MLT Group has devised the Super-Screw for heavy-duty conveyor rubber belt splicing and joining to address a common pain point for customers.
Three French coal mine engineers came together in 1945 and decided there was no “optimal way” to repair conveyor belts available to them.
They began creating quick-join solutions to solve the issue.
More than 75 years later, in this seminal moment in the company’s history, MLT Group has created the market’s only Super-Screw splice join to provide operators with optimal solutions.
MLT’s Super-Screw is designed for conveyor belt specifications and set-up with cleaners and scrapers installed along conveyors.
This permanent solution is available in various specifications to suit most conveyor belts in quarry and mining applications. MLT Super-Screw ranges are available with various options, in abrasion-resistant rubber, in very high abrasion-resistant with premium hard-wearing polyurethane material, in stainless steel for metal detectors or corrosive environments, in FRAS to ISO 340 & ISO 284 standards, in heat resistant/retardant up to 200˚Celsius and for low temperature down to -30˚Celsius.
The MLT Super-Screw steel screws and inserts are of high tensile with great mechanical resistance and are the ideal choice for quarries and cement plants.
MLT has designed and manufactured the Super-Screw to use high tensile screws and inserts to make it easier to install when compared with competitor products.
“Our solution is a permanent solution, some people may think it is a temporary solution, but it is not, because of the Super-Screw design,” MLT Group Australia general manager Peter Oudomvilay told Quarry.
“The high tensile screws and inserts themselves are specially designed; this has now been used for more than 30 years around the world and more than 15 years in Australia.”

On the New South Wales Central Coast, a coal-powered power station suffered from repeated emergency belt breakdowns on its feeder conveyors.
When the company approached MLT Group, it was clear that any worthwhile solution needed to be a permanent type, easy to install, quick, and without requiring additional templates or special toolings for on-site installation.
The MLT Super-Screw proved to be the ideal solution to get conveyor belts up and running again.
Oudomvilay has seen this situation in phosphate, iron ore, coal, copper, and nickel mines as well as quarries. When conveyor belts break or are damaged, an effective, seamless solution is required.
This is why MLT’s Super-Screw are turning into popular options for site, maintenance managers, plant operators, and belt splicers across Australia.
The MLT Super-Screw allows belt splicers to repair and join belts, which only require cordless skivers and drill drivers to do the complete installation.
“The traditional way of joining conveyor rubber belts is by hot weld using a vulcanising press or cold join using glues and chemicals,” he said.
This process lets the rubber or fabric melt or bond into each other.
“Usually, that takes the whole day or more and requires a crew of six or eight people. “For a solution like the Super-Screw, you only need two to three people, and this can be done in a couple of hours with the conveyor belt up and running in no time.”
The company, which began in France more than 75 years ago, created its Super-Screw solution over three decades ago.
“We find that when customers are previously unaware of our products, they become quite pleased with the time they save and the effectiveness and durability of the splice joins after installing our Super-Screw,” Oudomvilay said.
MLT opened its Australian subsidiary in 2008 before it became MLT Asia Pacific seven years later under the complete control of the MLT Group France.
Customers receive high-level support and technical advice. All MLT products are manufactured in France and come with certificates of authenticity to prove their quality.
Oudomvilay said customers can work with MLT Asia Pacific to create tailored solutions for their Australian applications and conditions.
“Once they use them, we hear positive things about the time-saving, effectiveness, and durability of the products,” he said.
“When you lack personnel, lack time for maintenance downtime, and are faced with production deadlines, this is one of the options you can consider as opposed to conventional methods. This is a quick and permanent solution.”
