Twin Shaft Concrete Mixing Pump
The twin-shaft concrete mixing pump integrates concrete mixing and conveying functions into one efficient machine. As a result, it is widely applied in building construction, bridge projects, road paving, and other engineering works.By accurately mixing cement, sand, gravel, water, and other raw materials according to preset proportions, the equipment produces high-quality concrete. Moreover, the pumping system continuously delivers the mixed concrete to the designated location, enabling efficient and uninterrupted concrete production and transportation.

Structure
First, the mixing system ensures concrete quality and uniformity.
The mixing drum holds the concrete materials and adopts a twin-shaft structure with a wear-resistant internal lining to withstand long-term operation.
At the same time, the twin-shaft mixing device uses two parallel mixing shafts equipped with mixing blades. These shafts rotate synchronously through a gear or chain transmission system, actively driving materials to achieve thorough and uniform mixing.
Next, the conveying system enables continuous concrete transportation.
The concrete pump, which includes the pumping cylinder, piston, and distribution valve, relies on a hydraulic system to convey the mixed concrete smoothly to the designated location.
Meanwhile, the conveying pipeline uses high-strength, wear-resistant materials to ensure reliable and long-distance concrete delivery.
In addition, the power system supplies stable energy for the entire machine.
The engine or motor—typically a diesel engine or electric motor—provides the main driving force.
Moreover, the hydraulic system, consisting of hydraulic pumps, oil tanks, and control valves, supplies power to the pumping mechanism.
Finally, the control system ensures precise and safe operation.
The control panel allows operators to manage start-up, shutdown, and speed adjustment for both mixing and pumping processes through electronic or hydraulic control.
Furthermore, sensors and measuring instruments continuously monitor parameters such as temperature, pressure, and flow rate, ensuring stable performance and operational safety.
Working principle
First, the feeding device delivers raw materials such as cement, sand, gravel, and water into the mixing drum. Next, the twin-shaft mixing system starts rotating, and the mixing blades actively blend the materials to produce uniform concrete. At the same time, the mixer continues stirring the concrete inside the drum to maintain consistent quality and good fluidity.
Then, the mixed concrete flows through the delivery pipe into the pumping cylinder. Meanwhile, the hydraulic system drives the piston to move back and forth, pushing the concrete into the distribution valve. Finally, the distribution valve directs the concrete into the delivery pipeline and transports it smoothly to the designated location.
Product Advantages

The twin-shaft mixing system delivers fast and uniform mixing, which shortens mixing time and increases overall productivity. Moreover, by integrating mixing and pumping functions, the equipment reduces material transfer and handling time, significantly improving construction efficiency.
Excellent Uniformity
The twin-shaft design actively prevents concrete segregation and ensures consistent material distribution, thereby improving overall concrete quality.
Strong Flexibility
With its compact structure and easy mobility, the equipment adapts well to various construction sites. In addition, operators can adjust both mixing and pumping speed and capacity to meet the requirements of different projects.
High Reliability
The machine uses high-strength, wear-resistant materials to ensure long service life. Furthermore, advanced control systems and sensors monitor and adjust the mixing and pumping processes in real time, ensuring stable and reliable operation.
Environmental Protection
Thanks to effective sealing, the equipment minimizes dust emission and operating noise, meeting environmental standards. In addition, integrated dust removal and noise reduction devices further reduce environmental impact.
