We are seeking innovative solutions to unload iron ore fines from wagons within 165 minutes regardless of their stickiness.
Iron Ore Fines are transported from mines to manufacturing site in BOBSN Rakes. These Rakes are unloaded at various Track Hoppers (TH) and then supplied onwards.
BOBSN type of wagons are side-discharge type, where the doors on both the sides of wagons are opened and Iron Ore fines (IOF) is expected to flow down from wagons, under gravity, into the hoppers below, from where it then gets transported through a series of Conveyors. However, at times the IOF does not flow under gravity because of stickiness and requires poking of the floor and walls of the wagon to create vibration and make IOF flow. Stickiness depends on multiple factors such as mineralogy index, moisture, and weather.
Wagons having non-sticky IOF gets unloaded within 120 minutes, whereas the Wagons with Sticky IOF may take up to 20 hrs.
The problems faced because of stickiness are as below.
Owing to the above problems, we are seeking solutions to unload iron ore fines from wagons within 165 minutes regardless of their stickiness.
The proposed solution should address one or both of the following requirements:
