Abstract

The transport of iron ore in gondola-type wagons can be affected by the accumulation of rainwater because they are open at the top. To mitigate this issue, drains are incorporated along the entire length of the wagon to enable water drainage. Due to the vibration caused by this transportation method, the compaction of fine ore particles prevents water percolation, leading to drain clogging and hindering effective drainage. Increasing the slot opening of the drains to facilitate drainage could results in the loss of ore onto the railway tracks, generating several transportation problems. This study aimed to quantify the mass loss of pellet feed iron ore on a scale-down experimental bench testing, analysing the ore's particle size distribution and drains with slot opening of 0.6 mm and 1mm. The drain with a 1mm opening caused a 58% loss of the initial mass due to the formation of a preferential water flow from the top to the surface in contact with the drain, with particle transport through turbulent flow. The drain with a 0.6 mm opening did not exhibit a preferential water flow, and the mass loss was on average 12 times smaller than the 1 mm opening.
