How To Operate Concrete Batching Plant

 The operation of a concrete batching plant is a complex process involving several steps and details, which can be mainly divided into the preparation stage, the charging stage, the mixing stage, the transportation stage and the unloading stage.


The following is a detailed description of these stages:
1. Preparation stage
- System energization and inspection:
After the automatic control system of the concrete mixer is energized, it enters into the operation page.
Carry out a series of inspections, including no foreign matter stuck in the mixing cylinder and the transmission and movement parts of each supporting mechanism as well as the bin door, bucket door and track, etc., the oil level of each lubricating oil tank is in accordance with the regulations, as well as each electrical device can effectively control the mechanical action.
- Reset and recipe settings:
The system software carries out the reset solution, which mainly includes the setting of formula standard, concrete grade, caving degree, and production and manufacturing square volume.

2. Charging stage
- Raw material weighing and measurement:
Based on the weighing of the hopper, measurement to carry out inspection, export empty or full of material data signal, prompting the operating staff to run the mixing management program.
Run the sand, stone drive belt drum motor into the pre-materials to the measurement hopper, open the coal ash, cement silo disc valve, run the screw machine motor to transport coal ash, cement to the measurement and verification hopper.
Open the regulator valve of the water and concrete admixture tank to allow water and concrete admixture to be injected into the metering and checking hopper.
- Open the feeding port:
Open the door of metering and checking hopper after the measurement reaches the setting regulations, and the ingredients enter into the already running mixer.

3. Mixing stage
Inside the concrete mixer, the raw materials are mixed with water, and fully mixed and crushed through the high-speed rotating mixing blades to make the concrete uniform and consistent.
During the mixing process, it is necessary to pay attention to whether there are people in the mixer and on the conveyor belt, and when there are people, operation is prohibited.

4. Transportation stage
While mixing, the concrete mixer conveys the mixed concrete into the concrete transportation truck so that the concrete can be transported to the site.

5. Unloading Stage
After transporting the concrete transporter to the construction site, the concrete is discharged from the vehicle through the hydraulic discharging system.

6. Shutdown and cleaning
Before the concrete mixer stops, it should be unloaded first, and then close the switches and pipelines of each ministry in order. All the cement in the spiral pipe should be conveyed out, and no material should be left in the pipe.
After operation, the mixing cylinder, discharge door and discharge hopper should be cleaned and flushed with water, and the additives and their supply system should be flushed at the same time. The knife seat and knife edge of the weighing system should be cleaned and the weighing accuracy should be ensured.

7. Precautions
- Safe operation:
After starting the machinery, carefully check the operation of the machinery and check whether the rotation direction of each rotating part is consistent with the direction of the marked arrow.
No repair, maintenance, lubrication, fastening and other operations can be carried out during the operation of the machinery. It is prohibited to put hands and feet near the gate, mixing drum, spiral pipe, etc.
- Troubleshooting:
No shutdown is allowed when mixing with full load, when fault or power failure occurs, immediately cut off the power supply, lock the switch box, remove the concrete in the mixing drum, and then troubleshoot or wait for the power supply to be restored.
- Training and examination:
The mixer operator shall undergo study and training to understand the structure and performance of the mixing system and operation work procedure of the unit, familiarize with the safety operation and technical specifications, familiarize with the basic operation of the computer, and basically understand the quality requirements of concrete and the main properties, specifications and roles of the raw materials, and shall only be allowed to operate after passing the actual examination of the parent company.

Through the above steps and precautions, you can ensure the safe and efficient operation of the concrete batching plant.
