Types of Corrugated Steel Silo

According to the bottom type, 2 types of corrugated metal silos are optional:

  • Flat Bottom Silo
  • Hopper Bottom Silo

If your grain reserves are less than 1500 tons, it’s better to purchase a hopper silo, it is convenient for unloading & doesn’t need grain bin cleaning equipment, lower in price;

Hopper-steel-silo

If your grain reserves are larger than 1,500 tons or even tens of thousands of tons, then you’d better buy a flat bottom steel silo.

Because the large-capacity flat bottom silo has a floor foundation, it doesn’t need a bottom support structure like a hopper silo.

hopper-sheets-4

For large-capacity hopper silos, the support structure cost is quite high, therefore, many customers choose flat bottoms for large-capacity silos.

Flat Bottom Silo Advantages

The flat bottom steel silo has the following advantages:

  • Strong Structure for Long Service Life

To improve silo roof carrying capacity, rafters & purlins are optional for your choice.

Grain Silo

What is the Purpose of a Grain Silo?

A grain silo is a bulk material storage facility in agriculture.

It can store all kinds of grains & granular bulk materials, such as corn, soybeans, rapeseed, rice, etc., for long or short periods.

Grain & oil processing plants, feed processing plants, large farms, grain transfer terminals, storage centers, and biofuel companies must equip with grain silos.

corrugated-steel-silo-on-a-large-farm

Agricultural cooperatives or farmers also purchase bins and silos to store grains, seeds, or fermented feed. They store the grain in the silo bin for a certain period, after the grain price meets their expectations, then sell the grain.

Farm grain silo not only solves the storage problem for agricultural cooperatives & farmers but also improves the grain storage quality.

The farm grain silo prevents the powder from directly polluting the air, prevents moisture from entering, avoids material agglomeration, and protects the material better.

How Does a Grain Silo Work?

Speaking of how a grain bin works, it refers to how it loads material, unloads material, and prevents grain mildew.

Whether it is a flat bottom silo or a hopper bottom silo, there is a feed inlet on the roof.

The bucket elevator & drag conveyor loads material into the grain bin from the inlet, and the level sensor monitors the material level when loading.

bucket-elevator-of-grain-bin

Bucket Elevator

When unloading, there is a center outlet & several intermediate outlets at the bottom.

After discharging most of the material from the center outlet, the sweep auger empties the remaining material from the intermediate outlets.

To prevent food mildew, the flat bottom silo & hopper bottom silo equips with temperature control & aeration systems.

With these systems, the temperature & humidity in the silo bin is always normal.

Types of Grain Silos

There are many ways to classify grain bins.

  • Construction Materials

According to construction materials, 4 types of grain storage silos are available:

  • Concrete Silo
  • Brick Silo
  • Wooden Silo
  • Steel Silo

The steel silo is assembled by galvanized sheet, which is light in weight, low in cost, high in standardization, short in the construction period, wide in use, and easy to realize mechanization in factories.

hopper-bottom-silo-sidewall-sheet-1

3 types of steel silo are optional: corrugated, welded, and spiral (Lipp).

  • Purpose

According to purpose, the grain storage silos are divided into the following 3 kinds:

  • Short-term Storage
  • Long-term Storage
  • Transit Storage

Ports, docks, and warehouses along the railway have large grain throughput, there is a lot of grain turnover, and fast loading & unloading is especially important.

Large & medium concrete or steel silos are common, their capacity is more than 50,000 tons, always pair with large loading & unloading equipment to work, and maintain high efficiency in operation.

The unloading equipment lifts the grain from the ship/train to the conveying equipment, after the measuring & cleaning, it enters the grain storage silo.

  • Capacity

3 types are available: large, medium, and small.

Generally, a small grain storage silo’s capacity is 200 tons or less;

A medium-sized grain storage silo’s capacity is 201-1000 tons;

And large silo bins can store grains of 1,000 tons and above.

  • Bottom Shape

There are 2 types: hopper bottom & flat bottom.

How Long Does Grain Last in a Silo?

In theory, as long as the grain’s moisture content keeps at 13% or lower in the farm silo, the grain is always safe in it.

However, most grains are stored from harvest to sale, because the next harvest season needs an empty farm silo.

The silo bin really can store grain for a long time, as time goes by, the grain in the farm silo will gradually lose its nutrition, ultimately affecting the grain price.

Furthermore, the manpower & material resources for storing grain will continue to accumulate over time.

Auxiliary Equipment

Level Sensors

The material level sensor measures the grain level in agricultural silos, the coal level in thermal power plants, and the cement level in cement plants.

Nowadays, the common material level sensors include rotary paddle, weight, heavy hammer, capacitive, microwave, ultrasonic types, etc., in our SiroSilo agricultural silo, it is the rotary paddle type.

rotary-paddle-level-sensor

Rotary Paddle Level Sensor

Each agriculture silo equips with high & low-level sensors.

When loading material, the high-level gauge detects whether the silo is full;

When unloading material, the low-level gauge monitors whether the silo is close to being empty.

Drying Systems

The grain drying silos are agricultural silos with a drying system, this drying system usually includes hot air fans, a stirring machine/system, and so on.

grain-drying-silos

You could click the above photo to watch the presentation video of grain-drying silos.

Aeration Systems

To avoid grain deterioration, the aeration system is essential for the steel silo.

The aeration system has the following functions:

  • Insect Development Inhibition
  • Mold Growth Prevention
  • Seed Vigor Preservation
  • Grain Moisture Reduction

Taking a flat bottom silo with a diameter of less than 8m as an example, a ventilation system includes the following components:

  • Roof Vent

Moisturized air rising from the bottom of the bin escapes through this hole, which is usually round, resistant to standing water, snow, and debris, and has a mesh inside to keep birds out.

corrugated-metal-silo-roof-vent-1

  • Gutter

It is made of hot-dip galvanized steel and installed on the concrete foundation of the silo, “Y”, “H” and “C” layouts are available for you to choose from.

prefabricated-gutter-0

According to the silo size, grain volume, etc., the thickness of the galvanized steel sheet is customizable as per your request.

prefabricated-gutter-1

  • Perforated Floor (Aeration Channel)

The aeration channel is made of perforated metal sheets with a galvanized surface, corrugated, and small holes 1 or 1.5 mm in diameter.

corrugated-metal-silo-perforated-floor-1

The channel distribution is “Y” or “H”, depending on the type and volume of the stored grain.

There is a gutter support under the perforated floor to make the airflow better.

  • Air Fan

Fan intake and cool air, greatly reduce air temperature and humidity and then blows the air into the silo through the aeration channel and the gutter.

Cooled air carries the heat and moisture in the grain to the roof vent.

corrugated-metal-silo-air-fan-1

Larger steel silos introduce multiple fans and aeration ducts for ventilation.

Grain Bin Unloader

The auger grain bin is a flat bottom bin, the flat bottom bin is equipped with a sweep auger for emptying material.

flat-bottom-silo-sweep-auger-0

The hopper bottom bins don’t need a sweep auger, because grain automatically flows out of the hopper bottom bin under gravity.

A sweep auger is a spiral cleaner, it rotates around the center of the silo and clears the remaining grain from the intermediate outlets.

flat-bottom-silo-sweep-auger-4

Grain Bin Construction

The galvanized grain bin construction mainly includes the following basic steps.

Concrete Pad Pouring and Curing

Corrugated grain silos must be installed on a concrete pad to support the weight of a full silo.

So, when you start building a corrugated grain bin, you need to carefully scrape and level the building site, then pour and cure a concrete pad.

concrete-pad-pouring-and-curing-1

Assembling the Roof and the Corrugated Sheets of the 1st Wind Ring

The corrugated steel silo assembly starts from the silo roof and the corrugated sheets of the 1st wind ring.

Bolts, nuts with neoprene washers, and other associated hardware required for assembly are included in the shipment from the manufacturer.

During the construction process, the silo roof is the most vulnerable part, you need to assemble it with great care. You’d better think carefully about the assembly process before doing it.

corrugated-steel-silo-roof-1

Assembling the Corrugated Sheets of the 2nd, 3rd, 4th, 5th… Wind Ring

After assembling the roof and the corrugated sheets of the 1st wind ring, lift the roof and the 1st wind ring with jacks, and then assemble the 2nd, 3rd, 4th, 5th… and other lower wind rings.

Every time after assembling a wind ring, you must lift it to facilitate the assembly of the lower wind rings.

lower-corrugated-sheets-of-steel-silo-1

Anchoring Silo

Drill anchor holes on the concrete pad with a cement drill first, and then use the anchor bolts provided by the supplier to fix the galvanized silo on the concrete pad.

Sealing Silo

To protect the corrugated silo from moisture, you will need to use a foam sealant or tar pad to seal it.

Essential Tools

Two wrenches with long handles are used outside the bin, workers use them to tighten bolts.

wrenches-with-long-handles-1

And impact wrenches are used inside the bin.

impact-wrenches-1

10″ or longer drift punches are especially useful for jacking and aligning corrugated sheets.

drift-punch-1

In addition, lifting equipment is also a must. Common lifting equipment includes jacks specially designed for corrugated metal silo assembly, cranes, boom trucks, large forklifts (small grain silos only!), etc.

Lifting a metal grain silo with jacks will slow down the entire construction process, but using jacks is safer than other equipment.

galvanized-grain-bin-jacking-system-1

Precautions

The total weight of each wind ring plus the corrugated sheets is very large, and a slight bump into someone will cause serious consequences.

Prohibit random personnel from entering the construction site, especially those who are inattentive and careless, which may lead to loss of life or limbs if they are not careful.

Biggest Grain Bin in the World

The United States has the biggest grain bin (corrugated steel) in the world. How much food can it store?

GSI-steel-silo

What is Metal Silo?

Metal silos are cylindrical containers assembled from galvanized sheets, they are suitable for long-term storage of corn, beans, and other grains.

This type of silo is very common near grain & oil plants, feed mills, and ports.

At the top of the metal silos, there is a feeding chute. When loading, the material enters the silo from this feeding chute;

metal-silo-feeding-chute-1

At the bottom of the metal silos, there is a central outlet and several intermediate outlets for taking out the materials.

Hopper Bottom Silo

What is a Hopper Bin?

A silo usually consists of a roof, a body, and a bottom, the roof, body, and bottom of a hopper bin are conical, cylindrical, and inverted conical respectively.

The hopper bin stands on the steel structure legs and brackets, after opening the discharge outlet, the internal grain will automatically flow out from the inverted cone bottom under gravity, with no need for unloading equipment.

Because there is a certain height from the hopper bin bottom to the ground, you could place the belt, screw, or drag conveyor under the bin bottom, and the grain can be discharged at any time as needed, which is very convenient.

Hopper bottom bins are suitable for storing granular items with good fluidity, such as corn, rice, wheat, soybeans, feed pellets, and plastic pellets.

Common cone angles are 45°, 60°, and 66°, the cone angle of corn, wheat, soybean, and feed pellets is 45°, the inclination angle of powder materials is 60°, and for some objects with poor fluidity, the inclination can reach 66°.

Components

Cone bottom silos are usually erected on a metallic structure fastened to the concrete ground.

Its height depends on the number of wind rings, each wind ring height is 1120 mm here in China.

The cone bottom bin comprises the following parts: roof, cylinder, hopper bottom, control system, and auxiliary equipment.

What is the Difference Between Silo and Hopper?

From the perspective of industry cognition, the hopper is more like a classification under the silo, to distinguish it from the flat bottom silo.

The hopper bottom silo & flat bottom silo have different bottom shapes.

Hopper bottom silo is more convenient for unloading, suitable for use as a transit silo, the silo capacity is generally less than 1500 tons, it is cost-effective;

hopper-silo-22

The flat bottom silo is generally used for large-capacity long-term storage, the unloading is not as convenient as the hopper bottom silo.

Volume Calculator

A cone-bottom bin has two cones on top and bottom plus a cylinder in the middle, so you could also use the volume formula for cylinders and cones to determine its storage space.
