Introduction to Conveyor Belt Damage
With over seven decades of experience in mining solutions, Belzona highlights the top five areas where damage is most prevalent in the post – Mining and Quarrying: Belzona’s Top 5 Application Areas. Damaged rubber components and equipment are among the critical issues in the mining industry, usually found in the conveyor systems. In this blog post, we focus on how to repair conveyor belts with Belzona elastomeric polymers.
Belzona 2000 Series for Rubber Repair and Protection
Belzona 2000 Series, cold-cure polyurethane materials, offer alternative solutions for rubber repair and protection. By using these cold-cure materials, asset owners can carry out conveyor belt repairs in situ, without the need for specialist tools, thus eliminating the need for hot work and minimizing downtime. This ensures a fast return-to-service. Moreover, they offer a versatile repair where durability and elasticity, as well as good abrasion and tear resistance, are required.
Belzona 2311 (SR Elastomer) for Conveyor Belt Repair
In the following section, we demonstrate how to use Belzona 2311 (SR Elastomer) to repair a ripped conveyor belt. Belzona 2311 (SR Elastomer) is a two-component, rapid-curing elastomeric polymer for emergency and permanent repair. The solution provides outstanding protection against wear, impact, and abrasion. Asset owners can perform repairs directly on conveyor belts without the need to disassemble them, ensuring minimal disruption to operation.
Step-By-Step Guide: How to Repair Conveyor Belts with Belzona 2311 (SR Elastomer)
STEP ONE
Terminate the tear by drilling holes at each end of the tear.
STEP TWO
Undercut the defected area with a sharp knife to leave a sound edge.
STEP THREE
Remove the top layer of the defined area on the conveyor belt.
STEP FOUR
Abrade the surface with a rotary wire brush or a suitable roughing tool to achieve a woolly finish.
STEP FIVE
Brush away any loose contaminants on the conveyor belt.
STEP SIX
Cover the underside of the tear with a pre-cut tape to prevent the products from leaking through the hole.
STEP SEVEN
Define the area on the conveyor belt using a tape.
STEP EIGHT
Apply Belzona 2911 (Elastomer QD Conditioner) to the repair area.
STEP NINE
Once Belzona 2911 (Elastomer QD Conditioner) is touch dry, start mixing Belzona 2311 (SR Elastomer). Note that Belzona 2311 (SR Elastomer) has a short working life so Belzona recommends strictly following the Instructions for Use for optimal results.
STEP TEN
Use the Belzona applicator to apply Belzona 2311 (SR Elastomer) on the targeted repair area.
STEP ELEVEN
Wet out Belzona 9341 (Reinforcement tape) with Belzona 2311 (SR Elastomer) and embed the tape into the repair area.
STEP TWELVE
Encapsulate the tape with the remaining Belzona 2311 (SR Elastomer) system.
STEP THIRTEEN
Once the product is cured, remove the tape. Now, the application is complete.
