The main difference between Silo and Granary is that the Silo is a structure for storing bulk materials and Granary is a storage building for grain
Silo
A silo (from the Greek σιρός – siros, “pit for holding grain”) is a structure for storing bulk materials. Silos are used in agriculture to store grain (see grain elevators) or fermented feed known as silage. Silos are commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Three types of silos are in widespread use today: tower silos, bunker silos, and bag silos.
Granary
A granary is a storehouse or room in a barn for threshed grain or animal feed. Ancient or primitive granaries are most often made out of pottery. Granaries are often built above the ground to keep the stored food away from mice and other animals.
