JS500 Twin Shaft Concrete Mixer
JS500 is a twin-shaft 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 small and medium-sized projects.
Capacity：≥25m³/h
Warranty: 18 months
Mixer Motor Power: 18.5Kw
Voltage: 220v/380v/415v/440v/480v(50Hz/60Hz)
Product Structure
JS500 mixer is mainly composed of the following core components:
Mixing system
Mixing drum: adopts double horizontal shaft design, with spiral blades inside to ensure uniform mixing of concrete.
Mixing arm and blades: cast by special process, strong wear resistance, good mixing homogeneity.
Transmission system
Reducer: independently designed and developed, strong overload resistance, stable transmission.
Motor drive: adopts dual motors (mixing motor + winch motor) to ensure efficient operation.
Feeding system
Winch mechanism: adopts double limit design to ensure safe operation of hopper.
Hopper: can be lifted above the mixing drum to realize automatic feeding.
Water supply system
Automatic metering water supply: error ≤2%, to ensure accurate concrete ratio.
Unloading system
Bottom-opening door unloading: hydraulic/pneumatic control is adopted, and unloading is fast and clean.
Electrical control system
Short circuit protection, overload protection, and phase failure protection ensure safe operation.
Working principle
JS500 adopts forced mixing mode, and the specific process is as follows:
Feeding stage:
Material (cement, sand, gravel, water) is lifted by the hopper or manually put into the mixing drum.
Mixing stage:
The two mixing shafts rotate in opposite directions, driving the blades to force the concrete to mix evenly.
Discharging stage:
After mixing, the bottom door mechanism opens and the concrete is quickly discharged.
Product Advantages
High mixing quality
Forced mixing ensures the uniformity of concrete and is suitable for dry hard, plastic and lightweight aggregate concrete.
High production efficiency
The theoretical productivity is 25m³/h, which is more than 30% higher than the efficiency of the self-falling mixer.
Easy to operate
It has a high degree of automation and can be operated alone or combined with a batching machine to form a simple mixing station.
Easy maintenance
The shaft end sealing technology (quadruple sealing) extends the service life of the equipment.
Modular design makes it easy to repair and replace parts.
Strong adaptability
It is suitable for a variety of scenarios such as construction sites, roads and bridges, and water conservancy projects.
