“As in previous phases of the mine’s development, our robust high quality power packs will provide reliable solutions in on-site applications such as conveyors, agitators, and slurry pumps,” says Strydom. “The size range in the order makes use of our wide capability range to provide a total solution, ranging from 55 kW units to 500 kW units.”

The latest order includes several X.e Series power packs for conveyor applications, planetary gearboxes for feeder applications, and spare gearboxes. The equipment will be delivered in staggered shipments this year. While the mine typically undertakes the installation of the equipment, SEW-EURODRIVE sends technical teams to site to check final alignment and overall installation parameters.

The tropical climate as well as high levels of sun exposure meant that SEW-EURODRIVE had to take special care in their design, incorporating special breathers, covers and fans.

The company has expanded its after-sales service teams considerably in recent years, allowing it to support the growing base of equipment throughout Africa. Its projects and engineering teams have also grown – developing a depth of experience to assist customers right from design phase onwards.

Strydom notes that SEW-EURODRIVE has significantly developed its infrastructural foundation in South Africa, and plans to develop a physical representation in over 23 other African countries. As a priority country for the company’s strategy, there is expected to be a representative in place in the DRC in 2023, he explains. Field service teams from South Africa are frequently at Kamoa-Kakula to assist with servicing of the existing power packs operating on the site.

“Our local assembly capability in our new facility in Johannesburg – combined with our ability to source from the group’s other global operations – has allowed us to meet the tight delivery deadlines for this substantial order of equipment,” he says. “Our global footprint and production capacity mean that we can deliver faster than most players in our field, and this is often an important factor for our market.”

While the company previously imported the larger X.e Industrial gearboxes from Germany, it is now able to assemble these in the new South African facilities. As part of its service, SEW-EURODRIVE will also handle the logistics of getting this large volume of equipment to site. The company’s training centre – the Drive Academy – in Johannesburg has also made a valuable contribution by providing training on the equipment and its maintenance.

In this project, the tropical climate was another important factor in the customer’s design requirements. This required the inclusion of certain cooling and paint specifications in the contract. SEW-EURODRIVE Head of Engineering Andreas Meid explains that special breathers were part of the design in response to high humidity levels – and served to ensure no moisture in the gearboxes. In outdoor applications where sun exposure was high, covers were also included to reduce heat build-up. Cooling fans were also optimised in certain cases to ensure optimal performance.

He highlights that Kamoa-Kakula is one of many projects in Africa to request the installation of monitoring equipment on the power packs. This facilitates real-time monitoring, using specialised sensors to measure key indicators like vibration and temperature from anywhere in the world.

“This allows the operation to monitor the equipment remotely, receiving early warnings of any issues in performance,” says Meid. “Responding timeously to this information can prevent serious damage and avoid unplanned downtime.”

As a preferred supplier, SEW-EURODRIVE first delivered a multitude of X.e Series power packs between 2019 and 2021 for the mine’s initial development phase. Motors ranging in motor from 7, 5 kW to 500 kW as well as planetary gearboxes were supplied during this time for feeder applications, together with several spare gearboxes.

For Kamoa-Kakula’s Phase 2 expansion, which doubled the concentrator plant capacity, SEW-EURODRIVE supplied many standard X.e Series power packs for the conveyors as well as planetary gearboxes for the feeders.

OPTIMISING TRANSFER POINTS IN BROWNFIELDS PROJECTS

As mining companies embark on brownfields initiatives to meet rising market demand for battery and other minerals, the optimising of transfer points presents a valuable opportunity to deliver more output cost effectively.

Alwin Nienaber, Technical Director at Weba Chute Systems, says that when correctly used technology and experience provide a powerful combination when expanding production capacity. Technology can be leveraged to facilitate rapid and accurate scanning of the existing configuration of infrastructure into which the improved chutes are to be installed. Further, he says, the company brings a wealth of expertise to advise on valuable adjustments in the relationship between chutes and other equipment.

“Custom engineered chutes and transfer points have been shown to facilitate smoother flow of mined material, with greater reliability and uptime for a more streamlined and productive operation,” explains Nienaber. “The initial focus when providing transfer point solutions to a brownfields project is usually to take careful note of the physical layout so that chutes are designed with spatial constraints in mind.”

This can be most accurately and efficiently achieved using 3D laser scanning of the existing layout, to rapidly gather detailed measurements of large infrastructure on a customer’s site. Using this data, a precise 3D model can be generated on the basis of which the necessary chutes and componentry can be designed and manufactured.

“This aligns well with Weba Chute Systems’ considerable in-house expertise in chute design, as each chute we build is unique to the application it serves,” Nienaber says. “It is important to remember that every transfer point exists in a relationship to other equipment, such as a screen, crusher or conveyor belt.”

He highlights that an understanding of this relationship will underpin the productive application of transfer point design and installation. Indeed, while the 3D scanning and modelling technology provides a valuable starting point for design there is also scope for added improvements in the plant layout.

“On so many of the sites that we visit and assess, we can soon identify where changes in the relationship between the transfer points and other equipment can deliver better results,” says Nienaber. “While it is sometimes difficult – even costly – to implement some of these changes, the customer reaps many times the value in terms of uninterrupted volume flow, uptime and productivity.”

The first prize when installing transfer points, he emphasises, is always the optimal solution – which may mean reconsidering the position of the upstream and downstream equipment. In fact, this is always the starting point for Weba Chute Systems’ transfer point solutions: to achieve the most productive result for the customer.

“With our engineered design approach, we always consider the context of where our chutes are going to operate, and our decades of field experience allow us to advise the customer what will work best,” he says. “We might advise on how adjusting the position of a conveyor’s head pulley, for instance, would improve chute performance and overall plant efficiency.”

He notes that, while certain configuration changes might exceed budget constraints, the company’s intervention often allows for positive modifications to be made. A recent example of this was in a contract for a South African iron ore producer in the Northern Cape. Weba Chute Systems was asked to address the mine’s challenge where an existing competitor’s chute needed attention every two days  which was severely hampering production.

“We designed and installed the optimal customised chute, but also recommended some related adjustments,” he says. “The design was a split chute, and the plant needed to speed up its conveyor quite considerably – as well as lifting the head pulley slightly – to achieve the necessary results.”

The changes recommended had financial implications, so the customer required considerable certainty that the solution would be successful. To underpin its plan, Weba Chute Systems digitally modelled the proposed design and simulated its operation using software that visualised the movement of material through the chute.

“Used by our skilled designers, this powerful software delivers more than a pretty picture,” emphasises Nienaber. “The simulation presents in video format exactly how equipment will be positioned and how material will flow through the system.”

Fundamental to these kinds of solutions, of course, is a close collaboration with the customer, built on a high level of trust in the company’s past performance. Aligned to this is Weba Chute Systems’ commitment to see through any project it embarks upon, he says.

“Our customers know we never walk away from a project – and this is an important factor in brownfields projects where one is often working within existing constraints rather than a clean slate,” he argues. “We have confidence in our people and our designs, and remain accountable for any solution we provide until it performs to levels we have promised.”

Another important factor in many projects is the level of degradation of mined material, which the company prides itself on reducing through its scientific, streamlined approach to the dynamics of bulk materials handling.

“An example of where this was important was a steel plant in Turkey where we installed a number of our chutes,” he explains. “The customer required minimal ore degradation, and even monitors the ore passing through each chute to ensure fines generation is kept to a minimum.”

Weba Chute Systems was required to incorporate samplers in its installations in this plant, and these samplers generate the data to verify the chutes are performing to expectation. The company’s custom design allows greater control over the direction, flow and velocity of material, whose volume and characteristics are specific to each application.

TRAFO SERVES GROWING DEMAND FOR MODULAR SUBSTATIONS

Dry-type transformer specialist Trafo Power Solutions has broadened its offerings to include modular substations – leveraging the company’s depth of experience in designing and providing custom engineered electrical solutions.

“Since our entry into the market supplying dry-type transformers, we noticed an increasing demand for complementary systems related to their application,” says David Claassen, Managing Director of Trafo Power Solutions. “Our evolution began with customer recognition of the level of our in-house expertise, and requests for packaged solutions which included our dry-type transformers.”

Dry-type transformer specialist Trafo Power Solutions has broadened its offerings to include modular substations.
Dry-type transformer specialist Trafo Power Solutions has broadened its offerings to include modular substations.

Customers needed a reliable supply partner with the competence and experience to understand the specific demands of each project and application, says Claassen. Trafo Power Solutions has proven itself in this role, right from the concept and design stage of a project through to facilitating the manufacture, delivery and on-site commissioning.

He notes that modular substations, often referred to as E-house, are prefabricated or modular structures that house electrical equipment and systems. They are designed to provide a centralised and secure environment for critical electrical components and infrastructure. Often used in industrial settings, power plants, mining operations, oil and gas facilities and other applications where reliable and efficient electrical power is essential, an E-house would house a variety of electrical equipment such as switchgear, transformers, motor control centers, distribution panels, and other power distribution and control devices.

Modular substations are built and tested in controlled workshop conditions, making the process more streamlined and cost effective, and ensuring optimum quality.

“Most significantly, modular substations are built and tested in controlled workshop conditions, making the process more streamlined and cost effective, and ensuring optimum quality,” he continues.

“Dry-type transformers are perfectly suited to the philosophy of modular substations, as they can be safely accommodated inside the compact structure enhancing the benefits that modularity brings,” he says. “The attraction of the modular structure is that it can be more easily transported and installed on site – and having a built-in transformer just makes sense.”

Traditional oil-cooled transformers must be installed in a purpose built structure for safety reasons, as there is a risk of leakage, fire or explosion. This often means extra civil engineering construction on site, adding time and resources to the project. The cabling arrangement between the external transformer bay and the substation must then also be accommodated.

“The inherent safety of the dry-type transformer allows it to be installed close to the switchgear inside the modular substation, so there are shorter cable runs and easier installation,” he explains. “The extra cost and management of on-site civils work are also avoided this way.”

Increasing its solutions offering has bolstered the standing of Trafo Power Solutions in the market, as it no longer supplies just a single component, he continues. The company now provides a packaged and integrated solution that minimises its customers’ points of contact during their projects – be they an end-user or an engineering, procurement and construction management (EPCM) company.

“Not only does this save them time, but it also considerably reduces the risks associated with integrating the different aspects of electrical projects,” says Claassen. “There is certainly a trend in the market where customers are looking for more integrated solutions, which allows better quality control and ease of installation.”

He notes that the transition to a broader offering has been quite natural as Trafo Power Solutions has never just provided standard off-the-shelf transformers. It has always customised this equipment for each specific application, requiring an in-depth understanding of the customer’s needs before tackling the design process.

“Within our company, we have strong engineering expertise and experience so it was a spontaneous transition into dealing with the other aspects of modular substations,” he says. “We were always well acquainted with these broader elements in any event, as they informed the design of our transformers.”

This has opened up opportunities for Trafo Power Solutions in a range of industries, many of which may not previously have considered the modular substation concept in their project planning. Increased interest is evident in sectors such as data centres, oil and gas, food and beverage and renewable power generation.

The company has in recent years designed and supplied containerised transformer solutions for mining customers including the remote Bisie mine in the north-eastern Democratic Republic of Congo. So successful were these units that the mine recently ordered three more substations, again equipped with dry-type transformers.

“We expect the trend towards modular substations to continue strongly,” says Claassen. “We have, for instance, delivered multiple modular substations to a large data centre in Johannesburg. Here, we have provided a full medium voltage modular solution including switchgear and transformers, complete with cooling and control systems.”

Trafo Power Solutions is also engaged in the manufacture of almost 40 mini-substations with dry-type transformers, following a large order from a copper mine in southern Africa. In all its transactions, the company is able to design and provide the required equipment with a quick lead time, ensuring customers of on time delivery and on budget, he concludes.
