open-bodied dump truck. Dry mix plants differ from wet mix plants in that wet mix plants contain a central mixer, which can offer a more consistent mixture in a shorter time (generally 5 minutes or less). 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. Certain plants combine both dry and wet characteristics for increased production or for seasonality. For example, a
373:, also named PC component, is a concrete product that is processed in a standardized process in the factory. Compared with cast-in-place concrete, precast concrete can be produced, poured and cured in batches. A precast concrete batching plant has a safer construction environment, lower cost, and high quality products compared with concrete poured on site; the construction speed can be guaranteed. In addition, it is widely used in transportation, construction, water conservancy and other fields.
212:, and there are many types of mixers, such as tilt drum, pan, planetary, single shaft and twin shaft. The twin shaft mixer can ensure an even mixture of concrete through the use of high horsepower motors, while the tilt mixer offers a comparatively large batch of concrete mix. In North America, the predominant central mixer type is a tilt drum style, while in Europe and other parts of the world, a twin shaft mixer is more prevalent. A pan or planetary mixer is more common at a precast plant.

A ready mix concrete plant is generally located inside the city, transporting ready-mixed concrete for projects through concrete truck mixers. Ready mix concrete plants have higher requirements for durability, reliability, safety and environmental protection of the concrete plant's system than other types of plant.

loading point is a large emission point for dust pollution, so many concrete producers use central dust collectors to contain this dust. Notably, many transit mix (dry loading) plants create significantly more dust pollution than central mix plants due to the nature of the batching process. A final source of concern for many municipalities is the presence of extensive water runoff and reuse for water spilled on a producer's sites.
