Batching Plant Process Flow Chart

Concrete batching plant is an indispensable and important equipment in modern construction projects. It transforms various raw materials into high-quality concrete through a series of sophisticated processes. In this article, we will provide you with a detailed process flow diagram of a concrete batching plant to help you better understand this complex and efficient production process.

The flow chart of a concrete batching plant shows the complete process from raw material preparation to finished product delivery, which includes several key steps, such as raw material preparation, proportioning design, pre-production inspection and mixing. Each step needs to be operated in strict accordance with the regulations to ensure the quality of concrete.

Analysis of Concrete Batching Plant Process Flow Diagram

Concrete mixing plant process flow chart usually includes the following steps:

1. Aggregate storage and transportation

Raw material aggregates are usually crushed stone, sand, etc., which need to be sent to the concrete mixer through the storage and transportation process. Aggregates can be transported to the concrete batching machine by belt conveyor or bucket elevator.

2. Aggregate Batching

Aggregates need to be batched in a certain proportion, usually through a concrete batching machine to feed different sizes of aggregates into the concrete mixer in the required proportions.

3. Addition of cement and admixtures

Cement and admixtures are important components of concrete and need to be added to the concrete mixer in a certain proportion.

4. Mixing and blending

Aggregate, cement and admixtures are put into the concrete mixer for mixing, and the concrete mixer will evenly mix these raw materials into concrete within a certain period of time.

5. Conveying and discharging

The mixed concrete will be conveyed to the concrete mixer truck or transportation vehicle through the conveying equipment (such as discharging hopper, screw conveyor, etc.), and then transported to the construction site for pouring.

The above is the basic concrete mixing plant flow chart, and there may be some differences between different models and specifications of concrete batching plant. In actual operation, it also needs to be adjusted and optimized according to the specific situation.

Overall Structure of Concrete Batching Plant

Concrete batching plant is a combination device for mixing cement concrete, and its overall structure is usually installed horizontally, including raw material storage device (sand and gravel aggregate, cement, water and admixture storage device), aggregate lifting mechanism, metering mechanism, secondary lifting mechanism for aggregate, concrete mixer, finished product hopper, control room and other auxiliary devices.

Raw material preparation

Raw materials for processing concrete include sand and gravel aggregates, cement, water and admixtures. First, the sand and gravel aggregate is lifted into the aggregate hopper through the lifting equipment. The number of aggregate hoppers is not less than three with a capacity of 2-3 cubic meters. Meanwhile, cement is lifted to the cement silo for backup. 

Aggregate metering device is placed below the aggregate hopper for easy loading. The measured aggregates are lifted into the concrete mixer. Cement is lifted to the cement metering unit through a screw conveyor from the outlet at the bottom of the cement silo. The metered cement is transported directly into the mixer. Water and admixtures are pumped into the concrete mixer from the storage tank by means of a pump. The materials are then controlled to mix uniformly in the concrete mixer to produce concrete. 

Finished product hoppers are placed below the discharge of the mixer for temporary storage between concrete mixer trucks. Once the work of the mixing plant is completed, the final product is unloaded into the concrete mixer trucks and transported to the construction site.

Material conveying and mixing

Different materials are conveyed by different means:

• Aggregates are conveyed through belt conveyors or bucket elevators;

• Cement is conveyed via screw conveyor;

• Water and admixtures are conveyed via their respective pumps.

Mixing process

Once the various materials have been prepared, the key step is the mixing process. Concrete mixers with powerful mixing capacity (e.g. horizontal twin-shaft mixers, vertical-shaft planetary mixers, etc.) mix the various materials well and evenly through the mixing shafts and blades. After about 60-70 seconds, the batch of concrete product is completed.

Control System

In order to automate the above workflow, the engineers have designed an intelligent control system. All of them are preset in the form of digital programs in the industrial computer. Through the functions of automatic monitoring, automatic alarm, automatic compensation and data storage, the control system can realize the production process control and management of the whole concrete batching plant.

Before production, the operator only needs to input the required parameters of concrete proportioning into the human-machine interface of the industrial computer and click the button to realize the complete process automatically.

Through this series of well-designed process flow, the concrete mixing plant is able to efficiently and accurately produce high quality concrete that meets various construction needs. Understanding this process flow diagram not only helps us to understand the concrete production process, but also helps to further optimize and improve the operation efficiency of the mixing plant.

How to adjust and optimize the batching plant process according to the specific situation?

In practice, the adjustment and optimization of concrete batching plant is the key to ensure production efficiency and concrete quality. Here are some specific adjustment and optimization methods:

1. Raw material management

• Aggregate storage and transportation: Ensure the dryness and cleanliness of the aggregate storage warehouse to avoid moisture or contamination of the aggregate. Use efficient conveying equipment, such as belt conveyors or bucket elevators, to ensure fast and smooth transportation of aggregates to the batching plant.

• Cement and Admixture Addition: Regularly inspect cement and admixture storage equipment to ensure that it is well sealed to prevent moisture caking. Use precise dosing equipment to ensure that the amount of cement and admixtures added is accurate.

2. Batching design

• Ratio adjustment: Adjust the concrete ratio according to the specific needs of the construction site and environmental conditions. For example, in hot weather, the amount of water can be increased appropriately or retarder can be used to extend the initial setting time of concrete.

• Test inspection: conduct small sample test before production to ensure that the proportioning design is reasonable and the concrete performance meets the requirements. For unqualified raw materials or products, take timely measures to deal with them.

3. Equipment maintenance

• Regular maintenance: Regularly check and maintain the mixer, conveying equipment, measuring equipment, etc., to ensure that the equipment operates normally. Replace the worn mixing blades and liners in time to avoid affecting the mixing effect.

• Cleaning and Maintenance: Clean the mixer and conveying equipment in time after production every day to prevent concrete residue from curing and affecting the normal operation of the equipment.

4. Intelligent control system

• Automation control: Use intelligent control system to realize the automation control of the production process. Through the preset program, the steps of feeding, measuring, conveying, mixing and unloading of raw materials are automatically completed.

• Real-time monitoring: Through sensors and monitoring systems, real-time monitoring of the operating status of each link, timely detection and treatment of abnormalities. Use data analysis to optimize the production process and improve production efficiency.

5. Environmental Protection

• Dust control: Take effective dust control measures, such as installing dust removal equipment, to reduce dust pollution during aggregate storage and transportation.

• Wastewater treatment: collect and treat wastewater when cleaning equipment and sites to avoid polluting the environment.

6. Training and management

• Employee training: Provide regular training to operators to improve their operating skills and safety awareness. Ensure that the operators are familiar with the use and maintenance methods of the equipment, and are able to deal with emergency situations in production in a timely manner.

• Management optimization: establish a perfect management system, clarify the responsibilities of each position, and ensure the orderly production process. Through performance appraisal and incentive mechanism, improve the enthusiasm and sense of responsibility of employees.

Through the above measures, the production process of the concrete batching plant can be effectively adjusted and optimized to improve the production efficiency, ensure the quality of concrete and meet the needs of the construction site.
