Maintenance for mine profitability
Mining operations and manufacturing facilities rely on the continued safe operation of vehicles and machinery to maintain profitability. Any equipment failure can be expensive in terms of lost production and cost of repairs. An estimate for the cost of lost production for a single dragline is $8000 per hour in Australia making any breakdown very costly when it might take weeks for a replacement part to be available. One way to minimise losses is to continually monitor plant and machinery using non-destructive testing (NDT) methods to ascertain component health, and monitor mechanisms for damage. Phased array ultrasound can enhance day to day inspection of surface mining equipment, thereby improving safety and keeping critical equipment operational. However, it is important that inspections are performed with minimal down time, so need to be planned and coordinated to ensure that critical parts are available when the maintenance is carried out. As part of the technical programme at the recent Australian Institute for Non-Destructive Testing (AINDT) Conference in Brisbane, Nicholas Bublitz, a Global Product Support Specialist with Olympus Scientific Solutions America (OSSA), reported on how the use of phased array ultrasonics could improve surface mine profitability. NDT is a group of techniques used to detect discontinuities in materials or components without causing damage or permanently altering the article being inspected. The AINDT Conference provided opportunities for NDT and maintenance professionals to meet and discuss the latest advances in NDT from around the world. Leading corporate members of the Institute, such as Olympus, displayed and demonstrated some of their innovative, precision analysis instrumentation and applications supporting NDT. “NDT methods like ultrasonics, eddy current and radiography—along with condition monitoring techniques such as oil and vibration analysis—play an important part in predictive maintenance programs and help reduce unexpected expenses,” Bublitz said. Outage and emergency repair costs can […]
