MULTOTEC RUBBER MD ACKNOWLEDGED BY IOM3

Spike Taylor, managing director of Multotec Rubber, was recently acknowledged by the Institute of Materials, Minerals and Mining Southern Africa (IOM3) for the significant role he has played in the industrial rubber industry since 2002.

At the 24th IOM3 National Rubber conference, held in Cape St Francis, in April this year, Taylor was awarded the John Tallant Medal for Outstanding Merit for this contribution. The local arm of the international IOM3, established more than 60 years ago, is made up of representatives of the South African industrial rubber sector.

Taylor, who has a B.Sc. Engineering Metallurgy, began his career at De Beers and in 1985 joined Multotec as a sales engineer. He progressed through the organisation and in 2009 was appointed as the managing director of Multotec Rubber.

Multotec Rubber is primarily focused on the local manufacture of rubber and rubber composite grinding mill liners and established its local manufacturing plant in Spartan in 2000. The company can point to more than 400 successful mill and scrubber liner installations across Africa. This, Taylor says, does not include those installations in countries outside of Africa.

Referencing recent installations, Taylor says these include an AG mill lining on a diamond mine in East Africa, a lining in a secondary ball mill on a platinum mine on the South African western Limb, two scrubber linings on a phosphate mine in North Africa and a SAG mill lining for a Zambian copper mine.

“In addition to these, Multotec Rubber has significantly increased its footprint in West Africa with the installation of three ball mill linings and a SAG mill lining at gold plants in this region,” he says.

In all instances, the Multotec product replaced competitor lining. Taylor attributes this to the focused approach of the Multotec Rubber team to leverage mill liner technology to ensure customers receive the benefit of the company’s extensive knowledge facilitating optimum recoveries.

“By maintaining the high road when it comes to product quality and product consistency, we have been able to prove to customers that those who accept inferior product because of lower pricing do inevitably pay for this over the long run with production issues,” Taylor concludes.

CLIP FASTENER LEADER MATO MAKES ITS MARK IN BELT CLEANERS

Well-known for its mechanical conveyor belt fastening systems, Multotec company Mato Products is now also leading the charge in innovative belt cleaning systems.

Mato Products has long been a household name in clip fasteners for conveyor belts, especially in the underground coal sector. The company operates one of only three high production Mato machines in the world, and significantly the only one outside of Germany. After over 30 years of operation, the unit was overhauled in 2016 in an intense six month refurbishment. It was upgraded from 180 tonne to 360 tonne capacity, speeding up production and ensuring both ongoing cost-effectiveness and reliability of supply for customers.

The company’s exciting line of belt cleaning equipment has for some time now been gathering momentum. Its popularity has extended well beyond the coal sector into other materials handling and mineral processing applications, even in diamond mining. According to Benjamin Sibanda, managing director of Mato Products, over-feeds at transfer points often lead to material build-up on the inside of a belt.

“As mines and other industrial facilities raise their environmental standards, they want to avoid problems like duff heaps under conveyors, which can cause pollution,” says Sibanda.

The Mato MCP3-S primary cleaner, installed at the head pulley is designed to be an aggressive head pulley cleaner, yet friendly to the conveyor belt surface and suitable for use with mechanical fasteners. It offers a high level of cleaning due to its blade profile, and the spring tensioning system ensures the blade is in constant contact with the belt for the life of the blade while achieving up-to a maximum of 75% cleaning.

“The secondary Mato MUS2 belt cleaner is one of our latest design belt cleaners and offers a M-TRAK slide on cushion and blade for easy installation and maintenance” Sibanda says.

The unique M-TRAK is designed to eliminate lengthy maintenance downtime and ensures blade alignment is 100% true across the entire conveyor belt width. Blade replacement is also very simple with the design of the slide-on and slide-off principle, eliminating the need for special tools or training when maintenance is performed.

“The unique design of our MUS2 cushion is based on the principle of a parallelogram whereby the cushion also stays true to the conveyor belts surface ensuring the angle of attack is maintained,” he says. “This cleaner’s primary duty is to remove fines and duff, to almost zero carry-back.”

Blades on the cleaners come in a range of materials suited to different applications, including polyurethane and tungsten.

While the application in South Africa was initially mainly underground, equipment variations for surface have now also been developed and introduced to market. The plant tail-end cleaner is based on the same concept but is mounted on channels rather than on stringer pipes.

“This product includes innovative blade stoppers,” Sibanda explains. “When the blade is worn to a certain level, the mounted flat plate does not touch the belt, for better protection.”

Leveraging its technical expertise and experience in the market, Mato Products has also engineered closer integration between its fastener clips and the belt cleaners.

“For instance, we have added a profile to the clip which optimises the life of both the clip and the tungsten tip on our secondary belt cleaner,” he says. “The skiving process embeds the clip slightly into the belt ensuring the mechanical splice is on the same surface as the conveyor belt thereby minimising the impact on the tungsten tip as well as lowering noise levels. Longer life of both means less downtime for the customer and greater reliability.”

Sibanda highlights that all the offerings in Mato Product’s conveyor belt systems range helps to improve the lifespan of equipment at loading points. The energy of ore transfer is absorbed, and wear resistance is increased by Multolag ceramic products.
