Concrete batching plant, also known as concrete mixing plant, is a joint unit used to centralize the mixing of concrete. Concrete batching plant components mainly consists of the following major systems: storage system, measuring system, conveying system, liquid supply system, pneumatic system, mixing system, main building frame, control room, dust removal system, etc. These systems work together to complete the storage, measuring, conveying, mixing and discharging of concrete raw materials.

Specific components of concrete batching plant are:
- Material Storage System
Function: storage of raw materials required for concrete production, such as cement, aggregate (sand, stone, etc.), additives, etc.
Components: powder tanks, pools, aggregate storage silos, aggregate waiting hoppers and additives tanks. These silos are usually made of steel or reinforced concrete structure with sufficient strength and sealing performance to ensure that the materials are not damp, caked or contaminated during the storage process.
- Measuring System
Function: Accurately weighing various materials according to the set proportion to ensure the stable quality of concrete.
Composition: electronic scale, sensor, controller and so on. The system is divided into aggregate weighing, powder (cement and admixture) weighing, water and liquid admixture weighing and other parts. In large-scale concrete batching plant, the independent weighing of each weighing material is mostly adopted to improve the weighing accuracy.
- Conveying System
Function: conveying various materials from the storage system to the mixing host.
Composition:
Aggregate conveying: belt conveyor or bucket elevator is usually adopted to convey aggregate from silo to mixing host.
Powder conveying: the conveying of cement and admixture often adopts screw conveyor and wind trough pneumatic conveying.
Liquid conveying: mainly refers to water and liquid admixture, which is realized through pumps and pipes.
- Liquid Supply System
Function: Provide water and liquid admixture required for mixing concrete.
Composition: including liquid admixture supply system and water supply system. Modern concrete batching plant is usually equipped with environmentally friendly plumbing zero-discharge wastewater treatment system, which is used to filter and classify the wastewater in the concrete batching plant in order to use it for concrete production under certain conditions.
- Pneumatic System
Function: Utilizing pneumatic pressure to drive part of the mechanism in the concrete batching plant.
Components: air compressor, air storage tank, air pipeline, oil-water separator, pneumatic components, etc. Pneumatic drive is characterized by low cost and no pollution.
- Mixing System
Function: Mix the measured sand, cement, water, additives and other raw materials in the mixer to form the finished concrete that reaches the specified strength.
Composition: The mixing machine is the key equipment, usually adopts double horizontal shaft forced mixer. According to the operation mode, it can be divided into cyclic (also known as intermittent) and continuous; according to the mixing principle, it is divided into self-falling and forced. The forced mixer is characterized by high mixing efficiency, good mixing uniformity and strong wear resistance.
- Main Building Frame
Function: Support various equipments and facilities in the concrete batching plant.
Composition: The frame of the main building is steel structure or combination of concrete and steel structure. The roof of the building is used to support the packing materials; the stairs and fence are the walkway for the management personnel to operate; the metering floor supports various metering systems and aggregate hoppers; the lower part of the mixing floor is the passageway for the concrete mixer truck to enter and exit to receive materials.
- Control Room
Function: The core part of the concrete batching plant operation, responsible for the operation control of the whole mixing plant.
Composition: It includes control cabinet, cable, on-site electric components, execution control software, etc. The control system usually adopts PLC programmable control system. The control system usually adopts PLC programmable controller or touch screen control system to realize automation and intelligent control.
- Dust Removal System
Function: Reduce the dust emission in the production process of concrete batching plant to protect the environment.
Composition: It includes three parts: dust removal when measuring and unloading cement and mixing materials, dust removal when bulk cement trucks add materials to powder tanks, and dust removal when inclined belt conveyor steals materials from aggregate aggregate hopper.

The concrete batching plant components is complex and precise, and the systems cooperate with each other to complete the production of concrete. With the continuous progress of science and technology and the increasing environmental protection requirements, the design and manufacture of concrete batching plant is also constantly upgraded and improved to meet the needs of the modern construction industry.
