Review of failure mode, effect and criticality analysis (FMECA) on major equipment of the crushing and screening plant at the BORAL Quarry at Ormeau, Queensland

摘要

This project was aimed to improve the reliability of the BORAL hard rock crushing and screening plant at Ormeau. A literature review was documented, highlighting the reasons for FMECA and the process involved in carrying the procedure out. A review of BORAL downtime data was conducted, which identified problem machines that were large contributors to downtime. A study of the plant identified the critical path of the plant and functional diagrams showed dependencies between systems of individual machines. The FMECA required ground rules for a true and consistent evaluation. The FMECA was conducted, criticality values were given to failures and recommendations made to prevent, predict, and fix failures more quickly. The recommendation were expanded apon and developed into an item that can be used by staff to implement the recommendations
