  • Root cause analysis of bowl-mill pinion shaft failures

    2013-4-1 · After a detailed examination of the operating history, it was observed that at the time of the failure, hard, rock-like lumps were present in the inlet coal discharge and they were struck in the bull ring segment as they could not be crushed. One of the bowl mill roll also was damaged as a result of this blockage . This led to locking of the bull ring segment, which led to sudden overloading of the entire

  • Investigation of critical failures using root cause

    2017-3-1 · Fault tree analysis (FTA) is a systematic “top-down” failure analysis technique that gradually progresses deductively from the emergence of an unwanted event (also known as the “top event”) to the identification of the causal factors (also known as “basic events”) of that particular unwanted event . Besides identifying the root causes of the unwanted event, FTAs can equally show the causal

  • A Guide to Failure Analysis for the Oil and Gas Industry

    2018-12-6 · Failure analysis and prevention is often a complex multidisciplinary activity requiring broad knowledge in areas of design, manufacturing, materials, mechanics, and testing. In the oil and gas industry, failure modes include corrosion, fracture, cracking, fretting, distortion, and thermal damage. Failure analysis activities are conducted as part of the

  • M. Keyßner, T. Fahrland, Loesche GmbH, Duesseldorf

    2017-8-12 · Without question, the capacity and drive power requirements of cement- and slag- grinding mills has been steadily increased. For example, in 2006 mill capacities of about 220 t/h equated to 5500 kW of maximum power demand. Nine years later, in 2015, the maximum mill through- put had increased to around 500 t/h with.

  • Bearing damage and failure analysis

    2020-12-8 · Analysis requires a good understanding of path patterns. 4 ISO failure modes classification Terminology and the ISO classification system helps to communicate the type of damage and its possible causes. 5 Damage and actions A number of cases are described together with corrective actions. In this chapter, only non-des tructive analysis is covered.
