There are two different types of concrete batching plants – ready mix plants and central mix plants. With ready mix plants, all of the ingredients are combined except for the water. The mixing of the dry ingredients takes place at the concrete plant and then it is discharged into a concrete transport truck (ready-mix truck). The water is then added to the dry mixture while it is in the truck on the way to the job site.
The second types of batching plant is the central mix plant. This type of plant combines some of the ingredients or all of the ingredients, including the water, at one location. The final batch of concrete is then taken to the site.
Central mix plants are different from other concrete batch plants because they provide the recipient with a mixture that is much more consistent because of the mixing is done in one central location. Central mix plants also use automation to ensure that the end product is uniform.
How Does Concrete Batching Plants Work?
These plants are divided into several parts. The part is:
– Gravel feeder
– Feed additives
– Feed (cement, bulking agents, fly ash, etc.)
– Water
The feed, water, and additives are stored and stirred in the workflow. When the mixer’s control system is connected to an electrical source, the operation of the machine will appear and the process will begin. This includes concrete slump, the formula number, productivity and grade of concrete.
Every weighing hopper and silo is tested as determined by the weighing system. The control system will provide the output of the signal for the amount of material needed. The operator will then decide whether to start the program or not.
The belt conveyor is then initiated to transport the aggregated so that it can go to the weighing hopper. The valve for the cement tank and the fly ash will need to be opened, and the screw conveyor along with the motor will need to be initiated so they can be transported to the weighing hopper.
After the weight for all of the materials has met the necessary specifications, the weighing hopper’s door will open automatically.
All of the materials will then be mixed in the concrete mixer. After the proper setting time is over, the concrete mixer’s loading door will open and the concrete will flow into the concrete truck.
This is a process that must be observed carefully and followed according to specifications. The concrete cannot separate, and it must also be ready for transport as soon as it is ready. The concrete must also be poured and used within 45 minutes.
Different Models Of Concrete Mixers
The tilt mixer is commonly used for large construction projects, and it is employed by using an Archimedes’ screw. The mixer is then able to lift the ingredients, mix them together and then convey them to the mixer.
The twin shift mixer helps to ensure that there is an even concrete mixture as well as a large output volume.
The other type of mixer is the pan mixer.
Concrete batching plants are used for commercial and construction sites of every size and complexity. Depending on the specifics for your project, you can choose the batching plant that best meets your needs.
