Sugar would be transported in either Airslide (usually 2 bay) or Pressure/Differential hoppers (3 or 4 bay). Both have round roof hatch openings and the P/D hoppers will have piping along the lower side for attaching the pneumatic hoses. The Airslide hopper has special discharge gates and a pneumatic hose is also attached to them to facilitate unloading. Sugar, flour, etc., would not be handled in covered hoppers with trough hatches and gravity discharge gates as those type hatches and discharge gates would allow contamination of the commodity. The type of roof hatches and discharge gates do make a difference.
Grain would be transported in gravity discharge hoppers usually with trough hatches and are three bay hoppers. Doing an Internet search for Airslide covered hopper, Pressure differential covered hopper, and grain covered hoppers should result in plenty of examples.
Not sure what sort of 2 bay covered hoppers you have. Perhaps you can post an example and I can give you a better idea of what those would be used to transport. Most of the short, 2 bay hoppers you see are for transporting cement or similar heavy commodities.
