JS1000 Twin Shaft Concrete Mixer
JS1000 twin-shaft concrete mixer is a forced concrete mixer suitable for mixing dry hard, plastic, fluid concrete and lightweight aggregate concrete. It is widely used in construction sites, roads and bridges, water conservancy projects and small and medium-sized concrete component plants. This model has the characteristics of high mixing efficiency, stable quality and easy operation, and is an ideal choice for medium-sized projects.

Mixer Motor Power: 37Kw
Voltage: 220v/380v/415v/440v/480v(50Hz/60Hz)
Product Structure
JS1000 twin-shaft concrete mixer is mainly composed of the following core components:
Mixing system
Mixing drum: adopts twin-shaft design, with spiral blades inside to ensure uniform mixing of concrete.
Mixing arm and blades: Made of high-chromium alloy (chromium content ≥ 26%), with strong wear resistance and good mixing homogeneity.
Transmission device:
Reducer: Adopts planetary cycloidal pinwheel reducer, with smooth transmission.
Open gear: drives two mixing shafts to rotate in opposite directions at the same speed.
Feeding system
Winching mechanism: driven by brake motor, the hopper is pulled up along the track by wire rope.
Hopper: After lifting to the top of the mixing drum, the door is automatically opened for feeding, equipped with double limit switches to ensure safety.
Unloading system
Hydraulic/pneumatic unloading door: located at the bottom of the mixer, it can unload quickly, and some models support manual emergency operation.
Water supply system
Automatic metering water supply: error ≤2%, and the water volume is adjusted by electronic scale.
Electrical control system
It has short circuit protection, overload protection, and phase failure protection functions to ensure safe operation.
Working principle
JS1000 twin-shaft concrete mixer adopts forced mixing mode:
Feeding stage:
Material (cement, sand, gravel, water) is lifted through the hopper or manually put into the mixing drum.
Mixing stage:
The two mixing shafts rotate in opposite directions, driving the blades to forcefully mix the concrete, forming a comprehensive effect of pushing, rubbing, squeezing, etc. to ensure uniform mixing.
Discharging stage:
After mixing, the hydraulic/pneumatic discharge door opens and the concrete is quickly discharged.
Product Advantages
High mixing quality
Twin-shaft forced mixing ensures concrete uniformity, suitable for dry hard, plastic, and lightweight aggregate concrete.
High production efficiency
The theoretical productivity reaches 50-60m³/h, which is more than 30% higher than the efficiency of the self-falling mixer.
Energy-saving and durable
Adopt high-chromium alloy blades and hexagonal mixing shafts, which are highly wear-resistant and have a long service life.
Quadruple seals at the shaft end (wear-resistant rubber + labyrinth seal + floating seal) prevent leakage.
Easy to operate
High degree of automation, it can form a simple mixing station with the PLD batching machine.
Hydraulic unloading + manual emergency device to adapt to different working conditions.
Easy maintenance
The maintenance platform can be lifted to facilitate the inspection of mixing blades and transmission components.
