JN1500A Planetary Concrete Mixer
JN1500A is a vertical axis planetary concrete mixer, which adopts a unique planetary motion mixing principle and is suitable for mixing dry hard concrete, plastic concrete and various special mortars. This model is widely used in large-scale infrastructure projects such as commercial concrete mixing stations, precast component plants, high-speed railways, bridges, and water conservancy projects, especially suitable for PC component (precast concrete) production lines and underground pipe gallery construction.
Feed Capacity：2250L
Discharge Capacity : 1500L
Motor Power: 3x22Kw
Voltage: 220v/380v/415v/440v/480v(50Hz/60Hz)
Product Structure
Mixing system
Planetary mixing mechanism:
Revolution + rotation: The mixing arm revolves around the central axis and rotates at high speed to achieve mixing without dead angles.
Mixing blades: Made of high chromium alloy, with strong wear resistance and replaceable design.
Side scraper arm: Prevent concrete from adhering to the drum wall and ensure mixing uniformity.
Transmission system
Planetary reducer: Adopts special reducer with high transmission efficiency and long life.
Motor drive: 3 22kW motors are driven in parallel to ensure high torque output.
Discharging mechanism
Hydraulic/pneumatic control:
Adopt fan-shaped discharging door, equipped with 3 proximity switches to accurately control the switch state.
Emergency manual pump: The discharging door can be opened manually when the power is off to prevent the concrete from solidifying.
Water supply system
Annular water spray device: Uniform water supply, error ≤2%, and can clean the mixing arm at the same time.
Working principle
Feeding stage:
Aggregates, cement, water, etc. are transported into the mixing drum through a lifting hopper or belt conveyor.
Mixing stage:
Planetary motion: the mixing arm revolves and rotates to form a three-dimensional compound motion, which allows the material to be fully sheared, squeezed, and tumbled.
Discharging stage:
The hydraulically driven fan-shaped door opens quickly (≤5 seconds), and the concrete is discharged evenly.
Product Advantages
High mixing quality: planetary motion + side scraper arm, homogeneity ≥ 95%, no segregation.
High production efficiency: 30% faster than traditional mixers.
Strong wear resistance: high chromium alloy blade liner, life ≥ 100,000 mixing times.
Convenient maintenance: modular design, blades can be replaced quickly, downtime ≤ 30 minutes.
Strong adaptability: can mix lightweight aggregate and fiber concrete, suitable for PC component production.
