A Review of Bucket Wheel Reclaimer Failure Through Mechanical Test and Metallographic Analysis
The present article provides description of a catastrophic failure of a Stacker-cum-Reclaimer in one iron ore mining area in India. The failure invited a detailed review into the possible causes of failure through onsite inspection, mechanical testing and metallographic analysis. A review of the collapse structures at site revealed a few critical operational reasons clubbed together with metallographic conditions as the triggering causes of failure. Based on the findings of visual review, mechanical tests and metallographic analysis a few recommendations are made to avoid such failure in future.
