Life never quite works out how you want it to. Conveyor belt life is no exception.  If belt cover and carcass was to wear out simultaneously, you could say you have achieved optimum life. But in the real world instead of your dreams, that never happens. The belt cover wears through. The carcass stays intact. But the whole system’s life expectancy is compromised.

 

At best, the conveyor will have to be removed from service long before its time. At worst, the damage could lead to catastrophic failure, loss of production, unscheduled maintenance downtime and even injury.

So if life doesn’t live up to your dreams, can you at least make it less of a nightmare?

Dare to repair

Even a running repair has to be tough enough to withstand normal working conditions. And if the tensile strength of the carcass on the damaged belt isn’t sufficient to withstand drive and take-up forces, then replacing the section is almost certainly the best and safest option.

But if only the cover is damaged – even across a large area – there’s a simple, secure and speedy solution.

Based on polyurethane technology, LOCTITE has just what you need for a proven, lasting repair even in the most hostile of environments. LOCTITE’s polyurethane adhesives are suitable for a huge range of applications, because they’re available in everything from highly rigid to extremely flexible grades.

LOCTITE PC 7350 is a one flexible formulation that’s designed specifically for conveyor belt repair.

 

Quick cure

LOCTITE PC 7350 is a two-part polyurethane compound that cures quickly at room temperature. So it’s ideal for on-site running repairs of conveyor belts and numerous other rubber parts too: including rebuilding liners in mills, pumps, feeding bowls, hoppers and chutes, and repairing cast urethane screens and liners.

All you have to do is abrade the damaged area to create a uniform surface, apply a LOCTITE etching agent, and wait for up to a minute for it to dry. Then the belt is ready to repair. 

Attach the mixing nozzle to the LOCTITE PC 7350 cartridge, and apply the adhesive to the primed surface before smoothing it using a plastic spatula. (The product is self-levelling, so there’s no need for perfection.)

A US mining company uses this system on its stone conveyors, and has restored belts to full working order within just two hours. And an Australian manufacturer has achieved repairs to the same timescale – in a ship-loading application that had been losing up to £7,000 per hour through delays caused by belt damage.
