A cylindrical screen having a plurality of openings is situated lengthwise within the housing to correspond with the first and second zones. A conveyor is situated lengthwise within the screen and includes an elongated shaft having a first and second conveyor section and along a length of the conveyor that corresponds with the first and second zones, respectively. Each conveyor section is configured to move material in a direction along a length of the screen.
