The National Vari Slot® load out conveyor is a unique design of overhead drag type conveyor used for uniform distribution of bulk materials into trucks, rail cars, containers or bunkers.
The discharge station of the conveyor is comprised of one or more sections, each fitted with an articulating bottom plate which may be controllably positioned to provide the desired material discharge pattern.
Individual articulating bottom plates may be positioned for zero discharge, maximum discharge or selected intermediate rate of discharge.
The choice of which conveyor bottom plates are left in a closed position and which plates are positioned to permit material discharge depends on the desired distribution pattern and the length of the trailer or container to be loaded. Generally speaking, the Vari Slot® conveyor is used for loading trailers, rail cars or containers ranging in length between 20 ft. and 60 ft. (6m to 18m).
