Abstract
A system () for sieving ballast comprises a first sieve () and a second sieve () which is located behind the first sieve () in a first direction (). A discharge collection conveyor () is located directly under a first discarded ballast outlet () of the first sieve () in order to collect a flow of discarded ballast which comes from the first sieve () and to convey it in a second direction () counter to the first direction (). A rerouting collection conveyor directly collects the flow being discharged from a clean ballast outlet of the second sieve in order to convey it in the first direction (). The rerouting collection conveyor extends under the first sieve () at a lower height than the discharge collection conveyor.
