thyssenkrupp BRINGS THE

thyssenkrupp BRINGS THE TEST LABORATORY TO THE CUSTOMER’S DOORSTEP thyssenkrupp Industrial Solutions South Africa (tkISSA) has streamlined the sample testing process with the recent development of a mobile containerised High-Pressure Grinding Roll (HPGR) test unit. By enabling customers to test samples on site, this eliminates the costs, time delays and complex logistics related to the transportation of samples for testing purposes. 8 The inspiration to create this distinctive containerised laboratory was spurred on by a customer who required the pre-crushing of uranium ore causing various dilemmas in ore processing, transportation logistics as well as handling of radioactive material. Taking all these factors into consideration, the company came up with a gamechanging idea; bring the test laboratory to the customer. The mobile laboratory consists of a semi-pilot scale HPGR fully enclosed in a 20-foot container. “The HPGR was developed in Germany, but we have adapted the design for manufacturing in South Africa,” says Gerhard Van Wyk, Process Manager: Minerals Processing at tkISSA. When installed in the container unit features a ground-breaking plug-and-play configuration; as the machine is transported as a final assembly and customers only need to supply a main power connection, it is possible to immediately start the machine for production. Depending on customers’ needs the capabilities of the containerised laboratory include the ability to run single pass tests on numerous different material types. “This would be required to determine the HPGR’s specific performance parameters,” explains Van Wyk. In addition, this versatile lab is also able to process large quantities of sample through the unit, ready for downstream processing. “In fact, with our very first unit, which we rolled out to a customer in Africa in Q2 2019, was used for the crushing of a massive 700t sample, bearing testament to the success of our locally adapted design.” This unit was subsequently returned to the original installation in thyssenkrupp’s test facility and the first test campaign since its return has already been completed. This containerised lab offers a host of benefits; the fact the machine is deployed at the rock face at the customer’s mine removes the need for sample transportation which leads to increased uptime and enhanced productivity for lowest total cost of ownership for the customer. tkISSA will also configure the machine into the customer flowsheet if required. “Not only are we responsible for the manufacture of the machine but, given the fact that it remains on the customer’s site for a relatively short period we are also responsible for operation,” notes Van Wyk. He also points out that the company will provide an additional process engineer if the customer requires specialised tests. In the event of longer durations, thyssenkrupp will train the site personnel and empower them to operate the machine themselves. thyssenkrupp has already received enquiries from America, Australia and Europe for this solution. Based on the experience gained by operating the unit, thyssenkrupp plans to develop Container Version 2.0 which will incorporate Industry 4.0 equipment as well as a wide range of upgrades. According to Van Wyk, who is Concept Designer and Project Manager, adapting the containerised lab was a solid team effort and he extends his sincere thanks to the entire team which includes Jeffrey Johns (Mechanical Engineer), Craig Harvey (Workshop Manager), Louis Nel (Workshop Apprentice), and Donald Swanepoel (Field Service Representative). “We are extremely proud of our in-house developed and manufactured containerised laboratory which sets the sample testing benchmark,” says Philipp Nellessen, thyssenkrupp Industrial Solutions CEO, Sub-Sahara Africa. “By continuously tailoring our offerings to meet customers’ needs, we look forward to further assisting them in maximising their productivity potential.” About us: The Industrial Solutions business area at thyssenkrupp is a leading partner for the engineering, construction and service of industrial plants and systems.

ROCKWELL AUTOMATION ANNOUNCED AS FOUNDING MEMBER OF ISA GLOBAL CYBERSECURITY ALLIANCE Production facilities can contain thousands of technologies from different vendors. Cybersecurity threats only need to exploit one of them to steal trade secrets, stop production or even harm workers. To better secure today’s complex and often vulnerable production operations, the ISA Global Cybersecurity Alliance recently announced Rockwell Automation as a founding member. The alliance is a coalition of industry, government agencies and others working to help secure industrial operations. Some of its objectives include: • Accelerating the expansion and use of the ISA/IEC 62443 standards • Developing a skilled and cyber-aware workforce • Optimising compliance and prevention initiatives “We need to work together as an industry, because an attack on one of us is an attack on all of us,” says Megan Samford, Director of Product Security, Rockwell Automation. “Working with partners and competitors alike, we can develop common solutions to better secure operations. And we can address issues like skills shortages that directly impact security. We also strongly encourage our customers to join us in this effort, because it’s their operations that we’re working to protect, and it’s their voices we most want to hear.” “Cybersecurity is critical to digital transformation. It’s critical not only for the protection of information and intellectual property but also for the protection of physical assets, the environment and worker safety. Our engagement with the Global Cybersecurity Alliance will be another important step in our efforts to help customers identify and mitigate risks,” explains Rockwell Automation CEO Blake Moret. ISA developed ISA/IEC 62443, the world’s only consensus-based cybersecurity standards for automation and control system applications. Rockwell Automation has earned ISA/IEC 62443-4-1 certification for its Security Development Lifecycle, which it uses to design security into the lifecycle of its products. The company also recently introduced the first industrial controller to obtain ISA/IEC 62443-4-2 certification. Companies can join the Global Cybersecurity Alliance here. About ISA The International Society of Automation (www. is a nonprofit professional association that sets the standard for those who apply engineering and technology to improve the management, safety, and cybersecurity of modern automation and control systems used across industry and critical infrastructure. Founded in 1945, ISA develops widely used global standards; certifies industry professionals; provides education and training; publishes books and technical articles; hosts conferences and exhibits; and provides networking and career development programs for its 40,000 members and 400,000 customers around the world. About Rockwell Automation Rockwell Automation Inc. (NYSE: ROK), the world’s largest company dedicated to industrial automation and information, makes its customers more productive and the world more sustainable.

When it comes to industrial fire protection systems, reliability is essential. The system which is often on constant standby during long periods should be able to respond immediately and extinguish possible ignition sources to prevent fires and dust explosions. In the Firefly solution, Stafsjö’s valves have an important duty. For more than 30 years, Firefly have been using Stafsjö’s valves in their fire protection systems. Stafsjö’s valves are robust, reliable, and deliver performance when required. It is a reliable product that provides the quality that our customers’ require. With a closed knife gate valve, fires and dust explosions can be prevented this therefore enhances levels of fire safety for our customers. Stafsjö’s HG isolation valve has a throughgoing gate for reliable shut-off performance which is independent of pressure direction. Its ability to cut through static media columns also serve its purpose well. Superior flow characteristics enable it to act as a part of the pipe system without affecting the process flow. Stainless steel metal seats extend the service life and offers low friction to achieve ultra-fast isolation time. Sometimes the valve is also supported by a pressure tank to speed up the shut-off time. To learn more go to stafsjo-knife-gate-valves-for-fire-protection/ 9
