Cleated belts are a common sight across Australia quarries. They stop free-flowing materials from rolling back down the conveyor and are especially useful in systems with high angles.

Due to their design, traditional belt scrapers cannot be used with the belts, leading to the question, how do you clean the conveyor?

Without the right cleaning systems in place, carryback can quickly build up on the belt. This build-up can migrate to the rollers, leading to mis-tracking and potentially damaging one of the most expensive components of a conveyor.

It can also lead to increased dust and spillage, creating hazards for nearby workers.

Peter Laskey, a field applications specialist at Kinder Australia, told Quarry that there is a solution – the K-Cleatscrape.

Fitted where a secondary belt cleaner would normally be installed, the K-Cleatscrape uses 200mm polyurethane blades with stainless steel or tungsten tips to reach stubborn carryback.

What makes the belt cleaner stand out is its finger-based design, allowing the cleaner to go over the cleats without damaging like a conventional spring-tension cleaner might.

“Traditionally, to clean a cleated belt would require the use of a brush cleaner, but even then, if the cleats are higher than usual they are unlikely to be effective,” Laskey said.

“Motorised brush cleaners require a power source, and a static brush needs constant adjustment, leading to wear.

“In a lot of cases, constantly passing over a cleated belt at a certain angle can lead to a scraper losing its memory and flattening.”

There are several different levels of hardness available for the K-Cleatscrape to ensure they have the maximum cleaning effectiveness for cleats up to 100mm in height. The unique design is compatible with mechanical belt splices and helps to ensure old and worn belts are not damaged, further extending the service life of the conveyor belt.

The proprietary finger design ensures even and optimal belt scraping, with a double row of off-set combs to accommodate extreme ridges.

Old and worn belts avoid additional wear, as the cleaner is forgiving when it comes up against mechanically fastened splices, belt cover gouges or other belt damage imperfections.

Laskey said the effective and inexpensive cleaners have proved popular among Australian quarries.

“Our customers have been very satisfied with the K-Cleatscrape. They’ve gone from having no easy solution for cleaning cleated belts to a simple, easy solution,” he said.

“It’s saving them time and stopping carryback. It’s a simple design that’s strong enough to handle the job it needs to do.”

Kinder’s field application specialists work closely with quarries to find the right tool for the job.

Laskey said the company wants to support the quarrying industry as much as possible, and new components like the K-Cleatscrape is one way it can do that.

“Innovations help us solve the big problems we have found on sites,” he said.

“We’re a solutions-based company. That means we can come in and help quarries with the difficult engineering problems they’re facing.”
