Abstract

The formation of free water in gondola-type open wagons for transporting ore is a problem to be mitigated in rail transport, because even with the use of drains at the head and floor, the accumulation of water always occurs, both due to the compaction of the ore fines that form a very dense pulp as well as by clogging the drains. This project aimed to develop an experimental bench to evaluate the efficiency of drains used in wagons to transport iron ore, evaluating the effects of moisture and ore compaction on percolation and drainage, as well as the effects of vibration on compaction of particulates. Important aspects were observed in the tests with sinter feed ore, such as the initial mass concentration of water. The higher the humidity at the beginning of the test, the longer it took to eliminate the same amount of water added to the ore surface. As for vibration, the percolation time of a water column and subsequent drainage compared to the static test shows a value 10 times greater.
