Concrete Batching Plants

Types
There are many classification standards for concrete plants. Concrete Plant can be divided into dry mix plant and wet mixing plant depending on whether a central mixer is used. It can be also divided into stationary concrete plant and mobile concrete plant depending on whether can  be moveable.

Wet mix Concrete Plant
A Wet mix Concrete Plant, combines some or all of the above ingredients (including water) at a central location into a Concrete Mixer - that is, the concrete is mixed at a single point, and then simply agitated on the way to the jobsite to prevent setting (using agitors or ready mix trucks) or hauled to the jobsite in an open-bodied dump truck. Dry mix differ from Wet mix plants in that Wet Mix contain a central mixer whereas dry, 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.A Mobile batch plant can be constructed on a large job site.

Stationary Concrete Plant
The stationary concrete plant is designed for produce high-quality concrete. It has the advantages of large output, high efficiency, high stability and high specification. Stationary Concrete Batching Plant adopts reliable and flexible , it easy to maintenance and owning a low failure rate. It is widely used in various projects such as roads and bridges, ports, tunnels, dams and buildings.

Mobile Concrete Plant
The mobile batch plant, also known as a portable concrete plant is a very productive, reliable and cost effective piece of equipment to produce batches of concrete. It allows the user to batch concrete at most any location then move to another location and batch concrete. Portable plants are the best choice for temporary site projects or even stationary locations where the equipment height is a factor or the required production rate is lower.


Dry mix Concrete Plant
A Dry mix Concrete Plant, also known as Transit Mix Plant, weighs sand, gravel and cement in weigh batchers via digital or manual scales .
All the ingredients then are discharged into a chute which discharges into a truck. Meanwhile, water is either being weighed or volumetrically metered and discharged through the same charging chute into the mixer truck. These ingredients are then mixed for a minimum of 70 to 100 revolutions during transportation to the jobsite.

A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines  various ingredients to form concrete. Some of these inputs include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement. A concrete plant can have a variety of parts and accessories, including: mixers (either tilt  drum or horizontal or in some cases both), cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors.

The heart of the concrete batching plant is the mixer, and there are many types of mixers such as Tilt Drum, Pan, Planetary, Single Shaft and Twin shaft mixer. The twin shaft mixer can ensure an even mixture of concrete through the use of high A Pan or Planetary mixer is more common at a precast plant. Aggregate bins have 2 to 6 compartments for storage of various sand and aggregate (rocks, gravel, etc.) sizes, while cement silos are typically one or two compartments, but at times up to 4
compartments in a single silo. Conveyors are typically between 24-48 inches wide and carry aggregate from the ground hopper to the aggregate bin, as well as from the aggregate batcher to the charge chute.

The aggregate batcher also named as aggregate bins, is used for storage and batch the sand, gravel and crushed stone of the concrete plant. There are also many types of aggregate batchers, but most of them measured aggregate by weighing, some use the weighing hopper, some use the weighing belt.

The cement silos  are an indispensable device in the production of concrete. It mainly stores bulk cement, fly ash, mineral powder and others. There are 3 types of cement silos, bolted cement silos, Horizontal cement silos and integrated cement silos. Integrated cement silos made in factory, it can be used directly. Bolted cement silo bolted for easy installation and removal. Horizontal cement silos have lower requirements on foundations and can be transported by truck or flatbed without disassembly.

The screw conveyor is a machine to transfer the materials from the cement silos to the powder weighing hopper.
Concrete plant use the control system to control the working of the machine. concrete batch plants employ computer aided control to assist in fast and accurate measurement of input constituents or ingredients. With concrete performance so dependent on accurate water measurement, systems often use digital scales for cementitious materials and aggregates, and moisture probes to measure aggregate water content as it enters the aggregate batcher to automatically compensate for the mix design water/cement ratio target. Many producers find moisture probes work well only in sand, and with marginal results on larger sized aggregate.

What is concrete batching plants ?

A concrete batching plant machine mixes various ingredients to make concrete. These materials include water, air, aggregates, cement and fly ash. It consists of a variety of parts and machine mixer units, conveyors, aggregate and cement batchers, cement silos etc. A concrete batching plant is a machine in which ingredients of concrete are mixed and blended homogeneously to obtain concrete of desired strength and quality. The plants can be used wet or dry and has a wide array of configurations and production types including Ready Mix, Precast & Prestressed, Central Mix, and RCC.

Advantages of concrete batching plants

Preparing ready mix concrete on the construction site is a time-consuming process. You can eliminate your construction cost by using a batching plant for your project. Each load of concrete is produced on-site. The production and delivery are done in minutes when we use a concrete batching plant. Adjust your concrete production as per the requirements and get the most out of it. There are several benefits that the concrete batching plant has to offer to construction workers:

  • Mixing raw materials with stable, advanced production technology, using computer control, accurate measurement, testing means complete, stable and reliable quality, rich high strength, thus greatly improving the construction quality level building (structure).
  • Construction units use commercial mixing stations, the construction speed increases, reducing equipment, racks, pipes, templates and other turnover rental costs; owners of units can shorten the construction cycle, reduce investment risk.
  • Due to the stable and reliable quality of the commercial mixing plant, the design unit can avoid the “fat beam”, “fat column” and “heavy plate” according to the design of the mixing station”.
  • The mix mixing station using mineral active admixtures (slag and fly ash and admixture, etc.) can greatly improve the long-term performance of concrete waterproof, antifreeze, anti cracking and abrasion resistance, and can improve the service life of a building.
  • Improves the construction organization, reduces labor intensity, reduces construction management costs, technical difficulty and quality risk.

The main purpose of using a this plant is to produce homogenous and uniform concrete. The plant must produce concrete consistently in batches one after the other in the same proportions. Based on mixers and location there are different types of batching plants available, each of them with features and applications are explained below.

Different types of concrete batching plants

Concrete Batching Plant-Based on Location

Mobile concrete batching plant

Modern mobile plants come with a stable main chassis allowing extreme durability, safe transportation, continuous long-life operation and sensitive weighing by minimizing the vibrations to the scales. All the equipment necessary for the operation of the batch plant is installed on the main chassis and is being transported on it. Water buffer tank, water pump, additive tank and additive pumps along with air compressor come preinstalled on the main chassis. All the equipment is pre-wired and tested. Concrete plants with 2 complete sets of screw conveyors, filters and other silo equipment can be transported with the help of only one single trailer truck. Mobile concrete batching plants come pre-wired with maximum equipment installed to ensure fast installation on site. Typically a standard mobile plant can be installed in 1-2 days. There has also been the development of Containerized concrete batching plants recently. The containerized concrete batch plant is a new type of batching plant. It consists of a mixing system, control system, material storage system, weighing system, conveying system and others. Also, the container mixing plant owns the features such as small footprint, quick installation, convenient transportation and so on. Compared with the traditional concrete plant, the container mixing plant does not need to set the legs and mounting brackets, eliminating basic design and construction.

Stationary concrete batching plant

Stationary Plants are often composed of huge twin shaft mixers that are designed to work at full capability, efficiency and reliability for a variety of large-scale and high-quality concrete production. Stationary concrete production equipment is built to offer maximum rated production capacity and long work hours. The new models are furnished mainly with twin shaft mixers for maximized capacity, the plants are also available with Planetary mixers and batch sizes could be modified. The Stationary Plants are available in various capacities ranging from 30 m3 to 240 m3 per hour of compacted concrete output. In the current Stationary concrete plants, the aggregates are stored in horizontal bins. The gathering conveyor belt runs below the bins where the weighing of aggregates takes place and the aggregates are then discharged onto the charging conveyor. Pneumatically operated gates are provided for discharge of the aggregate onto the gathering conveyor. The material is all weighed accurately and transferred to the twin shaft mixer through a slinger conveyor. The new batching plants also come with the Skip Hoist and Belt arrangement option for mixer loading. The news models can adopt silica dosing and some special additives very easily.
