The double planetary mixer is a high-efficiency mixing equipment with no dead center, integrating dispersion and mixing. It has the characteristics of strong adaptability, a wide range of uses, and stable performance in the production of materials. The double planetary mixer is a high-end mixing equipment, but it is particularly suitable for dissolving, mixing, kneading, and reaction processes from powder to high-viscosity and high-density materials.

Details of Double Planetary Mixer

  • The common agitators include paddle type, twist type, claw type, and frame type.
  • good mixing, reaction, kneading, and dissolution functions.


inks, colorants, dyes, coatings, and other industries.

The double planetary mixer is mainly composed of a main machine, a sealing cover, a mixing barrel, a mixing paddle, and a dispersing component. Among them, the dispersion disc stirring paddle of the mixer has achieved planetary motion that can satisfy both revolution and rotation. The speed of the double planetary mixer can be adjusted through the frequency converter so that the materials can undergo complex movements and be strongly dispersed and squeezed to ensure that the materials are fully dispersed and mixed. The double planetary mixer is mainly used for stirring, mixing, and dispersing powder and liquid materials to obtain a uniform slurry. Different mixing paddles can be selected according to different production processes and material characteristics.

Working principle of double planetary mixer

1. During the working process of the double planetary vacuum mixer, the two parallel stirring paddles operate according to the set fixed rotation ratio. While revolving along the mixing barrel, the double planetary mixer rotates rapidly, and the swirling scraper in the mixing barrel also performs rapid revolution simultaneously, so that the material passes through the inner wall of the mixing tank and quickly moves to the position of the stirring paddle. The direction of rotation of the agitator and the direction of revolution can be in the same direction or reversed, and finally achieve different shearing effects.

2. The high-speed dispersing toothed discs of the other two separate power units will also rotate with the mixing barrel to carry out efficient dispersion and emulsification processes. The high-speed dispersing tooth disc adopts frequency conversion speed regulation, and the user can choose the best speed for the material according to the production process.

3. The double planetary mixer has high-speed dispersion and low-speed mixing motion modes, which can achieve a completely uniform emulsification mixing effect of materials in a short time. It is especially suitable for the dispersion and mixing of solid-solid phase, solid-liquid phase, and liquid-liquid phase.

Advantages of double planetary mixer

1. The barrel wall of the double planetary mixer will be mirror-polished and easy to clean. Both the barrel wall and the barrel bottom are of a double-layer jacket structure, which may greatly increase the cooling and heating area, and increase the heating and cooling speed. The equipment comes with a circulating heating system and a cooling temperature control device. FRANLI can make jacketed heating and cooling according to customer requirements.
2. The soft seal plus three mechanical seals can make the sealing of the equipment perfect so that the double planetary mixer has a very high vacuum tightness.
3. The mixing method developed by FRANLI: (twist frame) The stirring paddle rotates clockwise, and its rotation is counterclockwise. This not only retains the “eating and shearing” performance of the twisted frame but also reduces the mixing of materials during the mixing process. “Climbing” phenomenon.
4. The agitator of the double planetary mixer adopts variable frequency step-less speed regulation. The manufacturer can replace the agitator with different shapes (straight frame type/spiral type/blade type) according to the customer’s production process to make the mixer more scientific and precise. (Stirring) The distance between the paddle and the paddle and the barrel wall is designed. The stirring paddle is cast from stainless steel with precision grinding tools. The distance between the mixer itself is 2~3mm, and the distance between the stirrer and the inner wall of the mixing tank is 2~4mm (100L following specifications);
5. The precision speed measuring device can accurately measure the timely speed of the mixer, and the speed display error is +0.5~2r/min;
6. The precision temperature measuring device (PT100) is located in the middle of the mixing barrel. The temperature measuring rod moves synchronously with the mixer in the barrel, which can accurately measure the temperature of the material.

Structural features of double planetary mixer

1. The soft seal between the mechanical seal and the kettle body allows the material to be operated under vacuum;
The kettle body can be heated by electric heating, steam heating, and oil-water circulation heating. The temperature detection device on the kettle body ensures that there is no temperature error, and the coil inside the jacket can achieve cooling;
2. The inner wall of the kettle is precision machined by a large vertical lathe to ensure that the movable scraper on the planet carrier completely scrapes off the material on the inner wall of the kettle when rotating;
3. The kettle body is equipped with a double-frame mixing paddle or a multi-blade mixing paddle that scrapes the bottom. It also rotates while revolving, making the material move up, down, and around, so that the mixing effect can be achieved in a short time;
4. The revolution and rotation of the stirring paddle in the kettle are adjusted by frequency conversion, and different speeds can be selected according to different processes and different viscosities;

Advantages of double planetary mixer

1. The structure and operation are convenient, and the operation is safe and reliable. There will be no abnormal problems such as the mixer cannot be stirred, the mixing effect is poor during the mixing process, the mixer is frequently overheated and overloaded, and the slurry is stuck during the mixing process.
2. The mixing speed is fast and the quality is uniform. The double helix of the power mixer is arranged asymmetrically, one large and one small expand the mixing range, so it is more suitable for mixing materials with a large difference in specific gravity.
3. The energy-saving effect is remarkable. Compared with the drum mixer, this machine consumes only ten times the energy.
4. The wear and pressure of granular materials are minimal, and no overheating reaction occurs when mixing heat-sensitive materials.
