Dual conveyor system

In a bulk material conveyor system having an input end and an output end, a conveyor apparatus which is secure against mixing of dissimilar conveyed materials which are being conveyed simultaneously and which comprises:

• a housing structure formed of a pair of opposed section means;
• a means for separating said pair of opposed section means to form upper and lower passageways;
• a single continuous chain conveyor means disposed centrally within said upper and lower passageways, an upper portion of the said conveyor means being positioned within said upper passageway and being supported by and riding on the upper surface of said means for separating said pair of opposed section means, and a lower portion of said conveyor means being positioned within said lower passageway;
• means for driving said continuous conveyor means;
• a plurality of dual flight means spaced along and carried by said continuous conveyor means;
• bulk materials receiving means disposed at the input of said conveyor system for receiving bulk material, said bulk materials receiving means having separate ports to receive two said dissimilar materials;
• separate conveyor chamber trough means in said lower passageway to maintain separation of said dissimilar materials, and in which separate sections of said dual flight means travel;
• and
• discharge means at the output end of said conveyor system, having separate ports to said separate conveyor chamber trough means to discharge two said dissimilar materials.
