In mining, minor equipment damage can quickly develop into an unplanned shutdown with a direct impact on production.

One of the greatest challenges is the time required to complete a reliable repair and return equipment to service. Even relatively simple repairs can take hours or days because of complex disassembly, component replacement, or long cure times, affecting critical equipment availability.

Damage such as a cut in a conveyor belt, progressive wear in a chute, or loss of wall thickness in a hydrocyclone can compromise equipment integrity. These conditions can also lead to emergency repairs, higher maintenance costs, and increased pressure on operations and maintenance teams.

Repair speed is critical, but it must be combined with reliability, correct application, and adequate performance under the equipment’s actual operating conditions. Depending on the product selected and the specified application conditions, FLEXSOL® and DURAFAST® systems can help return critical equipment to service in approximately one hour.

The Hidden Cost of Slow Repairs

At many mining sites, the total cost of corrective maintenance depends not only on the repair materials used, but also on how long the equipment remains out of service.

When a repair requires component disassembly, long cure times, or repeated maintenance work to correct premature failures, the operational impact can be considerable.

Material cost usually represents only part of the equation. The greatest economic impact often comes from equipment downtime, the associated loss of production, and the additional resources required to restore operation.

The priority for maintenance teams is not merely to repair the damage, but to do so quickly and safely using a solution that provides the required performance under the equipment’s actual operating conditions. This is the principle behind the polymeric repair and protection systems we develop.

What Are the Most Common Challenges in Protecting and Repairing Mining Equipment?

Certain operating conditions accelerate wear in critical equipment and components. Continuous abrasion, impact from coarse material, vibration, and exposure to aggressive environments can cause damage that, if not addressed promptly, may lead to unplanned shutdowns and higher maintenance costs.

These challenges are compounded by the constraints of many onsite repairs: hard-to-reach areas, short maintenance windows, and the need to return equipment to service quickly.

Repair and protection solutions used in mining must therefore address both the mechanical demands of the process and the need to maximize operational availability.

DURAFAST®: Protection Against Abrasion, Impact, and Severe Wear

The DURAFAST® line consists of rigid, fast-curing, two-component epoxy systems designed to repair and protect steel, ceramic, and concrete substrates exposed primarily to severe abrasion and moderate impact.

These systems can be applied directly onsite to equipment such as chutes, hoppers, hydrocyclones, pumps, mills, and crushers, helping reduce repair time and facilitate the return to service.

DURAFAST® MX1 for Coarse-Particle Wear

DURAFAST® MX1 is intended for applications where abrasion and impact from coarse material cause accelerated material loss and localized damage.

Its key advantages include high adhesion to steel, concrete, and ceramic substrates, as well as resistance to severe abrasion and moderate impact. This helps extend equipment service life and reduce recurring corrective repairs without requiring the replacement of entire components.

DURAFAST® MX2 for Fine-Particle Wear

Fine-particle abrasion can cause localized erosion and gradual loss of wall thickness, eventually leading to leaks and unplanned shutdowns.

DURAFAST® MX2 was developed to address this type of wear in equipment such as cyclones, pumps, ducts, piping, elbows, pneumatic conveyors, screw conveyors, and material transfer components.

Its thixotropic, non-sag consistency enables controlled application on vertical and overhead surfaces. This helps ensure uniform coverage in hard-to-reach areas and supports more precise onsite repairs.

Mining operating requirements can vary significantly from one site to another. However, abrasion, impact, aggressive environments, and the need for onsite repairs are common challenges across mining operations. DURAFAST® solutions can help restore and protect components exposed to these demanding service conditions.

FLEXSOL®: Repair and Protection of Rubber and Metal Surfaces

Conveyor belts, pulleys, and rubber-lined components are continuously exposed to cuts, tears, abrasion, impact, vibration, and movement. If this damage is not repaired promptly, it can spread and lead to more complex repairs or premature component replacement.

The FLEXSOL® line consists of fast-curing polyurethane elastomers designed to repair, rebuild, and protect rubber and rubber-to-metal applications while maintaining flexibility.

FLEXSOL® BF-01 for Conveyor Belt and Rubber Component Repair

FLEXSOL® BF-01 is a liquid polyurethane elastomer designed for horizontal repairs on rubber surfaces affected by cuts, wear, and localized damage.

Its formulation restores surface continuity while maintaining the flexibility required by rubber components. This helps extend the service life of conveyor belts and other rubber components and helps prevent minor damage from developing into more complex repairs.

Common applications include conveyor belt repair and the manufacture, repair, or rebuilding of molded rubber components.

FLEXSOL® BF-02: A Solution for Rubber and Metal

Many pieces of mining equipment combine metal surfaces with rubber linings. These transition areas are particularly demanding because rubber and metal respond differently to impact, vibration, and movement.

FLEXSOL® BF-02 is a liquid polyurethane elastomer designed for horizontal applications requiring adhesion to both rubber and metal. It maintains the flexibility and abrasion resistance required in mixed-substrate repairs.

Common applications include repairs on conveyor belts with exposed steel cords and the rebuilding or maintenance of components that combine rubber and metal surfaces.

FLEXSOL® BF-03 for Vertical and Hard-to-Reach Repairs

Some repairs must be performed on vertical, inclined, or complex surfaces where liquid materials may be difficult to control.

FLEXSOL® BF-03 has a paste-like, non-sag consistency designed for horizontal and vertical applications. This facilitates repairs on inclined surfaces and complex geometries without requiring equipment disassembly.

Common applications include the rebuilding and maintenance of pulley linings, hydrocyclones, tanks, elbows, conveyor belts with exposed steel cords, and other rubber or rubber-to-metal components.

More Than a Repair: Operational Continuity

A repair and protection system should not be evaluated solely on its technical data.

Its value also depends on how effectively it extends equipment service life, reduces downtime risk, and supports operational continuity.

FLEXSOL® and DURAFAST® solutions were developed to provide fast, durable repairs that can be performed directly onsite, enabling mining operations to restore critical equipment without unnecessarily extending shutdowns.

When a repair is performed correctly the first time, maintenance becomes a strategic tool for protecting equipment availability and sustaining operational continuity.
