Transfer conveyor assembly for a screening apparatus
First Claim
1. A transfer conveyor assembly for a screening apparatus having a top screen deck, an upper intermediate screen deck, a lower intermediate screen deck and a bottom screen deck, the transfer conveyor assembly comprising:
- a first transfer conveyor that is oriented transversely with respect to a feed direction of the screening apparatus and is configured to receive material from the top screen deck such that the material is stockpiled or fed to a further conveyor;
a second transfer conveyor that is oriented transversely with respect to the feed direction of the screening apparatus and is configured to receive material from the upper intermediate screen deck such that the material is stockpiled or fed to a further conveyor;
an upper intermediate transfer conveyor that is configured to convey material from the lower intermediate screen deck out from underneath the first and second transfer conveyors to a position away from the first and second transfer conveyors in a discharge direction of the screening apparatus;
a third transfer conveyor oriented transversely with respect to the feed direction of the screening apparatus, the upper intermediate conveyor being configured to discharge material onto the third transfer conveyor such that the material is stockpiled or fed to a further conveyor;
a lower intermediate transfer conveyor that is configured to convey material from the bottom screen deck out from underneath the first and second transfer conveyors to a position away from the first and second transfer conveyors in a discharge direction of the screening apparatus; and
a fourth transfer conveyor oriented transversely with respect to the feed direction of the screening apparatus, the lower intermediate conveyor being configured to discharge material onto the fourth transfer conveyor such that the material is stockpiled or fed to a further conveyor.

Abstract
A transfer conveyor assembly for a screening apparatus includes at least one transfer conveyor that is oriented transversely with respect to a feed direction of the screening apparatus and is configured to receive material from at least one respective screen deck of the screening apparatus. At least one intermediate transfer conveyor is positioned with respect to at least one further screen deck of the screening apparatus to receive material from the at least one further screen deck to feed material to a position away from the at least one transfer conveyor in a discharge direction of the screening apparatus.
