The Difference Between Grain Bins and Silos
Is that a bin, or is that a silo? What’s the difference between the two structures?
A silo serves sort of like a coffee thermos: tall, skinny, seals tight and holds moisture. Silos often are blue or the color of concrete. They traditionally store silage, which is grass or other fodder harvested green and wet, primarily to feed dairy cattle.
Bins are vented, silver, corrugated steel structures fatter in diameter than silos and have varying heights. They generally store dry corn and soybeans, which meet domestic or export market demand for feed, food and fuel use.
