Dry-mixed concrete plants, also known as transporting mixed plants, weighing sand, gravel and cement by digital or manual scales. All the ingredients are then discharged into the chute of the truck. At the same time, the water is weighed or volumetric and discharged into the mixer truck through the same charging chute. And then mix these ingredients at least 70 to 100 revolutions during delivery to the site.
The wet mix concrete plants, mixes some or all of the ingredients in the middle position (including water) into the concrete mixer, mixing the concrete at one point, and then mixing it easily on the road leading to the site to prevent the use (or the use of a processor or a hybrid truck ) Or to the scene of an open dump truck. The dry mix is different from the wet mixed plant because the wet mixture contains a central mixer and is dried, which can provide a more consistent mixture in a shorter time (typically 5 minutes or less). The dry mix plant usually sees more variation in the standard deviation of the breaking strength and from load to load due to the mixing time, truck blades and drum conditions, traffic conditions and so inconsistent. Using a central mixing device, all loads will see the same mixing action when the initial mass control point is removed from the central mixer. Some plants combine dry and wet characteristics to increase yield or seasonal. Le A mobile batch factory can be built on large site. 
Both wet-mix and dry-mixing equipment can be computer-assisted using a batch computer. Different types of concrete batch plant types can be used for a variety of applications.
