JN Series
Planetary Concrete Mixer, Single-Drive
Vertical shaft mixer for concrete batching plants
- Discharge Capacity 0.5 – 1.0 m³ / batch
- Drive Efficiency Efficient single-motor design for easy maintenance
The small vertical shaft planetary concrete mixer adopts a hydraulic discharge system, ensuring smooth opening and closing of the discharge gate with high thrust and low risk of material jamming. The number of discharge gates can be configured as one or two according to customer requirements. The mixing system combines revolution and rotation in a planetary mixing pattern, achieving more uniform material mixing while eliminating shaft-end slurry leakage issues in the transmission system.
With a compact structure and excellent performance, this mixer is well suited for precast industries such as block production, pipe piles, and PC components.

Main Components
Gear Reducer
The small vertical shaft planetary concrete mixer adopts a single-motor drive configuration, combined with a high-performance reducer and motor. This design ensures smooth operation, low noise, high output torque, and long service life.
Mixing System
Wear parts of the mixing system are made of wear-resistant high-chromium alloy cast iron, significantly extending service life.
Discharge Gates
A patented adjustable discharge gate design provides excellent sealing performance while reducing seal wear. The hydraulic discharge system allows smooth operation, with up to three discharge gates available according to requirements.
Safety Switches
A contact limit switch is installed on the top cover inspection door. When the door is opened, the main motor stops automatically to protect maintenance personnel. A key-operated safety switch is also provided on the mixer body for emergency stop and maintenance. Removing the key prevents accidental operation.
Water Supply System
The water supply system uses multi-angle spray nozzles to ensure uniform water distribution, enabling faster and more uniform mixing.
