MATERIALS PROCESSING NEWS IN BRIEF

Metso recognised Metso has been presented with an award by Freeport-McMoRan Inc. for the long-term partnership between both companies. “Your long-time support of Freeport-McMoRan has been a cornerstone of our success. Most recently, your highly motivated team has partnered with us as we weather the difficult cycle that brought copper prices to near six-year lows. Thanks to this team effort, both our companies have worked to reduce costs, gain efficiencies and remain competitive. I am confident in the long-term future of commodities and our industry. We look forward to further strengthening our partnership and moving ahead together,” says Richard C Adkerson, president and CEO of Freeport-McMoRan. CDE’s research buy-in CDE Global recently participated in the first meeting of the EU-funded RE4 Project in Brindisi, Italy. Over the next three-and- a-half years following the first landmark gathering on September 15, CDE shall contribute to this group to develop new technologies to increase the reuse and recycling of construction and demolition waste material in energy efficient prefab- ricated elements for building refurbish- ment and construction. “To be involved in the first Horizon 2020 funded research project in this area is an exciting prospect and a great oppor- tunity to make significant advancements in reducing the environmental impact of construction and demolition activities,” said Sean Kerr CDE representative, the Northern Ireland firm’s head of engineer- ing, speaking about the project. Terex AggreScalp to boost quarries’ bottom line Terex Washing Systems (TWS) has launched its new Terex AggreScalp scalp- ing unit and new Finesmaster UltraFines recovery system, both said to boost any quarry operation’s bottom line. The Terex AggreScalp is a versatile, high-perfor- mance heavy-duty electric screening ma- chine that has the flexibility to operate as a two-way or three-way split screener. The aggressive screen can accept media including bofor bars, finger screens, woven mesh and 3D punch plates, which allows it to be used across a wide variety of applications. With on-board hydraulic folding product conveyors, hydraulic screen angle adjustment and single lift set-up, it is easy to transport and to set up. The AggreScalp can work in conjunc- tion with the Terex AggreSand range by providing a consistent feed material even in difficult applications. b

Weir Group forges ahead with foundry investment

Since the 2013 acquisition, Weir HBF is now ISO9001, OHSAS18001 and ISO1400 accredited.

Weir Group’s investment into itsWeir Heavy Bay Foundry (HBF) continues at pace, and is set to position the operation as a best cost producer of quality castings. The recent commissioning of an advanced secondary sand plant at Weir HBF will allow the Port Elizabeth foundry to reduce manufacturing costs, further enhance the quality of its castings and mitigate the impacts of the operation on the environment. Grant Ramsden, operations director at Weir Minerals Africa, says the new sand plant deploys magnetic separation technology to extract chromite sand added to furan sand during the moulding process. The plant also scrubs the resin from the sand by a process of attrition. The recovered furan sand can now be reused, resulting in significant savings in sand disposal costs, resin costs and the purchasing of new sand. “In addition, Weir HBF will be able to improve the efficiencies of its casting processes by reducing ‘sand Haver & Boecker, an equipment manufacturer and solutions provider in aggregates and mining applications, has introduced its Tyler brand of hooked engineered screen media as a solution to the problem of expensive deck conversions. Tensioned screen media can be used on a cambered deck, eliminating the need for a deck conversion when switching from woven wire to polyurethane screen media. The media includes products such as Ty-Max and Ty-Wire. “Hooked screen media allows operations to easily switch from woven wire to modular polyurethane products without the expense of a deck conversion,” the company says. Retrofitting a machine from a cambered deck to a flat deck can cost as much as US$15 000 per deck. Tyler’s tensioned screen media is used on a cambered deck to eliminate the need for that conversion. This also allows operators to test the media on a vibrating screen with no additional cost or commitment. Another benefit is that Ty-Max and Ty-Wire can be blended with woven wire or

burn-on’ caused by excess chromite sand in the furan sand,” says Ramsden. The secondary sand plant incorporates German proprietary chromite separation technology, and state-of-the-art program- mable logic controllers. In line with lean manufacturing principles, the plant only runs when there is a demand for sand. It was installed and commissioned using Weir engineering expertise. The lion’s share of the overall investment has gone into improving safety and productivity of workers at the operation. A sound example of this is the seven new fettling booths that have all been equipped with dust extraction systems. “Equipped with state-of-the-art equipment and its strategic location close to the deep water Port of Ngqura, there is no reason why this operation will not be able to contribute to Weir Minerals Africa seizing a larger share of the niche one ton to 17 t castings market,” says Ramsden. b self-cleaning screens on cambered decks. In many applications, operators are looking for more wear life on the feed end of the screen. This can be accomplished by installing a section of Ty-Max at the feed end. Ty-Wire can be used in the middle of the deck, for example, where basic screening takes place to give operators the ideal combination of wear life and open area. Using woven wire or self-cleaning screens at the discharge end will provide maximum open area at the end of the deck. The polyurethane screen media is manufactured out of Tyrethane, Haver & Boecker’s signature blend of polyurethane. Chemists developed Tyrethane to offer the best combination of open area and wear life for both wet and dry applications. Tyrethane is poured open cast, resulting in 1,5 to two times longer wear life than comparable injection-moulded products. In addition, open cast polyurethane permanently hardens when cured to maintain its chemical properties, so it resists wear and tear. b
