What Is Silo? Types Of Silo

NPEC SILOS- Engineered to Perfection In its Greek form, a silo means a “pit for holding grain”. It is a tall structure or pit on a farm used for stocking up bulk materials and is used in agriculture for the purpose of storing grain or fermented feed, known as silage. Silos are more frequently used for storing bulks of grain, carbon blackcoalcementwood chipssawdust, and food products.

Archaeological ruins and historical texts are evident that silos were used in ancient Greece dating back to the late 8th century BC.

The silo pit has been a convenient and favorable way of storing grain from ancestral Asia. Fred Hatch invented and designed the first and modern silo, a wooden and vertical one crammed with grain, in 1873.

Types Of Silo

There are three major types of silos used widely in time: tower silos, bunker silos, and bag silos.

Tower silo

Tower silosare one of the most common silos used. It is typical of a cylindrical structure, usually 10 to 90 ft in diameter and 30 to 275 ft in height. The Slip and Jump form of concrete silos are the taller silos with larger diameters. The tower silos may comprise materials like wood staves, cast concrete, concrete staves, and steel panels. Its costs, durability, and air-tightness trade-offs may vary. Silos storing grain, cement and woodchips are generally discharged with air slides or augers. Silos can be unloaded into rail cars, trucks or conveyors.

Bunker Silos

Bunker Silos are troughs, usually owning concrete walls with a packed trench that is enclosed with a plastic tarp to sustain its air-tightness. Tractors and loaders usually unload these silos. They are easy and inexpensive, standing ideal for large operations.

Bag silos

Bag Silos are another type of Silo used frequently in the world today. These are heavy plastic tubes, generally around 8 to 12 ft in diameter, and of variable length as deemed necessary by the amount of material to be piled. Bag Silos involve minimum capital investment and can be used as a short-term measure when growth or harvest conditions demand more space.

Some other silos generally used are:

Cement storage silos

Cement silos are structured in different kinds, such as the low-level mobile silo and the static upright cement silo. Cement silos are basically employed to hold, and discharge cement and other powdery materials like PFA (Pulverized Fuel Ash).

The low-level silos are fully mobile with capacities ranging between 100 and 750 tons. They are easy to transport and convenient to operate on the work site. A weighing system with a digital display and printer are outfitted to the mobile silos which permit the innumerable quantity of cement or powder discharged from the silo to be controlled. The static upright silos possess capacities varying between 200 and 800 tons. These silos are considered as a low-maintenance option for the storage of cement or other powdery materials.

Concrete Stave Silos

Concrete Stave Silos are built from common components designed ideally for high strength and long life. Constructed from small precast concrete blocks with grooved channels along each edge into a high strength shell, Concrete Stave Silos are much stronger in compression than tension. They have the striking feature to stand flexible to have their height increased as deem necessary to the needs of the farm and purchasing power of the farmer, or if no longer needed, to be completely dismantled and replace it.

Low-oxygen Silos

Low-oxygen Silos are predominantly designed to store its contents in a low-oxygen atmosphere to help retain the fermented contents in a high-quality state, and to prevent them from mold and decay. Low-oxygen Silos are opened directly to the atmosphere only during the initial forage loading.


Bins are characteristically is much shorter than a silo and is generally used for holding dry matters such as cement or grain or powdered substances such as seed kernels, or as cob corn. Bins may vary in its shape, could be round or square.

Fabric Silos

Fabric Silos are made of a fabric bag perched within a rigid, structural frame. Polyester based fabrics are often used for the purpose of fabrication of the bag material. Fabric silos are a suitable option for work sites because of their low-cost investment compared to conventional silos.

Sand and Salt Silos

Sand and salt silos are used for winter road maintenance and are stored in conical dome-shaped silos. These are highly common in North America, namely in Canada and the United States.
