Silo tanks have been in use since centuries for the careful storage of feeder and grains mainly but not restricted to food grains, wood material and organic fodder. Nowadays the relevance of Silos and Storage tanks in the agriculture industry is notable to observe for its growth and almost mandatory installations across Indian industries. They ensure the material inside the storage Silos are obtainable - by that it retains all essential nutrients that can be available for direct consumption or further production. In a country with striking climatic conditions, Silos make for the safest option to store precious commodities like food grains which feed the nations populous.
Silos are the most common sights for engineered steel/concrete structures that hold velocities of materials in them. Silos can be used in the:
Agricultural Field: Grain sorting, refining and storing
Chemical Field: Storage of highly combustible chemicals and plastics
Construction Field: Storage of cement, natural oxides, and occasionally specific building materials like carbons, plaster mixtures and raw materials.
Silos have a geometrical aspect which is similar to that of a cylinder with sizes ranging from 50,000 to 100,000 tones capacity holders of various types of materials. The easy moveable variants like the horizontal silos make it convenient for distribution and transportation.
2. Internal Storage
The internal storage is built for storing - loading and unloading of goods becomes a simple task when off-loading trucks carry the silo materials from the opening ducts which work by either gravity, as most of these Silos are tall in shape. Inbuilt pumps, temperature regulators and automated designs are also seen in some sophisticated silos meant for storing high voltage/inflammable liquids.
3. Materials Used
The materials that are used to build silo storage tanks are high quality wood, double coated plastic, layered concrete and even stainless steel.
The famous stainless-steel Silos are the most popular ones, seen in the fields and grasslands of various terrains across Indian plains and developed countries like Germany, USA, France and South Africa.
4. Weight and Cost
The weight of Silos is important to note for industrial purposes. Normally Silos which are made of steel are nearly half the weightage of concrete and rigid Silos which are reinforced to create greater depth and volume. The next feature of Silos is that they are cost efficient. It takes 20%-50% less capital investment to acquire a silo with normal functionality. The advanced Silos come with technical upgradations and such customizations can be expensive to build. The overall structure is engineered in such a way so as to provide the best storage product to the industry.
5. Fast Installation Period
It takes a mere 15 days to construct a well-built 6,000 tones holding capacity Silo. While wet work is required for the production of concrete silos it may take more than 30 days to be built. The process is fastened by on site building of the reinforced layered concrete silo. The installation and manufacturing of Silos is rather quick as compared to other complex storage systems. The availability of prefabricated steel and other easily made parts speeds up the period to completion by 10x faster rate.
6. Placement Efficient
Silos are limited to a particular size and shape. Irrespective of the tallness or wideness, they are already specified to the manufacturer and come in standard sizes which are placement friendly especially in spaces where there is shortage of area.
7. Service Life: Highly Durable
Some Silos can last a good 40-50 years as they are exempt from storage of volatile substances and goods and very low maintenance cost. And the stainless-steel variants even last for 20 years self-life as they have higher maintenance cost per year added to their existence.
It is noted to always spend a little more on antirust and corrosion plasters to ensure good durability of Silo storage tanks.
8. Maintenance Cost
The maintenance cost depends on the material. The Silo predominantly consisting of steel has higher cost in maintaining and cleaning rusty edges and surfaces due to rain, and additional paint jobs are mandated every couple of years. Here the concrete Silos take stride as they do not require maintenance of high-cost extraction like painting as such even after completion.
9. Leakage Performance
Silos are air tight and moisture proof. They need to be as their storage goods demand such features for proper keeping. Gridlock concrete silos have rain proof material to combat against climatic challenges. The walls of some Silos are insulted with a double rubber layer to regulate and de-pressurize the air within to match the changes in the air temperature outside.
10. Design Importance
The design of Silo structures has details which suit that particular material to be stored, that location to be placed and that environment to be in. All Silos adhere to the characteristic features of being high-quality, high strength and strong earthquake resistance. Natural calamities are an unforeseen but inevitable occurrence and the design layout of Silos are built to withstand the harsh weather.
