Metso is to install high-performance crushing and material handling equipment underground at the De Beers Group’s Venetia diamond mine, in South Africa, as part of an order booked in the September quarter.

In the throes of a transition from open-pit mining to underground operations, Venetia is reported to produce around 4 Mct/y, making it one of South Africa’s biggest diamond mines.

In 2013, an underground extension project commenced with plans to start producing carats in 2022, climbing to full production in 2025 and extending the mine life to 2046.

Metso said Venetia approached Metso to deliver two primary jaw crushers and a number of feeders. All the equipment will be installed underground, which is a very challenging installation, especially given the shaft constraints (dimensions) and weight limitations for transportation underground, the company added.

Venetia decided on Metso’s Nordberg® C Series™ jaw crusher range as the pinned and bolted design of the crusher allowed for the extensive disassembly, Metso said. “This enhances ease of transportation and installation, especially where there are critical space constraints such as an underground installation – as is the case with this project.”

The Metso apron feeders, meanwhile, are used for extracting or feeding ores that are wet, sticky, dry or even frozen.

Minprovise keeps crushing on track at Hope Downs 1 iron ore mine

Minprovise says it has completed a jaw crusher replacement project at Rio Tinto and Hancock Prospecting’s jointly owned Hope Downs 1 iron ore mine site in the Pilbara of Western Australia.

The crusher in question, a Metso Nordberg C160, is Hope Downs’ primary crusher. Minprovise was selected for this project due to the positive references it has previously received carrying out similar work in the field, the mineral processing equipment and site services provider said.

The crusher replacement was the second such project completed in the last year by Minprovise, the first being undertaken at the West Angelas mine site (part of the Rio-majority owned Robe River joint venture), located in Newman, in late 2018.

Hope Downs 1 is part of the Hope Downs joint venture. The Hope Downs 1 and 4 deposits produced 46.9 Mt of iron ore in 2017, according to Rio.

“The large-scale site maintenance project required careful quality control and site safety management in the lead up to, and during, the crusher replacement,” Minprovise said. The team were required to safely and efficiently remove the old jaw crusher model and replace it with the newer C160 model in its already established and confined structure, according to the company.

“Minprovise’s end-to-end business model and internal manufacture and fabrication capabilities meant that the team were also able to fabricate the appropriate and tailormade transport frames, jigs and chute covers for the optimised safety of the project,” it said.

To complete the lift, the company used a 500 t crane to safely manoeuvre the 78 t crusher mainframe into place.

As the sole provider of the install process, Minprovise was required to coordinate between the client, the transport agency, the crane provider and the crusher manufacturer to ensure a smooth and time efficient process, it said. “Minprovise’s phase of the replacement project was completed in the originally quoted and designated amount of time, with no hiccups or costly time-delays.”

The fabrication and install of the crushers casting plates to take the full impact of the crushers vibrations was also undertaken by Minprovise employees.

Throughout the entire process – which included concrete cutting and jackhammering of the support base, removal and replacement of the casting plates, re-grouting of the new base and plates and heavy lift and install of the crusher – zero safety incidents or minor injuries were reported, according to the company.

Metso says it is expanding its crusher wear part offering by launching a new range of OEM crusher liners.

Available for selected markets from September, the new Metso O-Series offers the right balance between performance, affordability and reliability, the company said.

Olli Heinonen, Head of O-Series development at Metso, said: “The Metso O-Series offers a value-priced alternative that is ideal when you need to focus on optimising daily operations, while our premium crusher wears range ensures additional durability, performance and maximum return on investment.”

The Metso O-Series range is now available for Metso Nordberg® HP Series™ and GP Series™ cone crushers as well as C Series™ jaw crushers, Metso said. In the first phase, the new range will be sold through Metso sales offices, and the accredited Metso distributors in China, Mexico, Central America, and Asia Pacific.

Heinonen concluded: “The Metso O-Series was created in close cooperation and dialogue with our customers to especially meet the business requirements in rapidly developing markets. We are excited about this new range and the new opportunities to help our customers get better control of their operations without compromising on quality. Going forward, we’re looking into bringing further crusher models to the range as well as introducing it to additional markets.”

Metso celebrates 10,000th Nordberg HP cone crusher sale

Metso says it has reached the significant milestone of 10,000 Nordberg® HP cone crushers sold globally.

The most popular modern cone crusher in the world, the company says, the HP Series™ celebrates its 30th anniversary this year.

The 10,000th HP cone crusher unit was handed over to the French aggregates and asphalt producer and urban infrastructure development company, Eurovia, in a ceremony held today at Metso’s Mâcon facility in France.

Arto Halonen, Vice President, Aggregates Crushers at Metso, said: “The HP is undoubtedly one of Metso’s most widely used innovations. It’s a technology that has been evolving throughout the years to meet customers’ changing needs, making their operations more successful through proven performance and reliable output. That’s most likely why HP has become an industry standard for a variety of aggregates and mining applications.”

The origin of the HP Series cone crusher can be tracked back to Milwaukee, USA, in the early to mid-1980s. “The technological breakthroughs by the Nordberg research program re-defined crushing performance and provided the basis for a new type of cone crusher introduced in 1989: the Nordberg High-Performance cone crusher series, today simply known as the HP,” Metso said.

Today, HP cone crushers are engineered and manufactured in Metso’s competence centre in Mâcon, France, with manufacturing also in Brazil, China and India.

A versatile crusher, it is used in a wide range of fixed and mobile applications, varying from limestone to taconite and ballast production to manufactured sand, Metso said.

Halonen continued: “Know-how from developing the HP and from thousands and thousands of customer applications around the world has played an integral part in Metso research and development initiatives in crushing.

“This is an important milestone for Metso and we want to thank our customers for their continued confidence in us during the first 30 years of the HP’s journey and look forward to explore new development possibilities in the years to come.”
