What is planetary centrifugal mixer

Planetary centrifugal mixer is a kind of mixing equipment for mixing raw materials. It can mix a variety of materials, including high-viscosity materials, liquid materials, and even nano-scale powder materials. The principle is to rely on the revolution and rotation of the container holder to stir and degas the materials. The mixing and degassing are performed with super strength and high speed, and the mixing is uniform without bubbles or stratification. It can be used with a high-power vacuum pump to perform stirring and vacuuming at the same time to remove nano-scale bubbles in the material.


There are a variety of capacity specifications to choose from, which can mix materials of different weights and meet all requirements from testing to mass production. The bladeless design will not destroy the shape and function of the material when stirring and dispersing the material. It can stir and defoam a small amount of material and reduce the loss during the mixing process. Parameters such as time and rotation speed can be set. The stirring parameters vary with different products. The equipment has a storage function and can set the stirring parameters for different materials. It is widely used in the field of material mixing in various industries. It has a high technical level in material mixing, is simple to operate, efficient and excellent, and some can be customized according to customer requirements.

Working principle of planetary centrifugal mixer 
Working principle of planetary centrifugal mixer:
Centrifugal planetary mixerdo not require mixing blades and can mix and degas materials at the same time.
To achieve this goal, three key factors need to be considered.
This uses centrifugal force to move material away from the center.
 Rotation and shearing are achieved by rotating the container and causing the material to flow.
 45 degree rotation. By tilting the axis of rotation to a 45-degree angle, three-dimensional flow is created.
In addition, the flow rate (direction) between the liquid surface and the container wall changes rapidly, causing complex flow and strong shear forces. In particular, strong shear forces make droplets and particles smaller, enhancing their dispersion. Air bubbles are also finely dispersed and eliminated during this process.
Centrifugal Mixer - Smida Mixer
How to mix low viscosity materials
By changing the balance between revolution speed and rotation speed, degassing can be achieved based on the following two principles. The container support is tilted 45° relative to the revolution axis. After the equipment is started, the motor transmits power to the container support through the transmission structure. The clockwise revolution relative to the revolution axis generates centrifugal force, and the counterclockwise rotation relative to the container's rotation axis generates shear force. Through high-speed rotation, the material produces convection, impact and shear. The interaction of the two forces produces vortex and up-and-down convection, pushing bubbles out of the material, and no bubbles are mixed during mixing and dispersion.

How to mix high viscosity materials
Even in a short time, high-viscosity materials can be mixed evenly without using mixing blades.
Defoaming is based on the following three principles:
When viscosity is high, bubbles rise slowly and convection currents through the material bring the bubbles to the surface.
The reduction in pressure causes the bubbles to expand and be destroyed. Solvent bubbles are also produced.
Due to the rotation, small bubbles on the liquid surface are also sheared and destroyed.
Centrifugal Planetary Mixer - Smida Mixer
Diffevent between the Vacuum planetary centrifugal mixer and Non-Vacuum planetary centrifugal mixer
Planetary centrifugal mixers are divided into two types: non-vacuum planetary centrifugal mixer type and vacuum planetary centrifugal mixe type. Air bubbles often cause problems during mixing, in which case one of these two types can be used depending on the purpose and use.
Non-vacuum planetary centrifugal mixer removes visible air bubbles.
Vacuum planetary centrifugal mixe can be used when invisible micron bubbles need to be removed.
In the past, degassing with a dryer etc. took a long time after stirring in a mixer. The planetary centrifugal mixer can achieve degassing while stirring without worrying about overflow, which greatly shortens the time.
What is Vacuum Mixer
The vacuum planetary centrifugal mixer is equipped with a powerful vacuum pump. It is an efficient mixing equipment that integrates stirring, degassing and vacuuming functions. It has a built-in vacuum system. , the mixing is completed in a vacuum environment, which can effectively eliminate bubbles generated during the mixing process, degas the material cleanly and efficiently, greatly improving the filling of the material and the compactness of the model, and is suitable for various high-quality materials such as paste, slurry, glue, etc. Viscosity material, good effect and fast speed.

What is Non-Vacuum Mixer
Most non-vacuum planetary centrifugal mixers are equipped with a "defoaming mode". Degassing is performed by changing the balance between revolution speed and rotation speed. The centrifugal force generated by the revolution of the non-vacuum planetary centrifugal mixer "pushes small bubbles to the liquid surface. By applying slow rotation that does not engulf the bubbles, the bubbles that have risen to the liquid surface are destroyed through shear force." It is suitable for mixing various low- to high-viscosity materials such as liquids and powders, with good effect and fast speed.
The vacuum centrifugal planetary mixer has its own vacuum system, which can remove nano-scale bubbles in the material to make the mixing effect more uniform.
The vacuum centrifugal planetary mixer has its own vacuum system, which can remove nano-scale bubbles in the material to make the mixing effect more uniform. It is suitable for materials with vacuum decompression function that require high mixing accuracy and high air content in the material.
The non-vacuum mixer replaces manual mixing through planetary motion. The mixing efficiency is greatly improved, and the uniformity of mixing is also more uniform than manual mixing. It is suitable for materials containing volatile components that are not suitable for vacuum degassing.

Technical Principles

The planetary centrifugal mixer breaks the traditional mechanical mode and cleverly integrates non-contact means such as planetary motion and centrifugal force synergy to achieve material mixing.

Small TextThe stirring principle of rotation and revolution:
The container bracket is tilted at a 45 degree angle relative to the axis of revolution, and the container containing the material is fixed on the bracket.
Revolution: Clockwise orbital rotation (to complete defoaming)
Rotation: counterclockwise rotation, rotating around the center of the container as the axis on the orbital path (to complete mixing)
The interaction between rotation and revolution generates vortices and upward and downward convection, pushing out bubbles from the material without mixing them during stirring and dispersion.
Core Parameter Analysis

Non contact stirring: avoids contamination or damage to materials caused by traditional mechanical stirring, and improves the reliability of experimental results.
Optional temperature control and networking components, supporting temperature adjustment during the mixing process, ensuring that heat sensitive materials are processed in a stable environment; Support online calling and data export, facilitating product batch traceability.
Design Advantages
Efficient mixing
The mixer, relying on planetary mixing and centrifugal force, can quickly and evenly mix materials. Traditional mixers may require multiple agitation and extended time to achieve uniformity when processing complex materials, while planetary centrifugal mixers can significantly shorten mixing time and improve production efficiency., Traditional mixers take several hours, while this equipment can complete high-quality mixing in just a few tens of minutes.
Broad applications
The design without stirring blades makes it highly adaptable to material characteristics, making it easy to handle low viscosity liquids, high viscosity pastes, and solid-liquid mixtures containing particles. Due to the lack of direct contact between the stirring blade and the material, there will be no damage to the stirring blade or blockage of the material due to differences in material characteristics, such as mixing materials with high viscosity and easy adhesion.
Clean and environmentally friendly
The design without stirring blades eliminates the hygiene dead corners caused by the contact between stirring blades and materials, facilitates equipment cleaning, reduces the risk of material residue, and meets the strict hygiene requirements of industries such as food and medicine. Meanwhile, the non-contact mixing method reduces noise and energy consumption, making it more environmentally friendly.
