About dry and wet concrete batch plants, there is bound to be someone who has some misunderstanding about them, so this article will summarize some introductions about dry and wet batch plant for your reference.
Concrete Batch Plant is used to combine sand or gravel, water, air, admixtures, fly ash, cement, etc. to produce concrete. There are two main types of concrete plants: Dry and Wet batch plants, and also plants that contain both a transit mix side and a central mix side while utilizing common material storage points.
Dry mix Concrete Plant/Transit Mix Plant uses the digital or manual scales to weigh sand, gravel and cement in weigh batchers. After this step, they will be discharged into a chute which discharges into a truck. Meanwhile, water is also being weighed or volumetrically metered and discharged through the same charging chute into the mixer truck. All materials are then mixed for a minimum of 70 to 100 revolutions during transportation to the job site.
Wet mix Concrete Plant puts some or all of the above materials including water into a concrete mixer at a central location. After the mixing process, the concrete can be discharged into a mixer truck or agitor to transport concrete to the construction site. What should pay more attention is during the transportation process, the agitor or the mixer truck should rotate at an appropriate speed in case the concrete solidifying.
To sum up, the difference between Dry mix and Wet mix plants is that Wet Mix plants contain a central mixer to produce a more consistent mixture within short mixing time. Dry mix plants typically see more break strength standard deviation and variation from load to load because of inconsistencies in mix times, truck blade and drum conditions, traffic conditions, etc. With a Central Mix plant, all loads see the same mixing action and there is an initial quality control point when discharging from the central mixer.
