What is a Concrete Plant?
A concrete plant makes concrete through machinery, precisely batching and mixing cement, aggregates (sand and gravel), water and admixtures. Raw materials like cement, sand, gravel and additives are stored in separate compartments or bins. The weighing system carefully measures the required quantities of each material based on the specific concrete mix design.
Measured materials are then fed into the batching plant where they are combined. Finally, the mixing unit blends all the ingredients thoroughly with water to produce fresh concrete with the desired workability and strength properties. Ready-mix concrete is loaded into truck mixers and transported to construction sites for various applications like foundations, structures, pavements, etc.
An automated and well-calibrated concrete plant allows JEL Manufacturing to supply customers with consistent, high-quality concrete mixes tailored to project specifications. The plant consists of several key components such as material storage bins, a weighing system, a batching plant and a mixing unit. JEL Manufacturing’s concrete plants are specially designed to produce high-quality ready-mix concrete efficiently and consistently.
Types of Concrete Batch Plants
Concrete batch plants vary in configuration based on project needs like size, location and production volumes. Key types include ready-mix plants used to mix concrete for truck mixer delivery, central-mix plants used to combine concrete before truck loading, portable mobile plants for job site flexibility and high-capacity stationary plants for large-scale operations. The appropriate plant selection impacts efficiency and costs, optimizing output based on application requirements.
Ready-Mix Concrete Plants
Ready-mix plants partially mix concrete ingredients and load the plastic concrete into truck mixer drums. Concrete is mixed during transit to the job site, catering to a diverse geographic location. Ready-mix plants offer flexibility for varying mix designs and volumes. They are common for midsize to large construction projects. Mixer trucks continuously agitate the concrete to keep it workable.
Central Mix Concrete Plants
Central mix plants fully combine and mix all concrete ingredients before transferring them to non-agitating truck bodies. The concrete arrives in a mixed plastic state. Central mix plants require less truck equipment but have higher startup costs to operate. A central mix plant is ideal for large, continuous pours on a single site because adjustments are more difficult compared to ready-mix plants. Central mix plants maximize efficiency by eliminating truck mixer wear and tear.
Mobile Concrete Plants
Mobile batch plants are compact and mounted on truck trailers or portable containers. The self-erecting plant can be easily moved between multiple job sites. Mobile plants eliminate long travel distances for remote project locations and are cost-effective for small-scale projects. However, mobile plants have lower production capacities than stationary plants.
Common Mobile Concrete Plant Types
Stationary Concrete Plants
Stationary plants are permanently installed facilities built for high-volume concrete production. Their larger equipment and material storage allow continuous batching and mixing. Stationary plants require significant upfront capital investment but offer the lowest operating costs long-term. They supply ready-mix or central-mixed concrete depending on plant design. Stationary plants are Ideal for large infrastructure projects or plants servicing an entire region.
Common Stationary Concrete Plant Types

Common Concrete Plant Components
Concrete Mixers
Concrete mixers are machines used to combine cement, water, aggregates (sand and gravel) and admixtures to produce concrete. They ensure a homogeneous mixture by continuously agitating the materials during the mixing process.
Hot Water Tanks
Hot water tanks, also known as water heaters, are storage tanks used to heat and store hot water for various applications, such as residential or commercial use, providing a ready supply of hot water on demand.
Aggregate Feed Systems
Aggregate feed systems are designed to transport and deliver aggregates (sand, gravel or crushed stone) from storage areas to mixers or other processing equipment in concrete production facilities or quarries.
Control Systems
Control systems monitor and regulate various processes and equipment in a concrete production facility, ensuring efficient operation, product quality and safety compliance.
Dust Collection
Dust collection systems are essential in concrete production facilities to capture and remove particulate matter, such as cement dust, from the air, improving air quality and reducing potential health hazards for workers.
Silos
Silos are tall, cylindrical structures used for the bulk storage of powdered or granular materials, such as cement or aggregates, in concrete production facilities or other industrial settings.
Conveyors
Conveyors are mechanical systems used to transport materials horizontally or at an incline over short or long distances, playing a crucial role in moving aggregates, cement and other materials within concrete production facilities.
Bins & Hoppers
Bins and hoppers are storage containers used to hold and dispense bulk materials, such as aggregates or cement, in concrete production facilities, acting as intermediate storage points or feeding mechanisms for various processes.
How a Concrete Plant Functions
A concrete plant is loaded with all of the ingredients used to make the exact mixture you're after. The concrete plant then dispenses each material needed in the portions requested by the concrete plant operator. Normally, each material is weighed on a huge scale before being placed into a conveyor or dumped into a mixer or truck, where the materials are mixed into wet concrete and become ready to use.
How is a Concrete Plant Loaded?
Usually with a front end loader. Some people will build a tall ramp to fill their concrete plant directly with the front-end loader and others will use a feed system to feed the concrete plant. Normally if a concrete plant has a feed system they will still have a front end loader filling the feed systems, but some plants use Drive Over Truck Grizzlies to deliver materials directly into a pit where they can be conveyed to the concrete plant automatically without the need for a front end loader.
Do All Concrete Plants Work the Same?
No. Most concrete plants weigh each material, but some use the volume of material. Some concrete plants drop materials into a scale until the weight is correct, while another type of concrete plant will dispense material from a scale until the weight is right. Some concrete plants have all the materials stored above the point of discharge and other plants convey materials using conveyors, augers or another method to the point of discharge.
Advantages of Using a Concrete Plant vs Traditional Methods
Using a concrete plant offers several advantages over traditional methods of concrete production. Concrete plants provide a controlled environment for mixing, ensuring consistent quality and accurate proportioning of materials. This level of precision is difficult to achieve with manual mixing methods. Concrete plants are highly efficient, capable of producing large volumes of concrete quickly, making them ideal for large-scale construction projects.
Automated systems reduce the need for manual labor, minimizing the risk of human error and improving overall productivity. Concrete plants often incorporate recycling mechanisms, allowing excess concrete reuse and reducing waste, contributing to a more sustainable construction process.
Industry Applications of Concrete Plants
Concrete plants are versatile and find applications across various industries. In the construction sector, they are essential for supplying concrete to numerous projects, ranging from residential and commercial buildings to infrastructure developments such as bridges, roads and dams. The mining industry also relies on concrete plants for the construction of mine shafts, support structures and other facilities.
Concrete plants play a crucial role in the precast concrete industry, providing the necessary materials for manufacturing precast components like beams, columns and panels. Other industries utilizing concrete factories are the energy sector (for building power plants and infrastructure related to renewable energy), and agriculture (for building silos and storage facilities).
Average Cost of Concrete Plants
The cost of a concrete plant depends on several factors, such as the type of plant (stationary or mobile), production capacity, level of automation and additional features. Generally, a small to medium-sized stationary concrete plant can cost anywhere from $200,000 to $1 million. Larger plants with higher production capacities and advanced automation systems cost several million dollars. Mobile concrete plants, which offer the advantage of portability and flexibility, typically range from $500,000 to $2 million.
Costs fluctuate based on factors such as location, equipment supplier and specific project requirements. To calculate what your potential return on investment would be with given concrete plant parameters, request our concrete plant ROI calculator.
How to Make Money with a Concrete Plant
Operating a concrete plant can be a lucrative business venture, offering multiple revenue streams. The primary source of income is the sale of ready-mix concrete to construction companies, contractors and developers. Concrete plants generate revenue by offering services such as concrete pumping, delivery and on-site mixing.
Another potential revenue stream is the sale of excess or recycled concrete materials to other manufacturers or construction projects. Diversifying into related services by renting equipment or providing consulting services, can further enhance profitability. Successful concrete plant operations require strategic location, efficient management and a strong understanding of market demand and pricing dynamics.
Reasons to Buy a Concrete Plant
Ready-mix companies operate a concrete plant exclusively to sell their concrete for profit to people and companies. Construction businesses buy concrete factories to save money and receive better delivery than local concrete suppliers. Precast companies buy concrete plants because they use concrete every day, and it is cheaper and more efficient to make the concrete they need with a concrete plant than try to do it by hand or buy it from another company.
