1. A piler conveyor system having a distal end, comprising:
an upper conveyor, wherein the upper conveyor conveys a material toward the distal end, wherein the upper conveyor includes a plurality of screening openings through which a debris from the material falls;
a first lower conveyor connected to the upper conveyor, wherein the first lower conveyor is positioned below the upper conveyor, wherein the first lower conveyor receives the debris and conveys the debris toward the distal end; and
a second lower conveyor that is co-linear with the first lower conveyor and that is spaced apart from the first lower conveyer to define an opening between the second lower conveyor and the first lower conveyor;
wherein the debris on the first lower conveyor exits the first lower conveyor at the opening;
wherein the second lower conveyor receives the material from the upper conveyor and conveys the material towards the distal end.
