Mining and Quarrying Industry – Repair Composites and Coatings

Belzona metal and rubber repair composites, coatings and linings are specifically formulated to repair and protect equipment in the mining and quarrying industry.

Belzona's wide range of polymeric metal and rubber repair composites and durable protective coatings and linings have been used in the mining industry for decades. These materials are specifically designed to provide outstanding erosion, corrosion and abrasion protection, as well as chemical resistance, for equipment operating in very aggressive environments. Belzona offers cost-effective solutions which reduce downtime and labour costs whilst eliminating the need for equipment replacement.

Solids handling equipment restoration and protection

Solids handling equipment is continually exposed to heavy wear due to the nature of the processed materials. Belzona offer a wide range of metal and rubber repair materials which can be used to repair and protect screw conveyors, conveyor belts and drive rollers.

Ceramic reinforced epoxy repair composites, such as Belzona 1811 (Ceramic Carbide), are designed to rebuild damaged screw conveyors and provide long-term abrasion resistance for many years. Belzona rubber repair materials, including Belzona 2111 (D&A Hi-Build Elastomer) and Belzona 2311 (SR Elastomer), can be used for flexible repairs, including worn conveyor belts and heavy duty tyres, without the need for hot vulcanisation or disassembly. Additionally, by incorporating slip reduction systems, such as Belzona 1821 (Fluid Metal), belt slippage can be eliminated and drive rollers protected from abrasion and corrosion.

Abrasion damage repair and protection

Belzona abrasion resistant linings can be used to repair and protect pipe elbows, chutes and hoppers. Designed to significantly reduce the effects of abrasion by providing a sacrificial lining, Belzona 1812 (Ceramic Carbide FP) offers huge savings with regards to both time and cost.

Where impact protection is required, materials from Belzona's 2000 Series can be used to provide a sacrificial lining to protect against impact damage. These materials are tough, flexible, easy to apply and fast-curing, allowing a quick turnaround when compared with replacement.

Fluid and gas handling equipment repair and protection

Severely damaged pumps in the mining industry, including liquid vacuum and centrifugal pumps, can be restored to their original profile and protected against the effects of erosion, corrosion, chemical attack and deterioration. Cold-curing materials, such as Belzona 1212, can be used to repair pump cracks and holes in situ, while materials such as Belzona 1311 (Ceramic R-Metal), help to provide outstanding chemical resistance.

Belzona’s range of coatings, such as Belzona 1321 (Ceramic S-Metal), provides long-term erosion and corrosion resistance. Furthermore, Belzona 1341 (Supermetalglide) is proven to increase pump efficiency up to 7% on new equipment and up to 20% on refurbished equipment.

Mechanical equipment repair

Mechanical equipment suffering from bearing vibration, wear and lubrication loss, such as shafts and engines, can be repaired using an array of cold-applied materials. Among these, Belzona 1131 (Bearing Metal) will reduce friction at start up by trapping and holding lubricating oil. Bearing housing failures can be quickly repaired with fast-cure materials such as Belzona 1212, which is specifically designed for emergency repairs, reducing downtime.

Protection from chemical attack

Belzona epoxy repair composites and coatings provide outstanding chemical resistance against a wide variety of harsh chemicals for equipment including chemical storage tanks and leach tanks. For instance, coatings such as Belzona 4311 (Magma CR1) are ideally suited to protect secondary containment areas from contaminated chemicals and Belzona 5811 (Immersion Grade) is excellent for protection of equipment operating under continuous immersion.

Chocking and shimming solutions

Due to the severe impact and vibration within the mining and quarrying industry, misalignment of machinery and equipment can occur frequently, leading to efficiency loss and equipment damage. For loose bearing pins and bush housings and incorrectly fitting components, Belzona 1111 (Super Metal) is ideally suited, whilst Belzona 7111 is a pourable chocking compound is specially formulated to spread out evenly across irregular surfaces. Once cured, this provides maximum support to plant and equipment.

Facilities maintenance

Belzona's materials provide a cost-effective solution to maintenance problems by minimising downtime, labour and equipment replacement costs whilst optimising efficiency and reliability. Belzona can provide solutions for the repair and protection of your facility, including:

  • Liquid-applied, flexible roof membrane for weatherproofing buildings, structures and insulation
  • Concrete and stonework repair and protection systems
  • Environmental barrier polymers to protect against and reduce environmental impact
  • Safety surfacing polymers for the reduction of slip hazards
