Joest highlights importance of advanced measurement technology

first_imgIn an extremely tough economic climate, condition monitoring is gaining momentum in the mining industry as a cost saving option that enables plant operators to monitor equipment output, pre-empt failures and capture valuable long term data on plant performance. While conventional condition monitoring tracks a specific parameter of condition to identify a change indicative of a developing fault, vibrating and screening equipment specialist Joest says it has added advanced testing and measuring technology to the mix, helping customers achieve a continuous supply of quality production tonnage, while protecting company assets and reducing the total cost of ownership.“Our activities in this area are focused on mitigating the risks associated with each unique customer plant,” Theresa Walton, General Manager Service at Joest, comments. “We differentiate ourselves in the marketplace not only through the quality of our products, but also by the high level of service we offer and by the advanced testing and measurement technology we’ve developed. Joest has never shied away from investing in technology and this capability allows us to enhance our offering to customers, enabling the early identification of conditions that would shorten the equipment’s lifespan — before they develop into a major failure. The longer we can extend the life of our equipment on site, the better value the customer will extract from this investment.”Walton predicts that the role of condition monitoring/testing and measurement in the future is likely to increase in order to counter a growing trend in the mining industry worldwide to specify lighter screens and associated support structures when a plant is first designed, in an effort to contain costs. Joest says it tailors its test and measurement technology to suit each customer’s specific needs, taking into account skills levels at the plant, as well as production and quality requirements, and linking these factors to existing systems. Based on this customised approach, the company is in the process of installing sensors on its equipment at several customer plants.“However, installing dozens of sensors doesn’t take away from the need to maintain the equipment to operate within its specifications and to refurbish it within appropriate cycles,” she comments. “There is also an important role for human observation of equipment and performance. All these factors combine to extend the life of the plant.” Kenny Mayhew-Ridgers, Joest’s General Manager for Engineering, adds that in the absence of a standard commercial solution available on the market to offer high end condition monitoring on vibrating equipment, this South African-owned OEM “conducts in-house research and development to arrive at the right approach for each application, in collaboration with its customers.”“We find that the condition monitoring vibration sensors associated with SCADA systems, which were originally designed for applications in rotating equipment, cannot provide the required measurement range for our vibrating equipment, because we far exceed its maximum levels,” he says. “This is why we include ‘test and measurement technology’ into our approach when advanced condition monitoring is required. Every site has different demands and it’s extremely important to listen to these needs and understand the level of skills and capabilities at a given plant. We believe that by working with the OEM, who has an absolute understanding of the equipment’s characteristics, plant operators can be assured of the ideal monitoring technology.” Before its screens are despatched to customer sites, Joest tests each unit to record the baseline measurements, and once installed, further tests are conducted to establish the influence of the plant structure and full load conditions on the unit and determine the tolerable variances. These measurements are proving invaluable in flagging deviations and achieving long term optimisation of equipment performance.last_img read more

Sustainable development agreement between ICMM and Chinas CCCMC

first_imgThe International Council of Mining and Metals (ICMM) and the China Chamber of Commerce of Metals, Minerals and Chemical Importers and Exporters (CCCMC) announced today that they have entered into a formal agreement to help promote sustainable development in Chinese companies’ overseas mining investments.The new agreement makes ICMM and CCCMC’s wealth of expertise available to Chinese mining enterprises that are looking to further improve their environmental and social performance practices, as they step up their presence worldwide. In recent decades, overseas investments by Chinese companies have increased significantly.Chinese overseas mining investments are a relatively new phenomenon and Chinese mining companies are often newcomers in the economies of resource-rich countries. They are, however, increasingly becoming the most significant investor in many countries and this is likely to continue.Dr Nicky Black, Director of Environment and Social Progress at ICMM said: “We are looking forward to working with CCCMC. This new agreement will enable us to both learn from each other and further improve the environmental and social performance of the mining sector.“Supplying the growing demand for metals and minerals sustainably is a challenge facing us all and I believe that our new agreement with CCCMC will be a very productive partnership.”Mr. Sun Lihui, Director, Development Department CCCMC said: “CCCMC is interested in working with ICMM, to complement each other’s strengths and to learn from each other. This will help continually improve the risk management and governance of mining companies, enhancing business opportunities while reducing risks.”ICMM and CCCMC are important industry organisations in the international arena, our strategic cooperation will advance sustainable development in the mining industry” he added.The MoU will also help Chinese enterprises address the new challenges that the UN’s 2030 Agenda for Sustainable Development place on industry, governments and civil society alike through its ambitious Sustainable Development Goals (SDGs).Globally, the extractives sector is under intense scrutiny. Stakeholders (especially governments, communities, investors, insurers and civil society) have expressed concerns about the sector in terms of its environmental and social performance and the sector’s contribution to poverty reduction and sustainable development.This Memorandum of Understanding will help Chinese overseas mining operations to meet society’s environmental and social performance expectations, and to successfully adhere to increasingly stricter environmental and social performance standards.last_img read more
