Weir Minerals wins large comminution order from Nigeria iron ore mine

Two of the largest screens built by Weir Minerals Africa are being designed and manufactured in South Africa as part of a process solution for an iron ore mine in Nigeria.

According to Tiisetso Masekwameng, General Manager Comminution at Weir Minerals Africa, the flowsheet accepted by the customer includes equipment for screening, washing, and grinding supplied by Weir Minerals.

“Within our scope of work are the two largest Enduron® double-deck banana screens built by Weir Minerals,” Masekwameng says. “This is made possible by the depth of design expertise in our Separation Technology Group, an eight-strong team conducting research and development.”

Steven Hunter, Separation Technology Group Leader at Weir Minerals Africa, says the two 51 t Enduron double-deck banana (DBHG 43/97) screens (one pictured) for this project were built upon the designs of the existing Weir Minerals screens range. These large machines measure 4.3 m wide and 9.7 m long and can process 1,750 t/h.

“The customer’s production requirements demanded this considerable size, so we optimised the design by minimising mass without compromising structural integrity,” Hunter says. “We conducted extensive finite element analysis on the whole machine but focused on the main structural elements, ensuring that the units were fit-for-purpose while still being light enough to be driven by the exciters.”

The size of the units still demanded the design and manufacture of Weir Minerals Africa’s largest exciter yet – the Enduron LTX 10. With 120 t of excitation force (at maximum setting), these units will drive the screens at a stroke of 9.4 mm and a gravitational force of 4.6 G.

Hunter said the screens are ready to be fitted with Weir’s IIoT platform, Synertrex. “This allows the machines to be monitored remotely; the system can measure the machine’s performance and any deviations arising that may require proactive attention,” he explained.

The order for Nigeria also includes two Trio® jaw crushers, two Trio cone crushers, two large 2 m by 8 m Trio apron feeders, two Trio pan feeders, eight Enduron vibrating screens and an Enduron HPGR.

For the clay washing circuit, Weir Minerals Africa will supply the mine with a Trio twin-shaft blade mill and Trio twin-shaft coarse washers as well as Warman® slurry pumps.

Weir Minerals strives for unmatched hydrocyclone performance with release of Cavex 2

Almost 25 years after the original Cavex® hydrocyclone came into the classification market, Cavex 2 is set to introduce a step-change in performance and sustainability, with water and energy savings, according to Weir Minerals.

The launch of Cavex 2 marks a new generation of hydrocyclones, Weir says. Like the original Cavex hydrocyclones did more than two decades ago, Cavex 2 introduces new geometric features to offer performance unmatched by any cyclone in operation today, the company claims.

Debra Switzer, Global Product Manager for Hydrocyclones at Weir Minerals, said: “Our Cavex 1 design set an industry benchmark over two decades ago with its unique 360° laminar spiral inlet geometry, which significantly reduced turbulence. This design was so successful and desired by the market that it was widely replicated by competitors.

“Following years of research, development and trials, we have improved upon this design with the creation of LIG+™ inlet and chamber design. This unique design produces a more stabilised flow pattern, further reduces turbulences and friction throughout the hydrocyclone and provides up to 30% additional capacity.”

The advanced LIG+ design (patent pending) enables the Cavex 2 hydrocyclones to classify up to 30% more feed slurry, while occupying the same footprint as competitor hydrocyclones, according to Weir. This allows operators to achieve more throughput with fewer operating hydrocyclones, reducing the upfront capital expenditure.

The new design has taken into consideration the shape and angle of the hydrocyclone to ensure particles report to the correct stream, Weir says. This reduces recirculation and misclassification, further improving separation efficiency.

“Cavex 2 allows our customers to do more,” Switzer says. “A more sustainable circuit, with lower energy and water requirements. Expand the capacity of their existing circuits, without increasing the footprint of the cyclones or clusters. It’s the kind of generational engineering leap that will change the way circuits are designed for decades to come.”

Cavex 2 takes advantage of Weir Minerals’ Synertrex® IIoT technology, which enhances the overall performance of the hydrocyclone. Armed with this technology, operators are automatically alerted to roping or blockage conditions ahead of time, ensuring the hydrocyclone runs under the most optimal operating conditions.

“To minimise the amount of bypass that is produced in any hydrocyclone, it is favourable for it to operate in the semi-roping condition,” Switzer said. “This is often difficult to do continuously because any upset in the hydrocyclone’s feed conditions could move it into the roping condition, but, with Synertrex, this balancing act can be closely managed.”

Cavex 2 hydrocyclones can be customised to suit almost any application, according to Weir, with a variety of spigots, vortex finders and liners. Liners are available in a range of material options, including Weir Minerals’ proprietary R55® rubber compound or Linatex® premium rubber, both of which have been proven to outlast competitors elastomers in similar applications, Weir says. Liners can be replaced via a ‘snap-in’ system requiring zero adhesive, while smaller models (400CVD and below) are available with moulded fibreglass housings, the company says.

Switzer concluded: “Every stage of the Cavex 2’s design has been guided by the needs of our customers. As a consequence, it has been tested in multiple mining applications throughout the globe. These tests revealed outstanding results of up to 30% additional capacity.

“Decreasing ore grades and increasing need to reduce both water and energy usage have created the need for a low maintenance, highly efficient hydrocyclone, which can be readily retrofitted into existing circuits to increase throughput and maximise returns.

“I can’t wait for our customers to see what this new range is capable of.”

Weir Minerals offers productivity, safety and throughput improvements with Synertrex

Weir Minerals has announced the launch of its Synertrex® platform, an advanced Industrial Internet of Things (IIoT) technology, which, it says, is set to transform the mining industry.

Delivering an advanced level of understanding, it allows operators to monitor every aspect of their equipment’s operation, prevent problems and increase throughput, according to Weir.

It uses network connectivity to capture equipment data and relay it to service centres, service technicians, their customers and Weir’s design centres for trend monitoring, proactive components supply and product improvement.

Ricardo Garib, Minerals Division President, said: “We believe our Synertrex platform will have a significant impact on the mining industry, transforming customer operations through improved productivity and safety.”

The company worked with technology market leaders Microsoft and Dell to develop “sophisticated predictive software and hardware” robust enough to operate in extreme conditions across the globe, he added.

IIoT is a network of equipment that connects to the internet and shares data that can be converted into unique insights. Demand for IIoT-enabled products is growing rapidly, particularly in the mining industry where it is being used in a number of areas including analytics, machine learning, and robotics.

“Synertrex is a cutting edge IIoT platform which harnesses the latest digital technology to transform productivity, foresee risk and enhance performance,” Weir said.

Using cloud computing, it involves placing smart sensors on an array of Weir Minerals’ products to gather critical operating data for advanced analysis. The data is transformed into powerful insights relayed to the customer through a digital interface.

“It can identify problems before they occur, reducing downtime, and optimise equipment performance across an entire circuit,” Weir said.

“Remote management allows for simplified maintenance. Wear and tear can be easily monitored, and trouble spots detected before they escalate into major issues. Whether it’s a drive system, structural or lubrication issues, Synertrex provides the tools to keep mining equipment at its most profitable.”

Through the platform, customers have detailed real-time insight into how equipment is performing, and machines will be able to learn over time, according to Weir.

Information is displayed on an easy to understand dashboard, which can be accessed via any device or integrated into existing operational systems. It will convey real-time, fact-based insights into machine performance and health, remaining useful life and other crucial indicators.

Fred Bradner, Vice President of Global Strategy, Sales and Marketing, said: “This platform will redefine field service standards and lead to greater performance, reliability and ultimately return on investment.”

At this stage, the platform can be paired with Warman® pumps, Cavex® hydrocyclones, GEHO® PD pumps, Enduron® HPGR, Enduron® screens and Enduron® crushers; however Weir has plans to expand the range of compatible products.

Customers with existing Weir products who wish to enable Synertrex will be able to retrofit sensors to equipment.

John McNulty, Vice President of Global Engineering and Technology, said: “This technology is backed by our 147 years of experience and unrivalled service support. Our team travel to the customers’ site to install the sensors, connect to the cloud and provide training to ensure they fully understand how the Synertrex platform works and what it can do.

“The data gathered from Synertrex combined with our in-depth product knowledge, provides unique insights on performance that only the OEM can deliver. Our extensive service network can quickly act on the outputs from Synertrex to provide unrivalled on-site support to our customers.”

Weir sees strong demand for brownfield mine solutions in H1 results

Weir Minerals clocked a solid performance in the first half of 2018 and was ably supported by strong demand for new equipment and aftermarket services from its Minerals division.

The company’s orders from continuing operations (minus its Flow Control division) were up 20% year-on-year in the six month period at £1.17 billion, while operating profit jumped 38% to £160 million.

Minerals orders increased 12% to £728 million, with original equipment orders up 9% (£222 million) and aftermarket orders up 14% (£728 million). Operating profit within the division rose 13% to £112 million.

While its Minerals division performed well, its Oil & Gas division topped it with a 35% year-on-year order jump to £438 million as North American upstream oil and gas markets grew strongly.

Weir said: “Activity in mining markets continued to grow strongly as customers ramped up production to maximise the benefits of supportive commodity prices. Demand was particularly good for brownfield solutions that help debottleneck, increase throughput and reduce downtime of existing mines.”

The pipeline of new projects continued to increase driven by good long-term fundamentals for commodities such as copper, gold and lithium, the company said.

“Customers remained disciplined about committing to new greenfield developments, although a small number of projects received final approval.”

Weir said its early investment in deploying more engineers to customer sites to help miners improve productivity had continued to support strong order growth in the first six months of the year with sales from integrated solutions, which leverage the division’s portfolio of premium products, delivering around £50 million in additional orders. Weir noted engineers completed 374 site audits in the period.

“The division also continued to grow market share through its successful trials programme that sees it go head to head with competitor products to demonstrate the superior performance of Weir equipment,” the company said.

The first half also saw the opening of additional service centres in Zambia, Chile and Peru to further extend Weir’s service network.

Weir’s technology programmes focused on continuous improvement in the division’s core products while also developing its Synertrex® IoT solution. Weir said full commercialisation of this technology in mining markets was planned for the second half of the year.

Synertrex uses network connectivity to capture equipment data and relay it to service centres, service technicians, their customers and Weir’s design centres for trend monitoring, proactive components supply and product improvement.

After the end of the quarter, Weir completed the acquisition of Esco Corp in a deal that came with an enterprise value of $1.29 billion.
