Abstract (en)

[origin: CA3143747A1] A system (10) for screening ballast comprises a first screen (26) and a second screen (28) which is located behind the first screen (26) in a first direction (100). A discharge collection conveyor (32.1) is located directly under a first discharged ballast outlet (42) of the first screen (26) in order to collect a flow of discharged ballast which comes from the first screen (26) and to convey it in a second direction (200) counter to the first direction (100). A rerouting collection conveyor directly collects the flow being discharged from a screened ballast outlet of the second screen in order to convey it in the first direction (100). The rerouting collection conveyor extends under the first screen (26) at a lower height than the discharge collection conveyor.
