Diesel Engine Twin Shaft Concrete Mixer
The diesel engine twin-shaft concrete mixer uses a diesel engine as its power source and delivers reliable mixing performance in various working conditions. As a result, it is widely applied in construction sites, road works, bridge projects, and other concrete production scenarios.
Moreover, this mixer performs especially well in areas with inconvenient or unstable power supply. By adopting two parallel horizontal mixing shafts, it actively drives the blades to mix materials, ensuring fast and uniform concrete blending.
In addition, its robust structure, flexible operation, and high production efficiency make it a practical and efficient solution for on-site concrete mixing.

Structure
Mixing Device
The mixer adopts two parallel twin shafts equipped with mixing blades. The blades follow a spiral arrangement, which actively pushes and circulates materials to achieve thorough and uniform concrete mixing.
At the same time, the mixing blades use wear-resistant materials, allowing the mixer to maintain stable performance even after long-term operation.
Power System
The diesel engine provides strong and reliable power for the mixer. Typically, it uses a four-stroke or two-stroke design, enabling quick start-up and high torque output.
Meanwhile, the transmission system efficiently transfers power from the diesel engine to the mixing shafts through belt drive or gear drive, ensuring smooth operation.
Frame and Shell
The frame supports the entire mixer structure and uses high-strength welded steel, which ensures excellent rigidity and overall stability.
In addition, the outer shell encloses the mixing device and power system. It adopts wear-resistant steel plates and internal liners to effectively reduce material wear.
Feeding and Discharging System
The feeding system introduces concrete materials through a feed hopper and feed gate, ensuring smooth and controlled loading.
After mixing, the discharge system releases the finished concrete through a discharge gate, often assisted by a conveying device for higher efficiency.
Control System
The control panel allows operators to manage start-up, shutdown, and speed adjustment with ease. Indicator lights and control buttons provide clear operational feedback.
Furthermore, built-in sensors continuously monitor parameters such as temperature, pressure, and speed to ensure safe and stable equipment operation.
Cooling System
The radiator dissipates heat from the diesel engine using either air cooling or water cooling methods.
At the same time, the cooling fan enhances airflow, ensuring reliable engine performance even in high-temperature working environments.
Working principle
First, the diesel engine starts and supplies stable power to the mixer. Next, concrete materials enter the mixing chamber through the feed port.
Then, the transmission system transfers power from the diesel engine to the mixing shafts, causing them to rotate continuously. As a result, the mixing blades push the materials toward the center of the shafts while simultaneously applying shearing, extrusion, and flipping actions to achieve thorough and uniform mixing.
Finally, the fully mixed concrete discharges through the outlet and is transported directly to the construction site for use.
