JS500 Twin Shaft Concrete Mixer
The JS500 twin-shaft forced concrete mixer efficiently mixes dry hard concrete, plastic concrete, fluid concrete, and lightweight aggregate concrete. It is widely applied in construction sites, road and bridge projects, water conservancy works, and small to medium-sized concrete component plants.
Thanks to its high mixing efficiency, stable concrete quality, and simple operation, the JS500 delivers reliable performance in daily production. As a result, it has become an ideal and cost-effective solution for small and medium-sized construction projects.

Structure
The JS500 concrete mixer consists of several core systems that work together to ensure efficient, stable, and reliable concrete production.
Mixing System
First, the mixer adopts a double horizontal shaft mixing drum. Inside the drum, spiral mixing blades continuously stir materials, ensuring fast and uniform concrete mixing.
At the same time, the mixing arms and blades, manufactured through a special casting process, offer excellent wear resistance and achieve high mixing homogeneity.
Transmission System
Next, the transmission system uses a self-developed reducer with strong overload resistance, which guarantees smooth and stable power transmission.
In addition, the mixer employs dual motor drives—one for mixing and one for the winch—ensuring efficient and coordinated operation.
Feeding System
Meanwhile, the feeding system features a winch mechanism with a double-limit protection design, enhancing operational safety.
The hopper can be lifted directly above the mixing drum, enabling automatic and efficient material feeding.
Water Supply System
Furthermore, the mixer is equipped with an automatic metering water supply system. With a water supply error of ≤2%, it ensures accurate concrete proportions and consistent quality.
Unloading System
After mixing, the bottom-opening discharge door, controlled hydraulically or pneumatically, allows concrete to unload quickly and cleanly.
Electrical Control System
Finally, the electrical control system integrates short-circuit protection, overload protection, and phase-failure protection, ensuring safe and stable operation throughout the production process.
Working principle
The JS500 concrete mixer adopts a forced mixing mode, and its working process is as follows:
Feeding Stage
First, the hopper lifts cement, sand, gravel, and water into the mixing drum, or operators can feed materials manually as required.
Mixing Stage
Next, the two horizontal mixing shafts rotate in opposite directions. The blades then forcibly shear, push, and blend the materials, ensuring fast and uniform concrete mixing.
Discharging Stage
Finally, once mixing is complete, the bottom discharge door opens automatically, allowing the concrete to be released quickly and efficiently.
Product Advantages
High Mixing Quality
First, the forced mixing mechanism ensures excellent concrete uniformity. As a result, the JS500 mixer performs reliably when handling dry hard concrete, plastic concrete, and lightweight aggregate concrete.
High Production Efficiency
Moreover, the mixer delivers a theoretical productivity of 25 m³/h, which exceeds the efficiency of traditional self-falling mixers by more than 30%, significantly improving construction progress.
Easy Operation
In addition, the JS500 features a high level of automation. Operators can run it independently or combine it with a batching machine to form a simple and efficient concrete mixing station.
Easy Maintenance
Furthermore, advanced shaft-end quadruple sealing technology effectively extends the service life of key components. At the same time, the modular design simplifies maintenance, allowing quick repair and replacement of parts.
Strong Adaptability
Finally, thanks to its versatile design, the JS500 mixer adapts well to various applications, including construction sites, road and bridge projects, and water conservancy works.
