Planetary Concrete Mixer
360° Dead-Angle-Free Mixing
Shortened Mixing Time
High-Quality Concrete Production
Easy Maintenance
————
The complex motion trajectory ensures all-around, high-intensity mixing of the materials.
Planetary Concrete Mixer (also known as Vertical Shaft Mixer) adopts a mixing method that combines revolution and rotation. While the mixing arms rotate on their own axis, they also revolve around the central axis of the mixing drum, ensuring that the mixing trajectory covers every part of the drum. This enables a comprehensive, dead-zone-free, 360-degree high-homogeneity mixing of materials. This unique mixing pattern effectively eliminates motion dead zones, ensures uniform blending, and shortens the mixing cycle by approximately 20% to 40%, significantly boosting production efficiency. Planetary mixers are not only suitable for concrete production—especially high-strength concrete—but are also widely used in fields such as refractory materials, glass, and ceramics, where exceptional mixing uniformity is required.
AGICO’s planetary concrete mixers feature a compact structure, smooth transmission, small footprint, and a leak-free design. Our equipment can be configured for either fully automatic or semi-automatic operation modes. From selecting the optimal model to customizing for special applications, we offer comprehensive technical support and maintenance services. If required, we can also provide a complete concrete batching plant solution tailored to your application.

AGICO Planetary Concrete Mixer Details
Mixing Device
The mixing system adopts a countercurrent planetary bi-directional mixing method with a complex mixing trajectory, delivering highly efficient and uniform blending. The blades feature a bi-directional double-curved design, making the mixing process faster and more energy-efficient.
The streamlined mixing arms are fitted with wear-resistant sleeves to minimize material adhesion on the shafts, greatly extending service life. Reinforced scrapers with reversible blades eliminate dead zones and double the blade’s usable lifespan.
The arms are made from high-quality forged alloy steel, offering excellent toughness and fatigue resistance. Liners use 8mm+8mm wear-resistant overlay composite plates. Blades are available in high-nickel alloy or polyurethane; liners can be cast iron, imported wear plate, or high-wear overlay materials—ensuring adaptability for different material mixing requirements. The overall structure ensures even fiber distribution and prevents clumping.
Main Frame
The main frame is manufactured using a jig welding process for high rigidity and resistance to deformation.
Equipped with a vertical hydraulic station and a standard hydraulic double-door system, it enables alternating production to improve efficiency. The mixing process uses a continuous vortex motion with strong shearing force for excellent uniformity.
Transmission System
The drive system uses a hardened gear reducer. The motor and reducer are connected via an elastic coupling or hydraulic coupler to effectively absorb operational shocks.
The reducer drives the mixing arms for both rotation and revolution, while the scraper arms revolve—creating a complex, powerful mixing trajectory for high efficiency and consistent quality.
The system operates stably under harsh working conditions, efficiently distributing power with high stability, low maintenance requirements, and excellent reliability. It offers high transmission efficiency, large torque, and low noise.
Discharging System
The discharge system can be pneumatic or hydraulic, with customizable door positions and up to three discharge doors. Each door is equipped with special seals to ensure reliable sealing.
The hydraulic pump station includes a manual discharge function for emergency door opening during power outages. Adjustable limit switches allow control of door opening size for precise discharge speed management.
Large inspection doors make cleaning and maintenance easier, with a key-operated safety control system that prevents motor operation during maintenance.
Nozzles
The nozzles use a spiral solid cone design to produce fine, even atomization over a wide coverage area.
This ensures the material is thoroughly moistened during mixing, enhancing uniformity and overall quality.
Working Principle of a Planetary Concrete Mixer
A planetary concrete mixer relies on a planetary shaft with blades installed inside the mixing drum. Through squeezing and overturning actions, it forces the materials to mix, achieving high uniformity and homogeneity. The carefully engineered combination of rotation (self-rotation) and revolution (planetary motion) ensures smooth, continuous material movement inside the drum. This design maintains uniform blending and prevents segregation, even when handling aggregates of different particle sizes and densities—guaranteeing stable concrete quality.
During operation, the material in front of the mixing arm is pushed forward and influenced by centrifugal force, moving in a circular motion on the horizontal plane while also undergoing convection. The relative motion generates compressive and shear forces that push the material upward. The material behind the mixing arm then fills the void left in front, moving downward under gravity. This creates simultaneous horizontal and vertical flows within the mixture. This process not only breaks apart cement particle agglomerations but also promotes thorough bonding between cement molecules and water molecules, achieving uniform distribution at a microscopic level.
The mixing trajectory forms an efficient, highly uniform, and dead-zone-free curve pattern, with materials gradually layered and densely blended. The entire process operates in an accelerating state, delivering fast, low-energy mixing, ultimately achieving high uniformity and high efficiency.
Mixing Trajectory Coverage
With every four revolutions (about 6 seconds), the planetary motion completely covers the mixer’s bottom plate, leaving no dead zones.
