Claim 0:
1. A rock crusher, comprising:
a crusher unit;
a band conveyor unit arranged to convey crushed rock directly or indirectly from the crusher unit, the band conveyor unit including an endlessly circulating band conveyor;
a magnetic separator held above the band conveyor in a direction opposite from a direction of gravity, the magnetic separator including a magnet and first and second spaced suspension connectors; and
an adjustment unit including:
at least two flexible ties suspending the magnetic separator above the band conveyor, the at least two flexible ties including first and second flexible ties; and
at least one actuator configured to adjust the flexible ties to change a height of the magnetic separator above the band conveyor;

wherein the at least two flexible ties are coupled together for synchronized motion when the at least two flexible ties are adjusted by the at least one actuator; and
wherein the adjustment unit includes at least two rotatably mounted deflectors about which the at least two flexible ties are routed to synchronize the motion of the two flexible ties when the at least two flexible ties are adjusted by the at least one actuator, the at least two rotatably mounted deflectors including first and second rotatably mounted deflectors coupled to each other for synchronized rotation;
wherein the first flexible tie includes a first tension strand connected to the first suspension connector using a first coupling element, the first flexible tie being routed around the first deflector, and the first tension strand merging into a first retaining segment of the first flexible tie beyond the first deflector;
wherein the second flexible tie includes a second tension strand connected to the second suspension connector using a second coupling element, the second flexible tie being routed around the second deflector, and the second tension strand merging into a second retaining segment of the second flexible tie beyond the second deflector; and
wherein at least one of the first and second retaining segments is connected to the at least one actuator.
