
- Grinding mill repair & protection – Rebuild/line liners, trunnions, trommel screens and shells to resist abrasion and impact.
- Hydrocyclones – Rebuild/line cyclone cones with high-molecular-weight, ceramic-filled systems for aggressive slurry service.
- Slurry pump linings – Rebuild casings/impellers and line wetted parts to resist severe erosion-corrosion.
- Filter press plate restoration – Restore worn plate edges to original dimensions and sealing performance.
- Flotation cells – Fill wall voids and apply erosion-corrosion-resistant linings to steel tanks.
- Engine block repairs – Seal cracked blocks without heat to avoid distortion/brittle welds.
- Shaft rebuilding (in-situ) – Restore worn journals/diameters without stripping or welding.
- Oversized keyways – Form precise, zero-tolerance fits with epoxy composites using the new key as a former.
- Bearing housing restoration – Rebuild distorted/oversized housings to correct fits and return machinery to service.
- Crusher bowl liner repairs – Secure and rebuild worn components in-situ to reduce vibration and extend liner life.
Concrete, Masonry & Building Substrates
- Roofing membranes – Liquid-applied, flexible waterproofing for long-term roof repairs (including emergency wet-surface applications).
- Wall maintenance – Repair joints/damage and coat walls to stop leaks and ingress.
- Floor repair & protection – Rebuild and coat concrete/stone floors for impact, abrasion and chemical resistance.
- Concrete base repair – Use fast-curing magma polymers to repair/resurface bases and plinths with excellent bond strength.
- Shimming, backing & leveling (chocking) – Precisely align/stabilize heavy equipment with non-shrinking, high-strength compounds.
- Containment areas (bunds, sumps) – Brush/spray-applied chemical barrier linings protect concrete from spills and immersion.
- SX/EW tankhouse floors/walls – Chemical-resistant magma polymer linings shield concrete from aggressive acids/alkalis.
Rubber & Elastomer Components
- Conveyor belt repair – Patch rips, tears and holes with abrasion-resistant elastomers for durable, fast returns to service.
- Drive roller grip restoration – Apply high-adhesion grip systems to eliminate belt slippage without dismantling.
- Heavy-duty tyres – Cold-cure elastomers seal sidewall splits/holes to halt propagation and extend tyre life.

Protective Coatings and Linings for the Mining Industry
Belzona coatings and linings specifically formulated to protect equipment in the mining industry
Abrasion – Protect your mining equipment and structures from severe abrasive wear with Belzona.
- Grinding mills (liners, trunnions, trommel, shells) – Ceramic/polymer systems protect high-wear zones from friction and impact during grinding.
- Material transfer systems (hoppers, chutes, channels, feeders) – Alumina-tile/epoxy linings shield flow surfaces from rapid erosion to cut downtime.
- Pipes & ducts (elbows, tees) – Seamless ceramic polymer linings resist abrasion from fine/coarse particles and elevated temperatures.
- Hydrocyclones – High-molecular-weight, ceramic-filled composites withstand severe slurry abrasion in cyclone cones.
- Screw conveyors – Abrasion-resistant systems protect flights, shafts and troughs to extend service life.
- Slurry pump wetted parts – Elastomers and ceramic composites combat erosion on casings and impellers.
Corrosion – Protective coatings providing superior corrosion protection in harsh operating and environmental conditions.
- Flotation cells – Void-filling repairs plus erosion-corrosion-resistant coatings create a seamless lining and mitigate galvanic corrosion once wear exposes steel.
- General wet process assets – Durable coatings provide corrosion, erosion and cavitation protection in moisture-rich mining environments.
- Slurry pumps – Protective linings address both abrasion and corrosion from aggressive slurries.
Chemical attack – Protective coatings providing outstanding chemical resistance against a wide variety of harsh chemicals.
- SX/EW tankhouses – Chemical-resistant magma polymer linings protect walls and floors in highly acidic/alkaline environments.
- Thickeners (tanks & rakes) – Immersion barrier coatings defend against flocculants/coagulants and solids-laden slurries.
- Containment areas (bunds, sumps) – Brush/spray-applied chemical linings prevent spillage-induced deterioration and pollution risk.
- Process areas under strong chemical exposure – Epoxy repair composites/coatings provide resistance up to 98% sulfuric acid and a wide range of chemicals.
NanoPrep – Rust Primer & Anticorrosive Industrial Coating
NanoPrep’s surface preparation technology allows industrial coating application in areas where it is difficult, cost prohibitive or impossible to perform surface preparation by abrasive grit blasting.
NanoPrep is a one component, waterborne, acrylic co-polymer composition that reacts and cross-links with rusted steel surfaces, clean steel, painted steel, aluminium, and/or galvanised steel surfaces creating superior anticorrosive properties.
