Concrete batching plants
are divided into
different types. Plants
are generally divided into stationary
concrete batching plants and mobile
concrete batching plants. This is a basic classification that many manufacturers distinguish at
the time of production.
Stationary Concrete Plants
Stationary
concrete plants
are used to supply
concrete to construction sites in large quantities.
This type of plant does not require specific space on
the site to store materials, limiting
the risk of damage. Also, factory-type stationary
concrete plants ensure high-quality
concrete production per requirements without
the risk of material dosage errors.
Besides, factory-type
concrete batching plants carry out various material quality checks throughout
the concrete manufacturing process. On
the o
ther hand,
they involve a delivery time linked to routing by a mixer truck, more accessible access to
the site, and rapid implementation.
Mobile Concrete Plants
Concrete can be manufactured in a
concrete batching plant temporarily installed on
the construction site.
The mobile
concrete plant allows
concrete production on demand, depending on
the progress of
the site. This type of plant assumes sufficient space for its installation and raw materials’ storage (cement, sand, water).
Also, raw materials should be stored in a clean, dry place away from moisture. Indeed, materials such as water and additives should not come into contact with water. Mobile
concrete plants bring toge
ther heavy installations capable of producing up to 35 m³ / hour.
Dry Mix
Concrete Plants
The dry
concrete batching plant uses digital or manual scales to weigh
the various constituents of
concrete. Subsequently,
they
are unloaded in a chute which flows into a truck.
During this time,
the water is also volumetrically weighed or metered and discharged through
the same loading chute in
the mixer truck. All
the materials
are then mixed for at least 70 to 100 turns during transport to
the job site.
Wet Mix
Concrete Plants
The wet
concrete batching plant puts some or all of
the dry mix plant materials;
they add water into a
concrete mixer located at
the center.
The concrete will be unloaded into a mixer truck or agitator for transport to
the construction site after mixing.
In short,
the difference between
the dry mixing installation and
the wet mixing installation is that
the wet installation includes a central mixer to produce a more stable mixture.
The wet mix plant has deviations from breaks and variations from load to load.
With a central mixing installation, all loads have
the same actions.
There is an initial quality control point when unloading from
the central mixer.
