Twin Shaft Concrete Mixer

Introduction of Twin Shaft Concrete Mixer

There are 3 common types of stationary concrete mixers: twin-shaft compulsory mixers, drum mixers and planetary mixers.

JS500 Concrete Mixer

How does Twin Shaft Concrete Mixer Work 
The twin-shaft compulsory concrete mixer has always been the preferred choice for the main machine used to produce standard commercial concrete, It adopts a double-shaft design, with a set of mixing blades installed on the shaft. The blades are staggered front, back, and up and down to form a multi-angle mixing track. The mixer machine rotates the 2 mixing shafts in opposite directions to make the materials repeatedly tumble, squeeze and mix in the drum, achieving an efficient and uniform mixing effect.

The Twin-shaft Concrete Mixer Feature and Application
The twin-shaft concrete mixer is characterized by high production efficiency, energy saving, environmental protection and mature technology, You can have the same technical and quality level at a reasonable price. The concrete is produced with stable quality under strictly controlled production process. It can meet various strength grades and engineering requirements, making it widely used in automated production lines for large quantities of commercial concrete.

    The shaft end adopts multiple seals, one is a floating mechanical seal, the second is a special concrete dust ring, the third is a special polyurethane seal protection, the fourth is a single oil seal, and the fifth is a floating oil seal. The structure is solid, reliable and durable, without leakage, all seals are easy to disassemble and replace, and are more suitable for various harsh working conditions.
  2. Thick stirring shaft is durable
    In order to ensure the wear resistance of the stirring shaft, our company uses ultra-high chromium wearing parts with a chromium content of ≧ 26%. The stirring shaft has been fundamentally optimized, and the diameter is 50mm thicker than that of the domestic industry. There are high-quality hexagonal stirring shafts with better torsion and bending strength. The hexagonal stirring shaft is more convenient to arrange the stirring arm position in a spiral shape, thereby achieving a better stirring effect.
  3. Hydraulic door opening
    The hydraulic unloading system is equipped with a manual door opening device, which can be opened manually in case of a power outage.
  4. Self-developed motors
    AGICO self-developed motors, using domestic manufacturers' slewing supports, reliable quality. All gears are ground, with low operating noise, high output torque, high stability, suitable for various high-intensity, high-load working conditions.
  5. Consumable parts
    The stirring arm is made of high-strength wear-resistant cast steel with an elliptical design, which reduces material resistance and makes the flow smoother. It is thick and strong, not easy to wear and break, and has a long service life. The liner is thickened and produced by the production line process. The material is high-chromium wear-resistant alloy cast iron, which is wear-resistant and impact-resistant.
