1. A method of piling up debris using a piler system, comprising the steps of:
transferring a material onto an upper conveyor, the upper conveyor comprising a plurality of screening openings, an inner end and a distal end;
conveying the material with the upper conveyor such that a debris from the material falls through the plurality of screening openings onto a lower conveyor positioned underneath the upper conveyor;
conveying the debris upwardly in a first direction towards an outlet end of the lower conveyor by the lower conveyor;
dispensing the debris by the lower conveyor from the outlet end of the lower conveyor into a first debris pile underneath the outlet end of the lower conveyor;
conveying the material upwardly in the first direction towards the distal end of the upper conveyor to be dispensed into a material pile by the upper conveyor; and
rotating the upper conveyor and the lower conveyor together about a vertical axis such that the lower conveyer dispenses debris from the outlet end of the lower conveyer into a second debris pile underneath the outlet end of the lower conveyor at a position different from a position of the first debris pile.
