How Does a Portable Concrete Plant Work?

A portable concrete batching plant is equipment used to produce concrete on the site of a variety of construction projects. Because it’s portable, it can be moved to a number of locations around the job site, and transported to virtually any project.

We’ve put together a guide for those curious about how a portable concrete batching plant works. To start, let's walk through the various components and stages involved in concrete batching.


Introduction: Portable Concrete Batching Plant

Portable Concrete Batching Plant Parts

While a portable concrete batching plant and a stationary one may look very different, both types of plant each utilize the same components.

  • Bins and Silos:

    Used to store all the necessary ingredients to mix concrete.

  • Conveyors:

    Used to transport aggregate to the mixer.

  • Augers:

    Used to transport cement to the mixer.

  • Weight and Metering Devices:

    Used to measure the water and additives before being combined with the raw materials.

  • Mixing Unit

    This is where all the various ingredients are combined to form concrete.

  • Control Panel:

    Used by the operator to control the mixing process.

All the materials are combined in the mixer. The mixing time and speed will depend on the type of concrete mixture being produced and can be adjusted using the control panel.

Concrete Mixing Stages

No matter what type of batch plant you’re using, the process for producing concrete is relatively the same and comprised of six stages.

Stage 1: Material Preparation

Concrete is made up of three primary ingredients: cement, aggregate, and water. Other additives may also be included depending on the mixture being used.

This initial stage involves simply gathering these materials and storing them in bins and silos so they are ready to be combined.

Stage 2: Transportation

Before mixing can begin, the operator must determine how much concrete they actually wish to produce. Once this is decided, the mixer is started and materials can begin to be transported.

Aggregate and cement are released from the bins and silos, moved via conveyor belts and augers, eventually being deposited into hoppers for weighing.

Stage 3: Weighing

In order to produce a quality mixture of concrete, the ratio of each ingredient must be correct. Hoppers weigh both aggregate and cement to ensure the correct amounts are used. Water and any necessary additives are also weighed or metered.

Stage 5: Mixing

All the materials are combined in the mixer. The mixing time and speed will depend on the type of concrete mixture being produced and can be adjusted using the control panel.

Stage 6: Finished Product

After the mixing is complete, the finished product is discharged from the mixer and is ready to be poured in the desired area.

"Portable concrete batching plants are often a more cost-effective solution than a stationary plant. They produce better quality concrete, since the concrete and can be poured right after it’s mixed."

Differences Between Portable Concrete Batching Plants and Stationary Plants

While, for the most part, the components and process involved in mixing concrete are relatively the same between both portable and stationary plants, there are some important differences between the two.

For starters, mobile concrete batch plants are much smaller than stationary plants. Not only are their components smaller, but the various parts are placed much closer together to save space.

Mobile plants can also be easily transported from one area to another while stationary plants must remain in one location. This allows mobile plants to be placed directly on jobs sites, while any concrete produced by a stationary plant must be transported in a drum truck to where it needs to go.

Because of these key differences, portable concrete batching plants are often a more cost-effective solution than a stationary plant. They produce better quality concrete, since the concrete and can be poured right after it’s mixed.

Finally, because portable plants don’t require concrete to be transported to job sites they save on cost and produce less harmful emissions, making them better for the environment.
