Abstract:The Meisteel raw material system phase 2 project was completed in 2011, and two new QLK800·34 type blending reclaimers with respective design capacity of 1 400 ton/hour were built. In view of the equipment running so far, though the main structure is good, such problems exist as big vibration of the reclaimer, severe wear of supporting roller of the bucket wheel, serious deformation of bucket wheel, breaking of circular track and frequent fall-off of driving chain of bucket wheel system etc. In this paper, the causes of the above-mentioned problems were analyzed, and corresponding technological transformation schemes were put forward. After the transformation, the operation stability of the blending reclaimer has been improved and the stable operation of the production has been ensured.
