A $100 million “global first” innovation precinct is coming to Sydney

Malcolm-Turnbull-china-640x332 Australia is set to get a “global first” $100 million innovation precinct that will foster innovation, support local startups and drive commercialisation.

Malcolm Turnbull announced the partnership between the Chinese Ministry of Science and Technology and the University of New South Wales during his first trip to China as prime minister.

The deal will see a $100 million Torch Precinct established on the university’s campus.

The Torch precincts have been operating in China for nearly 20 years and now generate 7% of the country’s GDP.

The UNSW precinct, the first of its kind outside of China, could contribute $1 billion to Australia’s GDP in its first ten years, according to a Deloitte study.

UNSW president Ian Jacobs says the precinct is a “global first”.

“[It] has the potential to reset the Australia-China bilateral relationship and boost the nation’s innovation system,” Jacobs says in a statement.

“This is about future-proofing our national competitiveness by strategically positioning Australia as China becomes the world’s largest investor in R&D and the 21st century’s science and technology superpower.

“The Torch partnership is an important milestone in the further development of Sydney as Australia’s global innovation city.”

A group of eight Chinese companies have already committed $30 million to the program, with an aim to build investment to $100 million.

The industry partners will establish incubator spaces on the Kensington campus before the precinct is constructed by 2025.

During his trip to China, Turnbull also officially unveiled the startup landing pad in Shanghai, joining other locations in Silicon Valley and Tel Aviv.

ABB survey shows majority of utilities see IoT as key to asset management

iot A global survey of executives at leading utility companies by power and automation technology specialist ABB has revealed the increased importance of integrating information technology (IT) and operational technology (OT) for effective asset management.

According to the study, which covered over 200 executives at leading electricity, gas and water utilities, IT-OT integration is considered a key component of any effective asset management strategy. While 80 per cent of the respondents believe IT-OT integration is valuable for asset management, 58 per cent either have or are planning to have, a strategy leveraging the Internet of Things (IoT) for asset management. About 55 per cent of those surveyed reported that the importance of asset management had increased over the past 12 months.

The internet allows things, services and people to be interconnected, improving data analysis, boosting productivity, enhancing reliability, saving energy and costs, and generating new revenue opportunities through innovative business models. The industrial internet and cloud services also offer the benefit of bringing world-class analytics within reach of smaller production facilities. For over a decade ABB has been developing and enhancing process control systems, communication solutions, sensors and software that support the concept of the Internet of Things, Services and People (IoTSP).

Massimo Danieli, Managing Director of the Grid Automation business unit within the company’s Power Grids division observes that utilities, now more than ever, see the need to bring together once disparate technologies and systems to better understand their increasingly complex asset base and share those insights with people across the organisation, in order to improve planning, productivity and safety. Commenting that it was very much in line with ABB’s focus on IoTSP as part of their Next Level strategy, he added that the company’s comprehensive portfolio put them in an ideal position to support their customers in integrating the worlds of information and operational technology.

Respondents to the survey see numerous benefits in the IT-OT integration. On a scale of 1-5, they ranked better long-term planning (4.86) as the highest priority, followed by increased staff productivity (4.43), improved safety (3.98) and better use of capital (3.68).

The study ‘Bridging IT and OT for the Connected Asset Lifecycle Management Era’ was conducted in collaboration with Microsoft Corp. and market research firm Zpryme.

PPE for Machinery with Hardox Wearparts

hardoximg_298f1928 Mining 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

Keesharp Keech 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.

A silver liner-ing at a copper mine

Lining-TrellexPolycer Despite having the world’s sixth largest copper deposit, Compania Minera Dona Ines de Collahuasi is facing the same issues miners are facing the world over: that of ensuring future productivity and overall viability.

As part of this process the operator instituted a new ‘preventive improvement process’, with the objective of detecting potential problems in advance to maximise performance and equipment availability.

Compania Minera Dona Ines de Collahuasi contacted Metso as part of this improvement effort to manufacture and mount of a new chute with four outputs for a 11’ by 11’ semi-autonomous grinding (SAG) mill.

“Pleased with the good results and the fact that all deadlines were met without any accidents, Compania Minera Dona Ines de Collahuasi decided to order three more chutes for the pebble stage,” Metso said.

“As a company we look for suppliers who can provide an integrated service that includes engineering, manufacturing, as well as assembly,” Manuel Vera, Compania Minera Dona Ines de Collahuasi’s asset management and reliability manager, said.

“Metso’s unique ability to offer an integrated solution was one of the key factors in the company’s decision to collaborate with them.”

Metso’s integrated approach consisted of several phases, beginning with the gathering of field data about the existing chutes in operation.

Desarrollo-Chute-Collahuasi-2015-2 It turned out that the SAG mills needed improvement and that a liner change out was relatively challenging.

Additionally, the chutes were unable to absorb the full impact of the falling ore.

“All this added up to an insufficient flow, as evidenced by the large amounts of ore in the passageways and around the transfer chute,” Metso said.

“This excess material created premature wear in the conveyor belt and its support structure.”

These findings were passed on to the design, where they resulted in proposed improvements that were then validated through HFS simulations.

The design improvements aimed at reducing downtimes for liner change outs, increasing overall availability as less time is needed to schedule maintenance.

In addition, the new design included chute door systems for inspection and maintenance.

The integrated solution also included carrying out the actual liner change out and the assembly of the new chutes, as well as a follow-up on the performance of the liners and a continuous improvement plan for the transfer chutes.

Metso installed its extended wear life Trellex Poly-Cer solution, a modular system of ceramics and rubber, which provides increase resistance to strong abrasives – even with high tonnages at high speeds.

The new design of the chute liners makes maintenance easier by streamlining the change out of the anti-wear plates within each structure.

“Thanks to Trellex Poly-Cer’s greater resistance, it is typically up to ten times more wear-resistant than its steel counterpart,” Metso said.

The plates consist of ceramics (1400 HB) and rubber, providing both wear resistance and elasticity to absorb impacts.

As a result of these new designs, the service life of the chutes at Compania Minera Dona Ines de Collahuasi mine has increased.

“The original design required maintenance every 20 days or so,” Vera said.

“But now the interval is longer, and we know that optimisation of this can continue.”
