Fertilizer in a blend plant is stored in side-by-side bins. That way it is easily accessible to be mixed and hauled onto the field. Note that most of the bins are made of wood walls. The floors are made of concrete. As soon as the first fertilizer is put in the storage, the floors start collecting the condensation that mixes with the fertilizer.

Why a Monolithic Dome Fertilizer Blend Plant?

Cutting-edge, money-saving technology that safely maintains the quality of your product

What’s a fertilizer blend plant’s number-one enemy?

Moisture! If water gets into or condensation forms inside a storage unit, it quite quickly begins degrading the fertilizer and forming rust.

But Monolithic uses a technology that keeps that troublesome process to a minimum.

We construct our domes of steel-reinforced concrete, insulate them with polyurethane foam and air condition them. That creates important advantages:

Moisture Control

Most structures designed for storing and blending fertilizer are not insulated or air conditioned. Monolithic plants are! The domes are waterproof. Their one-piece concrete construction literally locks out moisture. Their insulation and cooling system prevents inside condensation and provides a far more comfortable and healthier environment for workers.

We use affordable, one-ton air conditioners – window units like those used in homes.

Low Energy Costs

Monolithic Domes are super energy efficient. It takes far less energy – 50% to 75% less – to cool a Monolithic Dome than it does to cool other, similar-size structures.

The dome’s interior temperature stays consistent and fluctuates very little, regardless of the outdoor temperature. That kind of energy efficiency translates into long term, low energy costs.

Disaster Resistance

Monolithic Domes meet FEMA’s structural criteria for providing near-absolute protection. They can survive, and have survived, tornadoes, hurricanes and earthquakes. They are fire-resistant and bullet-resistant. They cannot be easily penetrated by terrorists. And they will not rot or get eaten by termites.

Circular Shape

The domes can be built in any size. More importantly, their circular shape allows for minimal travel of load-out equipment.

Low maintenance; High Durability

Monolithic Domes require a minimum of upkeep, but they have a lifespan of 100+ years.

We have been successfully designing Monolithic fertilizer blend plants since the late 1970s. We’d like to help you design yours. Please contact us: [email protected] or 972-483-7423. And please review www.monolithic.com for more information.

This floor is seriously deteriorated from the effects of the chemicals coming out of the fertilizer as it mixes with the moisture in the air.  Monolithic Dome blend plants do not have this issue because our domes are super insulated, and simple, window A/C units can keep all of the excess moister out of the dome.  Monolithic also includes a special additive in its concrete to reduce the effects of chemical attacks.

This is a picture of a Monolithic Dome blend plant.  Notice the difference in the condition of the floor and bin walls.  Concrete bin walls can take the abuse that loader operators will throw at it.  Loaders, conveyers, scales — everything is kept dry and rust free!

Here is an example of wooden bin walls.  Notice the abuse that these walls have taken over the years of loader operators hitting them. Try that on a concrete wall and you may have to fix the loader.  All of the product that is within the walls and on the wet floor is lost product.  The next image shows the inside of a Monolithic bin.

Our design of a rotating incoming conveyer is unique. The incoming conveyor brings material from the elevator outside and drops it into the center. Then it can be rotated to drop the product into the bin of choice. The dome can support any loads you can hang off it.  All of the material handling equipment is supported off the dome.  Catwalks provide access to each moving part, so maintenance is simple.
