Claim 7:
8. A mobile multi-deck screening apparatus, comprising:
a feeder configured to receive material for screening;
a first screen deck configured to receive the material from the feeder;
a first discharge conveyor configured to output an oversize fraction of the first screen deck;
a second screen deck configured to receive an undersize fraction of the first screen deck;
a second discharge conveyor configured to output an oversize fraction of the second screen deck;
the first discharge conveyor being pivotably mounted to operate in a direction selected between a first direction and a second direction, wherein the second direction differs from the first direction;
the second discharge conveyor being pivotably mounted to operate in a direction selected between the first direction and the second direction;
at least one of the first and second discharge conveyors being pivotably mounted to operate further in a direction selected between the first direction and a third direction;
the first direction being between the second and third directions;
the first direction being forward;
the second and third directions pointing to opposite sides of the mobile multi-deck screening apparatus;
wherein the first discharge conveyor and the second discharge conveyor have matching shapes such that the first discharge conveyor and the second discharge conveyor can be pivoted so that the second discharge conveyor is operated aligned with and under the first discharge conveyor
the mobile multi-deck screening apparatus further comprising co-piling equipment selectively causing piling in a same pile oversize fraction material of the first screen deck and oversize fraction material of the second screen deck; wherein
the co-piling equipment comprises the first discharge conveyors and the second discharge conveyor directed to discharge material to the same pile, when the first discharge conveyor and the second discharge conveyor are in a same direction.
