Dry batch concrete plants differ from wet mix plants in many ways. Dry mix plants are also called ‘truck-mixed’ or ‘dry-batched concrete manufacturing’ that requires all raw ingredients to be directly discharged into a truck mixer without the need for previous mixing. Dry mix concrete plant is simpler and more cost-effective, but both offer the advantages of high production as well as fast installation and dismantling.
The Differences between Dry Batch and Wet Batch Concrete Plants
Basically, both types are used to produce concrete for construction purposes but a wet concrete batch plant uses a mixing engine and a twin-shaft paddle mixer as a console to produce concrete on its own while a dry type makes use of a concrete mixer truck. Below are the key aspects in which these two concrete plants differ:
Compared with a wet batching plant a dry batch plant is compact and simpler in design and uses less equipment.
A wet batch concrete plant has a twin-shaft concrete mixing engine while a dry batch mixer has none.
A dry batch concrete mixing plant consists of a batching machine; a belt conveyor; storage silos, and a frame in a compact structure.
There are two types of wet batch concrete plants:
Both of these are composed of an aggregate batching machine, a weighing system, twin-shaft concrete mixer, screw conveyor, and cement silos. The difference is that with a skip hoist batching plant the aggregates are lifted directly onto the twin-shaft mixer by a hopper while with a belt conveyor type, aggregates are proportioned and conveyed to a warehouse to await later mixing. The most important difference is that a belt conveyor can produce higher quality concrete from raw materials and is therefore much more environmentally friendly.
Dry batch concrete plants are more suitable for construction projects that require large amounts of concrete material of general quality such as electric power projects, water resource projects, highways, bridges, harbors, airports, commercial concrete plants, and large pre-cast product plants. It has no mixing engine and is actually a concrete batching machine that is used to batch aggregates and convey it to a storage silo to await discharge into a concrete mixing truck to transport to the site.
A wet batch plant uses a mixing engine and has a wide range of applications for medium-scale construction sites, commercial production plants, pre-fabricated plants, and many other construction projects. The quality of concrete produced by a wet batch concrete plant is very high.
Dry batch plant advantages include high efficiency, the stability of performance, and convenient operation. In addition, it can be customized to suit different applications. It always makes use of a concrete mixing truck. When the concrete dosing has been completed, the aggregate is discharged into the feeding chute of a self loading concrete mixing truck. The water supply system of the tuck will add the right amount of water to the mixing tank. The concrete is mixed while the truck is traveling on the road to its destination.
Wet batch concrete plants can produce much higher quality concrete by utilizing a plant mixing engine. This plant provides high-quality concrete, reliable performance, long service life, low investment, and high production levels.
