Self-loading concrete mixer combines “automatic loading + accurate mixing + flexible movement” in one, one equipment can complete the whole process of “loading – mixing – discharging”, greatly reducing labour, time and cost, is a concrete production tool for small projects. Today, we will provide you with step-by-step explanation of the working principle of self-loading concrete mixer, and see how it can save you a lot of costs with technology and improve the construction efficiency and quality!
Next, let us delve into the complete operational workflow of a self loading concrete mixer: How does the loading system grasp the materials? How does intelligent weighing ensure precise mixing ratios? How does the mixing drum achieve uniform mixing?
One-Button Start, Automatic Loading
No need to manually co-ordinate loaders, mixers and loaders. The “one-button start + automatic feeding” design of the self-loading mixer completely simplifies the pre-preparation process. It relies on its own bucket to independently complete the grasping, lifting and feeding of sand and gravel aggregates, and seamlessly connects with the subsequent precise weighing, mixing and unloading to form a highly integrated and automated workflow.
One-button startThe operator simply presses the “start” button in the cockpit, and the self-loader control system receives the command and coordinates the hydraulic system and electronic control unit precisely.
Dancing loading armThe front hydraulic loading arm (usually equipped with a large-capacity bucket) is flexibly tilted under the drive of hydraulic cylinders to accurately pick up materials from the aggregate pile.
Intelligent lifting and dumpingThe loading arm, when fully loaded, smoothly lifts up and moves to the top of the inlet of the mixing drum, the hydraulic gate opens accurately, and the sand and gravel aggregates are slid into the drum along the infeed channel.
The whole process is coherent and smooth, without the assistance of additional loading machinery, sand and gravel aggregate feeding can be completed in a single operation, reducing manpower input by more than 70%.
Formulation Management System for Precise Weighing and Proportioning
This step is the key to determine the quality of concrete. The self-loading mixer’s “cylinder measurement and control weighing technology + dynamic algorithm” controls the proportioning error within ±1% through the digital recipe library and dynamic weighing technology. It achieves tenfold greater precision compared to the common 20–30% error margin typically found on the market.
Recipe management
- Hundreds of ratios (e.g. C15-C80 concrete, impermeable/early-strength concrete) are stored, covering key parameters such as water-cement ratio, sand rate, admixture amount, etc. The operator selects the required specification (e.g. “C35”) through the touch screen, and the system automatically retrieves the corresponding formula.
Simultaneous weighing of multiple materials
- Aggregate, powder, water and additives are weighed in separate hoppers for initial weighing; during the process of pouring aggregate into the mixing tank, the sensors sense the weight change in real time and transmit the data to the control system. Once the set value of formula is reached, the system stops feeding immediately to ensure that the final feeding amount is consistent with the formula.
Powerful Mixing, Uniform and Efficient
Uneven mixing is a common quality problem of concrete, Aimix self loading mixer is equipped with “6 spiral 8 paddles” composite mixing device, forming a double mixing mode of “spiral pushing + paddle shearing”, which can finish mixing a tank of concrete in 15 minutes. And it supports “mixing while moving”, which completely solves the problem of concrete segregation during transport.
6 spiral blades
high-speed rotation drives the material to migrate along the axial direction, forming a strong circulation, mixing the aggregate, cement and water quickly.
8 sets of paddles
rotating synchronously with the spiral shaft, generating radial shear force, breaking the cement slurry film on the surface of aggregate and promoting the uniform distribution of fine particles.
Stirring while walking
equipped with hydraulic drive system, when moving (such as transferring or pouring on site), the mixing machine still keeps low speed, avoiding the concrete sinking and mortar floating due to the static concrete.
This ensures that the concrete still maintains good adhesion when it arrives at the site, even under complicated working conditions such as long-distance transport or construction in mountainous areas.
Free Rotation, Precise Unloading
In the last step, the self-loading mixer realises the intelligent discharging of “no dead angle, zero residue, fast discharging” through hydraulic rotation and intelligent control, so that the finished high-quality concrete is accurately and cleanly delivered to the designated position.
270° Hydraulic TurningThe whole mixing tank is mounted on the chassis by the sturdy rotating shaft and large rotating support. The tank is hydraulically driven to achieve 270° horizontal rotation, and can be tilted to a 30° angle to the ground to accelerate concrete flow by gravity.
120° outlet designThe mixing tank discharge opening is designed at 120°, which is conducive to the smooth discharge of materials and is not easy to cause material clogging. This reduces the splashing phenomenon when dropping the material and avoids the waste of material.
Precise positioning of dischargingBy controlling the rotating angle of the tank, the discharging port can be directly and precisely aligned with the pouring place, or directly discharged into the mould or pumping truck hopper.

Multilingual Support – Universal Communication Capability
For equipment targeting international markets, the ability to adapt the operating interface language is paramount. Upon delivery, whether local operators can comprehend and utilise the equipment directly determines its operational efficiency and customer satisfaction.
AIMIX fully recognises this, pioneering the industry with a control system supporting 7 languages via one-touch switching: Chinese, English, Russian, Spanish, French, Portuguese, and Indonesian. Whether your worksite lies in Russia’s frigid regions or Indonesia’s tropical rainforests, local operators can effortlessly master the equipment, achieving truly global, barrier-free operation.
Finally, once you grasp these operational principles, you will possess the discerning eye to judge the quality of any equipment:
Observe feeding:
Is it robust and smooth?
Examine weighing:
Is it precise and stable? What is the error tolerance?
Observe the mixing:
Is it rapid and uniform?
Evaluate the controls:
Are they intelligent and user-friendly?
