JN2500 Planetary Concrete Mixer
JN2500 planetary concrete mixer is a medium-sized mixing equipment with compact design, suitable for use in small and medium-sized engineering sites. It uses planetary mixing technology, which can complete high-uniform concrete mixing in a short time. It is mainly used for mixing ordinary concrete, ready-mixed concrete and various special concretes (such as self-compacting concrete, high-strength concrete, etc.).
Feed Capacity：3750L
Discharge Capacity : 2500L
Motor Power: 3x37Kw
Voltage: 220v/380v/415v/440v/480v(50Hz/60Hz)
Product Structure
The structure of JN2500 planetary concrete mixer mainly consists of the following parts:
Mixing tank
The mixing tank is made of high-strength wear-resistant steel and is designed as a double-axis or multi-axis structure.
A special lining protection device is installed inside to extend the life of the equipment.
The tank capacity is usually 2500 liters (depending on the specific model), which is suitable for medium-sized mixing needs.
Mixing device
The mixer consists of multiple planetary blades, usually with a double-axis or three-axis design.
While the blades rotate around the central axis, they also revolve and rotate themselves, forming a complex planetary motion trajectory to ensure uniform mixing of concrete.
Drive system
Equipped with high-power motors and reducers to provide stable power output.
The transmission system usually adopts gear or belt drive to ensure efficient operation of the equipment.
Feeding and discharging system
The feeding port is reasonably designed to facilitate material delivery; the discharging port adopts a tipping bucket or sliding door design to facilitate quick unloading.
Some models are equipped with automatic batching devices to improve mixing efficiency and accuracy.
Control system (electric control box)
Equipped with an intelligent control panel, supporting manual operation and semi-automatic control.
Parameters such as mixing time and speed can be preset to achieve precise control.
The electric control system has safety protection functions such as overload protection and emergency shutdown.
Support and walking device
The equipment usually adopts a mobile design and is equipped with rollers or anchor bolts.
It simplifies the installation and transportation process of the equipment and is suitable for use on construction sites with high mobility.
Working principle
The working principle of JN2500 planetary concrete mixer is based on its unique planetary mixing technology:
Feeding stage
Concrete raw materials (cement, sand, gravel, water, etc.) enter the mixing tank through manual or automatic batching system.
Mixing stage
The mixer is driven by an electric motor, and the blades rotate around the central axis while revolving and rotating.
This planetary motion trajectory makes the material form a complex flow state in the mixing tank, ensuring that all components are fully mixed.
Usually, the mixing time is controlled at 30-60 seconds, depending on the concrete formula and performance requirements.
Discharging stage
After the mixing is completed, the mixing tank is turned over or the discharge door is opened, and the concrete is discharged through the discharge port.
Some models support continuous mixing or automatic discharging to improve work efficiency.
