Concrete
Anyone in the construction business knows the importance of concrete. No wonder this composite material is used to construct skyscrapers, sidewalks and bridges, houses and driveways, highways, and many other things around the world. After being set and formed, concrete acts as a durable material strong enough to hold up against some of the largest natural forces. Yet, concrete is “plastic” in that it can be formed and moulded into virtually any shape before it is hardened. When it does harden, the quality of the concrete depends upon its properties as a mixture.
Concrete Manufacturing Plants
A concrete manufacturing plant, also known as a concrete batching plant, comprises all the equipment, mechanisms & processes used to combine the various ingredients to make concrete. A concrete batching plant has many components to it. It is the assembly of tools & machines such as mixers, cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, air systems & control. Concrete can be mixed to a customer’s specific requirements & is sold & bought by volume.
Types of Concrete Batch Plants
Normally, a concrete batch plant can be of two types, depending upon how the mixing is done & when the concrete reaches the job site.
-
The first is a dry-mix plant, which involves combining all ingredients for the concrete except for water, which is added as the final ingredient during transportation to a job site. Dry-mix plants are the predominant type in South Australia.
-
A central-mix batch plant is another type & combines all ingredients for the concrete, including water, & then transported to the job site.
​Dry-Mix Batch Plants
The dry mix concrete plant is a special-purpose concrete batch plant, which is mainly used for projects with lower concrete quality requirements & long distances to transport. The dry concrete mixing plant is not equipped with a central mixer & the concrete is stirred by the concrete agitator truck during transportation. When the dry concrete mixing plant works, each system feeds the weighed aggregate, cement, fly ash, etc. into the storage hopper, then loads the material into a loading hopper from the storage hopper. Next, the batch controller organises to load it into the concrete agitator truck with water & other additives. The concrete agitator truck controls the rotation of the tank at a reasonable speed of to achieve the purpose of mixing.
Concrete Manufacturing Plant Maintenance
Marleston can provide a full inspection of a concrete batching plant with a report provided on the condition of the various components and repairs/maintenance foreseeable and required.
The aspects of the inspection can include the condition of all the bins, rails, gates, chutes, air rams, air lines, scales, socks, solenoid valves & vibrators. The conveyor systems are also reviewed including the condition of the take up, belts, guards, rollers, skirtings, bearings. Filter checks, safety valve checks & probe functioning checks of silos are also undertaken.
Marleston provides a comprehensive maintenance and repair program of all aspects of the concrete batching plant. Whether it be supplying and fitting loading socks, welding repairs to bins through to the fabrication of acid sheds or batch control rooms, we provide an expert and reliable service.
