PPE for Machinery with Hardox Wearparts

hardoximg_298f1928Mining is one of the toughest industrial sectors in Australia: It’s tough on the people, and it’s tough on the gear.

There’s been a lot of progress made in protecting people over the past ten years, but what about protecting the machinery that’s responsible for making every dollar faster?

Whether you’re talking about a mobile or stationary plant, there’s a range of machinery parts that need protection from wear and tear caused by minerals and ores.

Hardox Wearparts produce and supply a wide range of custom manufactured wear parts for a range of machinery utilised across the mining and quarrying industries including; wear strips, cutting edges and skins for excavator buckets, blades for dozers and graders, and liners for dump truck trays through to liners, bars, screens and skirts for chutes, feeders and crushers.

The key to the quality of Hardox Wearparts is the selection and use of the most appropriate grades from SSAB’s wide range of Hardox steels, combined with leading knowledge of wear part manufacturing methods optimised to retain the desired properties of the steel in the end products.

Ian Cornfoot, Wear Service Manager for Hardox Wearparts in Oceania knows all too well the problems associated with machinery wear and how to prevent them.

“It’s about the balancing of materials that can cope with both impact and abrasive wear,” he says.

“You can get very hard products that are good at combatting abrasive wear, but are generally quite brittle and can crack under impact. With expensive production losses resulting from unplanned downtime, this is something that needs to be avoided.

“It’s the same the other way, you can get softer materials that are very good at handling impact but abrasives cause them to wear very quickly, resulting in shorter maintenance intervals.”

That’s why Hardox Wearparts makes wear products that strike the right balance for dealing with both impact and sliding abrasion scenarios.

Hardox Wearparts work with their customers to understand the needs of the wear parts based on production and maintenance schedule needs.

“For mobile plants there are clear advantages in cost savings from weight reductions which can translate into reduced cycle times and increased productivity, but for stationary structures we can generate cost savings through careful material selection processes which caters to specific maintenance schedules, machinery and mineral needs,” Ian says.

“There is an ongoing focus on extended maintenance intervals and streamlined maintenance strategies across the Mining sector. Ideal maintenance schedules should have most parts lasting about the same amount of time; you don’t want a range of maintenance schedules for different wear parts on the one machine, and you don’t want to be wasting money changing out parts that have life left in them but may not achieve another full maintenance interval.

Ian says Hardox Wearparts are concerned with getting the best value out of their parts for the customer, which is why the company uses proprietary computer software to review different wear scenarios in your machinery, incorporating minerals analysis relative to your particular mine site or quarry, and providing estimations on the relative life of different materials.

“For example, if you’re currently using mild steel, or a 450 Brinell wear plate, then under the same conditions we can estimate what gains in wear life you may be able to achieve with different material grades. The software can indicate to us where the maximum benefit of using harder wearing plate will be: there may be a huge benefit in going from 450 to 550, but under your particular wear regime an increase to a 600 Brinell material could be negligible.”

This can help in the selection of the most appropriate materials to achieve increased maintenance intervals, or to enable the selection of thinner wear parts, resulting in a lighter machine operating on the same maintenance schedule.

“The hardest materials are not always the best: we want to be economical so that our customers get the best advantage possible from our products.”

In this fashion, the software helps to make estimates of the minimum product required to get the best economy out of Hardox products, keeping weight and material costs down.

The Hardox steel as used by Hardox Wearparts is produced exclusively by SSAB in Sweden and the USA, with the entire steelmaking process being tightly controlled to minimise impurities, and using very low levels of alloying elements in order to optimise the materials for welding. The hardness levels of the steels are achieved through a closely controlled roller quenching process and subsequent heat treatments designed to achieve consistency and through hardness.

Hardox Wearparts is a leading manufacturer of wear parts and wear services around the world, with more than 150 centres and operating in more than 55 countries. Locally, Hardox Wearparts have centres in Western Australia, Queensland, Victoria, Tasmania and New Zealand.

Keech develops self sharpening bucket teeth

KeesharpKeech Australia has introduced a new innovation designed to assist construction and mining operators extend the working life of their loader buckets, and boost productivity by reducing costs and downtime.

Keesharp, Keech’s new product innovation is a bucket tooth designed to get sharper with use. According to Keech Australia Marketing Manager Brad Clark, the bucket tooth offers market-leading longevity and also extends the operational life of the bucket. He explains that Keesharp adaptor and bucket tooth systems increase nose strength and integrity, while the specialised design of the tooth profile increases the sharpness of the tooth with use, boosting efficiency.

As it gets sharper over time, Keesharp improves bucket penetration in even the most challenging conditions. Since Keesharp enables easy changeover with a one-pin-fits-all design, productivity is further enhanced with better machine availability and reduced downtime. Keesharp is recommended for applications ranging from underground production and development to open pit mining and digging as well as construction and earthmoving requirements.

Key features and benefits of Keesharp self sharpening bucket teeth include hammerless system designed with a pin on either side of the tooth for a more balanced locking system; tooth and adapter absorbing the force of digging to keep the pins free of pressure for optimum performance; quick and easy replacement of teeth with a single pin size across the range allowing simple and safe tooth changeover; and suitable for machine sizes from 20 to 350 tonnes.

Steel production slumped worldwide in 2015

steel-Industry-imprvGlobal steel output fell last year, the first time this has happened since 2009, according to figures from the World Steel Association released this week.

The report from the WSA states production was down in every region besides Oceania.

The USA’s production was down 10.5 per cent to 78.9 million tonnes, Japan down 5 per cent to 105 million tonnes, and the EU down 1.8 per cent to 166.2 million tonnes.

A standout was India, which managed to up its production 2.6 per cent to 89.6 million tonnes.

Reuters notes that world leader China, which accounts for nearly half of global output of crude steel, cut its annual output for the first time in three decades. This fell 2.3 per cent to 803.8 million million tonnes.

“Many mills including (in) China are pulling production offline in an attempt to support prices — and it is working,” Chris Houlden, research manager at consultancy CRU, told Reuters.

“However, any reversal of production cutbacks in response to price rises will again place steel producers’ margins under extreme pressure.”

In April last year, a leading Australian economist (and former ambassador to China) Ross Garnaut tipped China’s steelmaking output to fall 25 per cent to 2030, reaching around 600 million tonnes.

China’s Zoomlion (中联重科)Makes Unsolicited Bid to Acquire Terex

Terex Corp. has received an unsolicited, non-binding acquisition proposal from China’s Zoomlion Heavy Industry Science and Technology Co. to acquire all of the outstanding shares of Terex for $30.00 in cash. The proposal is conditioned on, among other things, receipt of U.S. and Chinese regulatory approval and Zoomlion shareholder approval.

Terex announced last August that it had entered into a Business Combination Agreement with Finland-based Konecranes Plc providing for a combination of Terex and Konecranes. The Terex board of directors has not changed its recommendation of the proposed combination with Konecranes.

Terex acknowledged it has entered into a confidentiality agreement with Zoomlion and is in discussions with Zoomlion regarding the proposal. Consistent with its fiduciary duties, the Terex board of directors, in consultation with its legal and financial advisors, is carefully reviewing the Zoomlion proposal to determine the course of action that it believes is in the best interests of Terex shareholders. Terex will have no further comment until the board has completed its review.

Credit Suisse Securities (USA) LLC and Moelis & Company are serving as financial advisors to Terex and Fried Frank Harris Shriver & Jacobson LLP, Bryan Cave LLP and Avance Attorneys Ltd are acting as legal counsel to Terex.

Zoomlion is believed to be China’s second largest construction equipment manufacturer, valued at about $4.4 billion.

Terex stock, which closed Friday at $15.49, has jumped 37.1 percent to $21.24 as of 2 p.m. EST Jan. 26.

Another manganese operator enters administration

shawThe third Australian manganese operator in two months has closed operations as the commodity price falls.

Shaw River, owner of the Otjozondu manganese project in Namibia, has entered voluntary administration “as a consequence of low manganese ore prices”, which halved in 2015.

It follows fellow Australian companies OM Holdings – which closed its Bootu Creek mine in December – and Consolidated Minerals – which shut down its Woodie Woodie mine last week – in shuttering its operations.

Shaw River is placing “itself in a trading halt and then in voluntary suspension while the company pursued a restructuring of debt as a precondition of a fund raising to be initiated in the New Year,” it said in a company statement.

It explained that while it still has a credit line with its major shareholder available, “beyond an initial loan amount all additional drawdowns were at the discretion of the lender….late in the year, the lender informed the directors that its capacity to advance further funds was limited.”

Shaw River carried out an SPP last month to reduce debt obligations, however it failed to raise enough from its shareholders.

“Unfortunately the company has not received any assurance from a third part that is it possible to raise funds in the short term for a company such as Shaw River that operates in the resources sector or more particularly in the manganese sector, particularly while the stock markets are volatile.”

Shaw stated it has already ‘aggressively’ pared back operating costs “t o levels not previously thought possible”, however the fact that manganese ore has fallen to levels not seen since 2003 negated its efforts.

“These low ore prices are having consequences,” the miner said.

“Within the manganese ore market, production of internationally traded ore has been severely pruned with full and partial closures of mines in many countries including notably South Africa and Australia, and the closures announced continue at least through January.”

However despite the wide scale slaughter manganese operators are facing , Shaw River managing director Peter Cunningham does see a future for the commodity.

“These cutbacks are resulting in shortages of some grades of manganese ore,” he said.

“Spot prices in China are showing early signs of recovery.

“However, demand in China has been constrained in advance of Chinese New Year, and so stocks of ore in China ports have yet to decline significantly. Demand is expected to improve after Chinese New Year, and this improvement should provide opportunity for restructuring of Shaw River and its subsidiaries.”

Nearly 400 jobs go at Woodie Woodie mine

Approximately 380 workers jobs have been cut as Consolidated Minerals place the Woodie Woodie mine in care and maintenance.

Workers were informed of the decision late last week, which will affect the 330 FTE and 50 contractors on site, according to the ABC.

The miner blamed falling manganese prices as the driver behind the operation’s closure.

“Despite the relentless efforts and substantial achievements of our leadership group, our employees and our suppliers to transform Woodie Woodie into a globally competitive operation which we can all be proud of, the price for manganese ore is now so low that continuing to operate is no longer an option,” Consolidated Minerals managing director Paul Muller said.

Woodie Woodie is the second Australian manganese mine to close in as many months, after OM Holdings placed its Bootu Creek manganese mine – in the Northern Territory – into care and maintenance in December.

That same month South32 announced its plans to lay off more than 400 workers from its manganese operations in South Africa.

Consmin will keep approximately 30 workers on staff, 15 onsite and 15 at its head office in Perth, to restart operations once the commodity picks up again.

“Fourth industrial revolution” to increase inequality, predicts UBS report

A research paper by UBS has predicted that a combination of automation and connectivity will see the competitive advantage of low labour cost countries shrink, but also lead to rising inequality.

Released at the 2016 Davos World Economic Forum, the research argues that the effect of the “Fourth Industrial Revolution” will have the greatest effect on developing markets.

It describes the revolution as following steam, electricity and electronics, and involving a joining of “extreme automation” and “extreme connectivity”.

Low-skilled jobs will be affected, and middle class roles will also be increasingly automated out of existence. “Middle skill” employees would feel the “greatest disruption”.

Inequality increases not just between developed and developing and emerging countries,” explained UBS chairman Alex Weber, according to Sputnik News.

It’s also within our society. It will have an impact not only between the rich and the poor but also the young and the old.

Tech Republic notes that an increase in aggregate worldwide unemployment, however, is not modelled in the research, with workforce productivity increasing and new jobs being created.

Also anticipated is a reshoring of manufacturing to higher-wage countries, driven by robotics, automation and 3D printing.

BGC win iron ore contract

koolnobBGC Contracting has won a five year contract extension with Cliffs Natural Resources.

The $520 million contract will see BGC Contracting extend their operations at the Koolyanobbing iron ore project past the original end date of 2017 to 2022.

It has been on site since 2004, initially providing off-road haulage, which was expanded to include mining operations in 2007.

Under the contract BGC will continue to provide mining services, in including drilling, blasting, loading, haulage, dumping, crushing, screening, and train load-outs.

Greg Heylen, BGC Contracting’s CEO, explained the extension came on the back of the contractor’s “ability to meet Cliffs’ safety and production targets during a challenging period for iron ore producers”.

“This has been a tough period as the iron ore price has fallen, and I believe that by maintaining strong relationships with Cliffs at all levels of our organisation, we have helped them succeed at Koolyanobbing in what has been a difficult market for all iron ore miners,” Heylen said.

The project is located in WA’s Yilgarn region, 400 kilometres north east of Perth.

China to shut down more than 1000 mines

China has announced it will shut more than 1000 mines across four provinces in the country’s north and south.

The country currently has approximately 9620 legal coal mines.

It comes after the nation announced it will not approve any new coal mines over the next three years.

The move is part of a bid to dramaticallyreduce existing coal stockpiles.

The latest coal mines to be shut are in the Yunnan, Jiangxi and Guizhou provinces in the south, and the Heilongjian province in the north, according to China Daily.

China’s deputy director for the State Administration of Work Safety, Huang Yuzhi, explained it will reach its production and stockpile target by slashing the number of smaller operating mines.

“More than 1300 coal mines were closed last year, and small coal mines with a scale of annual production of less than 300,000 tons that had major accidents will be gradually closed this year, as well as those mines that are operating illegally,” Huang said.

Oil and gas, contractors, and diamonds Australia’s fastest declining industries

A new IBISWorld report has highlighted petroleum refining, contract mining, and diamond mining as the country’s fastest declining industries in 2016.

Petroleum refining is slated to shrink 16.7 per cent this year, with industry revenue to decline at compound annual rate of 7.7 per cent over the five years through 2015-16 to sit at $19.1 billion.

In little surprise, as the mining industry declines contractor and support services are predicted to decline in line with the sector and as operators look to in-house production rather than outsourcing services.

The industry is highly dependent on trends in mining activity, particularly black coal and iron ore mining activity, as these are Australia’s largest resources in terms of both volume and value,” according to IBISWorld senior industry analyst Spencer Little.

As commodity prices have fallen, many mining firms have ceased expansion and exploration projects, and instead shifted their focus to production.

“This has been to the detriment of contract miners in the industry, as many services that were previously contracted out have been brought back in house,” Little said.

IBISWorld forecasts a 6.3 per cent decline in contract mining, engineering, and services companies revenue down to $11.2 billion.

This follows the sharp 14 per cent decline in revenues recorded last year.

Diamond mining is also slated to fall, after a short rally in 2014, when it saw a 24 per cent growth in revenues.

Instead the industry is predicted to experience an annual compound decline of 4 per cent over the five years through 2015-26, to fall to $380.1 million.

“The industry’s performance has been volatile over the past five years, due to fluctuating production volumes and prices; a significant drop in revenue in 2013-14, and another expected fall in revenue in 2015-16 are expected to underpin the industry’s poor performance over the period, “ IBISWorld stated.

This fall, while in line with the general decline in mining, has been precipitated by Australia oversupplying the market.

“As a result, the industry is heavily export-oriented and industry players depend on global demand for diamonds. According to the Department of Industry, Innovation and Science, in 2013-14 export volumes of Australian diamonds dropped from 12.2 million carats to 10.4 million carats,” IBISWorld added.

“Industry operators also face strong competition from imports, which account for a large proportion of total domestic demand,” Little said.

The exit of Kimberley Diamonds, previously a major industry player, is expected to negatively affect the industry’s performance in 2015-16.

In July 2015, Kimberley Diamonds announced that it had ceased its local diamond mining operations at its Ellendale site and entered into voluntary administration.

This exit is expected to cause a major dip in diamond production volumes and contribute to a 13.3% decline in industry revenue in 2015-16.

There has also been additional shakeup in the diamond industry, with the announcement today Rio Tinto’s head of diamonds and minerals, Jean-Marc Lieberherr, has stepped down, to be replaced by the current head of salt and uranium, Simon Trott.
