A Portable Concrete Batch Plant is a mobile, self-contained unit designed to produce concrete at various locations. It combines cement, water, aggregate (sand, gravel, or crushed stone), and any necessary admixtures in a controlled environment to produce high-quality concrete.
The mixing unit, which is the heart of a Small Portable Concrete Batch Plant, can be a drum mixer or a more advanced twin shaft mixer. Drum mixers are typically used in smaller projects to continuously mix materials, while twin shaft mixers reduce mixing time and achieve a more thorough mix.
The cement storage hopper is used to store dry bulk cement. This hopper has enough capacity to produce multiple batches of concrete. The cement weighing hopper receives a preselected amount of cement from the storage hopper and weighs it precisely to ensure an accurate mix ratio.
The aggregate storage hopper stores aggregates such as sand and gravel in this hopper. The aggregate weighing hopper is similar to the cement weighing hopper, which weighs the correct amount of aggregate. A loading conveyor carries the weighed cement and aggregate from their respective hoppers to the top of the mixing drum.
Portable Concrete Batching Plant usually have one or more mixing drums. These drums are usually mounted opposite each other in the plant. A conveyor dumps the cement and aggregates into a loading hopper, which then delivers the materials to the selected mixing drum.
Water and the required admixtures are added to the mixing drum. The water system usually consists of a tank and a pump that delivers water at the appropriate rate. Admixtures are added to improve the concrete’s properties, such as workability, strength, and durability.
Modern Mobile Concrete Plants are equipped with a computerized control system that manages the mixing process, monitors the amounts of ingredients, and ensures compliance with the specified mix design. Operators can interact with the plant through a digital interface, making easy adjustments and monitoring the mix in real time.
Once the concrete is mixed, it is discharged from the drum in the reverse direction. The discharge conveyor transports the finished concrete from the plant to the desired location, such as a concrete pump or transit mixer.
Aggregates are loaded into storage silos using loaders or conveyors. Cement is stored in silos, water and admixtures are loaded into their respective tanks.
The control system determines the required mix design. The materials (aggregates, cement, water, admixtures) are weighed separately according to the specified recipe.
Aggregates are transported from the storage silos to the mixing unit. Cement is transported by screw conveyor, water and admixtures are metered into the Portable Concrete Plant mixer.
In the mixer, all materials are thoroughly mixed to form a homogeneous concrete mixture. The mixing time depends on the type of concrete and its application.
Work typically includes quality checks during the mixing process, such as slump testing to measure workability and consistency. If the concrete doesn’t meet specifications, adjustments can be made on-site, such as adding water or aggregate to get the right consistency.
Small Concrete Batch Plants enable on-demand concrete production, minimizing waste and transportation costs while increasing productivity. Their simple yet effective process ensures high quality concrete at every construction site.
