Abstract

The gondola cars employed in the transportation of iron ore feature an opening at their top, allowing the accumulation of free water during railway transit. To address this issue, drains are incorporated throughout the entire length of the car to facilitate water drainage. Due to the vibration induced by this mode of transport, the compaction of fine ore particles tends to decrease or prevent water percolation to the drains. The objective of this study was to compare the compaction characteristics of two ore types, sinter and pellet feed, using an experimental bench proposed by the authors and a standardized electromagnetic sieve shaker employed in particle size characterization. The electromagnetic shaker induced more substantial compaction in both ores compared to the experimental bench, representing an extreme case of vibration intensity. The compaction profile exhibited similarities in both mechanisms, with the initial minutes showing a more pronounced decline in the ore pile level, followed by a plateau until the conclusion of the experiment.
