In modern construction, the quality of concrete and the efficiency of the process are crucial to the success of a construction project. The self loading concrete mixer, as a modern construction tool, is increasingly becoming essential on job sites due to its high level of automation and intelligence. It not only streamlines the processes of concrete production and transportation but also significantly enhances construction efficiency and safety.
However, do you know how the self loading concrete mixer works? Next, I will provide you with a detailed explanation of it, covering everything from the steps of loading and mixing to transportation and discharge. These steps will help you gain a comprehensive understanding of its operation.
Step 1: Loading Materials
Loading is the first critical step of the self loading concrete mixer working. It determines the efficiency and quality of the subsequent concrete production. The loading process involves several key components, including the loading bucket, lifting device, and discharge system.
First, load the raw materials such as sand and gravel through the bucket. The bucket is equipped with specialized wear-resistant teeth designed for loading 50-ton vehicles. It has a wear-resistant plate installed on the bottom, which greatly extends the bucket’s service life.
Next, lift the aggregate to the entrance of the mixing drum via the loading bucket lifting device. This device is typically driven by an electric motor and powered by a hydraulic system to provide the necessary lifting force.
Finally, the bucket’s discharge system comes into play. Discharge the materials automatically from the bucket and accurately transport into the mixing drum.
Step2: Weighing and Batching Materials
Weighing and batching are crucial steps to ensure the accuracy of concrete mix formulations. The step involves precise weighing and batching of raw materials to guarantee the desired properties of the concrete.
Weighing Process
The self loading mixer features high-precision weighing sensors, typically installed in the loading bucket, mixing drum, and other key components.
During the loading process, the weighing sensors continuously monitor the weight of the raw materials. For instance, when the bucket loads aggregates (sand and gravel), the sensors measure the weight in real time and transmit the data to the control system. The system compares the actual weight data with the bucket’s load amount. If there is any discrepancy, the operator can adjust the amount of aggregate in the bucket to ensure accurate batching.
AIMIX proudly maintains a weighing system error of just 2%, and the water addition system error is only 2.4%, the lowest weighing error in the industry.
Batching Process
In addition, we have upgraded our self loading mixers with advanced, large-screen displays that clearly show the batching and weighing system information.
The self loading concrete mixer truck operators input or select the concrete mix recipe through the control panel. The recipe includes the weight ratios of each material, such as cement, aggregates, water, and additives. The control system automatically adjusts the quantities of materials based on these settings.
Additionally, the control system records all data during the batching process, including the actual weights of each material, the batching ratios, and the batching times. This data helps track the production process and ensures that each batch of concrete meets the required standards.
Step3: Mixing The Materials
If you finish the loading, weighing, and batching process, the next step is to blend the materials. The mixing process is the core process of concrete mixture production. It can directly affect the quality and performance of the concrete mixture.
Start Mixing: When starting the mixing process, an electric motor drives the mixing blades inside the drum to begin rotating. The blades rotate at a set speed, thoroughly mixing the concrete. During the mixing process, the angle of the drum may also be fine-tuned to ensure uniform mixing of the concrete.
Mixing time: Additionally, carefully control the mixing time. Set the mixing time on the control panel according to the recipe. Excessive mixing time may lead to over-mixing of the concrete, which can affect its strength and workability. Conversely, insufficient mixing time may result in uneven mixing of the concrete.
Step4: Transporting
The transportation process refers to transporting the mixed concrete from the self loading mixer machine to the construction site. The efficiency of this step directly impacts the progress of the construction.
Keep Drum Rotating During Transporting
When transporting the concrete mixture, it is necessary to keep the mixing drum in a flowing state during transportation.
The rotation of the mixing drum ensures that the concrete remains evenly mixed during transportation. During this phase, the drum rotates at a slow speed, which helps maintain the consistency and flowability of the concrete.
Step5: Discharging The Concrete Mixture
When the self loading mixer truck arrives at the construction site, it is time to discharge the concrete mixture. During this process, pay attention to the fluidity and control of the concrete.
- Discharge System: The self loading concrete mixers are typically equipped with an automatic discharge system, including a discharge chute and hydraulic control devices. The system can ensure that concrete can be smoothly discharged from the mixing drum.
- Discharge Process: During the discharge process, adjust the mixing drum of the self loading concrete mixer truck to the appropriate angle. Besides, the hydraulic system controls the opening and closing of the discharge chute. The operator can adjust the discharge speed through the control system to ensure a smooth flow of concrete.
- Discharge Control: To ensure construction quality, the discharge process requires precise control of the concrete flow rate and discharge speed. The control system of the self loading concrete mixer continuously monitors and adjusts these parameters in real time to prevent issues during the discharge process.
Control The Working of Self Loading Concrete Mixer
The control system is the “brain” of the self loading concrete mixer truck. It is responsible for controlling all the above 5 steps, including loading, weighing and batching, mixing, transporting, and discharging. The operator in the cab can control the mixer through the handle operation and the screen operation .
The control system can monitor and adjust various parameters of the mixing process in real-time, such as feeding amount, mixing time and speed. In addition, it also collects data through sensors and operates according to the preset program to ensure that every operation can be executed accurately.
Advantages of Self Loading Mixer Control System
Improve Production Efficiency
Through the automation and intelligent control system, the self loading mixer for sale can greatly improve production efficiency. The automatic loading and mixing functions reduce the time and labor of manual operation. It can complete the entire concrete production process, which improves the construction progress.
Ensure Concrete Quality
The high precision and stability of the control system ensure the consistency of the quality of each concrete mixing. By accurately controlling the material ratio and mixing time, the strength and uniformity of the concrete are guaranteed, meeting the high standards of construction.
