What should a Korber Grain Silo interior look like?

Two considerations. One the moisture content of received grains is extremely important and would be checked before grain is added to a silo. Supplier of the grain is paid for the grain, less the moisture, with an added charge for removing the moisture.   Too high of a moisture content requires drying, most likely a separate facility.  Two, Dust needs to be controlled, can be explosive. The conveyance system, would be contained, most likely augers, not open belts, anything to confine the dust.   IMO.

The area with the elevator (i.e. Leg) could have more than one leg in it. Normally you would see two legs one for wet grain and one for dry grain, the wet the wet leg would go to the facility dryer (drying system) the dry leg would go to the storage tanks or bins this would discharge from the leg into a conveyor system running across the top of these tanks inside the building on top of the tanks this is usually called the head house. Under the tanks you would have what is called a reclaim system to get the grain out of the tanks. This grain normally goes back thru the dry leg to a load out system. The system would use round or square spouts to transfer grain from one piece of equipment to another. All systems in a grain facility should be closed to help prevent dust.

Quite often, there is no basement. The bottom silo cones, chutes, and conveyors are all at ground level. The "storage" portion of the silos actually ends about one or two "floor levels" above the ground, even though the concrete silo structure extends on down to ground level.
