What Is Concrete Batching Plant

Concrete batching plant, also called briefly batch plant or batching plant, is a construction applied equipment that mixes concrete. It used to combine coarse aggregates, sand, cement, and other admixture to produce homogenous concrete. The final mixture can be widely used to construct skyscrapers, sidewalks, bridges, houses, highways, airports. etc. The plants can be used wet or dry, and come in a variety of configurations and production types

Batching plant capacity ranges from 25m³/h to 240m³/h, largely depending on the types of concrete batch plants and concrete batching plant design. For instance, The size of stationary batching plants is commonly larger than that of mobile ones.

How Does A Concrete Batching Plant Work

Concrete batching plant is a kind of combined device, mainly composed of main building structure, mixer, powder silo, screw conveyor, belt conveyor, weighing system, liquid supply system, gas supply system, electric control system, dust removal device, batching station, control room, used for centralized production of concrete.

Despite the difference in the size of the stationary concrete batching plants and the mobile ones, both have the same working principle.

Batching Plant Operation Procedure

1. Load the aggregates like gravel and sand into individual storage bins, and after being weighed individually, they will be dispatched to the feeding belt conveyor, which then convey them to the weighing hopper on the top of the concrete mixer.
2. Under the control of the control system, the cement is transported to the weighing hopper by the screw conveyor; the water and additives are also transferred to their respective weighing hoppers.
3. Open the pneumatic door of the weighing hoppers; open the pneumatic butterfly valve of the cement weighing hopper, fly ash weighing hopper, and the water weighing hopper; Open the pneumatic ball valve of the additive weighing hopper.
4. Turn on all the weighing hopper vibrators and water inlet pressure pumps to make all materials enter the concrete mixer to blend evenly.
5. Once the setting time is over, the mixer will discharge the mix into a transit mixer or a concrete pump.

Please keep in mind that commonly the concrete must be prepared, transported, and then applied between 30-45 minutes, which is also known as preparatory setting time, concrete must not segregate in the whole course.

Advantages of Concrete Batching Plants

Preparing ready mix concrete on the construction site is a time-consuming process. You can eliminate your construction cost by using a batching plant for your project. Each load of concrete is produced on-site. The production and delivery are done in minutes when we use a concrete batching plant. Adjust your concrete production as per the requirements and get the most out of it. There are several benefits that the concrete batching plant has to offer to construction workers:

Mixing raw materials with stable, advanced production technology, using computer control, accurate measurement, testing means complete, stable and reliable quality, rich high strength, thus greatly improving the construction quality level building (structure).
Construction units use commercial mixing stations, the construction speed increases, reducing equipment, racks, pipes, templates and other turnover rental costs; owners of units can shorten the construction cycle, reduce investment risk.
Due to the stable and reliable quality of the commercial mixing plant, the design unit can avoid the “fat beam”, “fat column” and “heavy plate” according to the design of the mixing station”. The mix mixing station using mineral active admixtures (slag and fly ash and admixture, etc.) can greatly improve the long-term performance of concrete waterproof, antifreeze, anti cracking and abrasion resistance, and can improve the service life of a building.
Improves the construction organization, reduces labor intensity, reduces construction management costs, technical difficulty and quality risk.

Batching Plant Inspection Checklist

How to check the quality of the concrete batch plant, what should be paid attention to before the first use of your concrete plant, the answers to these critical questions are summed up by us as follows.

1. Inspect the quality of the steel bars, the size of the mesh, and the accuracy of the screening when it comes to vibrating screen.
2. To see whether the work of the transmission system is active and whether there is any abnormal noise.
3. The transmission of belt conveyors, bucket elevators, and cantilever drag shovel should be stable, with no abnormal noise, no jamming.
4. Examine the flexibility and accuracy of the measurement system.
5. Observe whether the rate of temperature rise of the reducer is aligned with the qualification certificate or not.
6. Material's In and out through the measuring hopper should be smooth, with no signs of accumulation, overflow, etc.
7. The safety valve cannot show air leakage.
8. Check whether the quality of the cement tank is qualified.
9. The circuit equipment should be reasonable and accurate.

Mobile batching plants can be transported to the site, set up quickly, and start producing concrete, saving time and resources.
  • How does a concrete batching plant ensure consistent quality in the produced concrete?
    Concrete mixing plants ensure consistent quality by automating the measurement and mixing processes. The advanced control systems closely monitor ingredient proportions, mixing times, and other parameters, reducing human error and variations. This precision guarantees that each batch of concrete meets the desired strength, durability, and other performance criteria.
  • What safety measures are in place within a batching plant?
    concrete batching plants prioritize safety through various measures. These include safety guards on moving parts, emergency stop buttons, proper ventilation systems to mitigate dust and fumes, and employee training on plant operation and safety protocols. Occupational health and safety standards are upheld to ensure a secure working environment for plant operators and personnel.
  • Can a batching plant be integrated with other construction equipment?
    Yes, concrete mixing plants can be integrated with other construction equipment, such as concrete pumps, mixers, and conveyors, to streamline the construction process. The integration allows for the seamless transfer of freshly mixed concrete to the construction site, enhancing efficiency and reducing manual handling.
  • How does a concrete batching plant contribute to project scheduling and timelines?
    concrete batching plants play a crucial role in project scheduling by providing a consistent and reliable supply of concrete. With precise control over production, construction businesses can better plan and manage their concrete requirements, minimizing delays and ensuring timely project completion.
