Introduction of Double Planetary Vacuum Mixer
Planetary power mixer is a combination of the traditional double planetary mixer and high-speed disperser principle, composed of a new all-round model, currently has a wide range of applications in many fields. For the characteristics of power battery slurry with high solid content and high viscosity, on the basis of the original planetary power mixer, we have developed an enhanced power mixer with higher speed and larger torque. In the design process, the stirrer speed, stirring power, dispersion linear speed, suspension level, liquid flow pattern and the distribution of turbulence intensity in the barrel and other factors are fully considered, and its high-speed dispersion of the highest linear speed of up to 17m/s ± 1, enhanced twist frame can handle any high viscosity battery slurry.

Double planetary vacuum mixer performance characteristics
1. High viscous mixing capacity: Double planetary mixer can deal with high viscosity materials, new mixing method - twist frame clockwise rotation, its rotation counterclockwise, to ensure that there is no dead angle mixing and no “climbing” phenomenon. 2. Vacuum-resistant operation: the double planetary mixer can be operated in a vacuum.
2. Vacuum-resistant operation: The double planetary mixer can be dispersed and stirred in a vacuum-enclosed environment to ensure that the materials are uniformly mixed in a vacuum state, which is suitable for production processes that require a vacuum environment.
3. Diversified heating methods: The kettle of double planetary mixer can be heated by electric heating, steam heating, water circulation heating and other heating methods, and the temperature inside the kettle can be monitored in real time through the temperature control probe to ensure that the material temperature error is less than ±1. In addition, the jacket, the bottom jacket and the coil inside the jacket and the deflector plate can realize the cooling of the material inside the kettle.
4. Automatic control: PLC programming control can automatically monitor and control the temperature and speed of the kettle. Frequency conversion speed control is adopted for both male and female rotation of stirring slurry, so that different rotational speeds can be selected according to different processes and viscosities, and precise control can be realized.
5. High efficiency and high productivity: the mixing paddle of double planetary mixer rotates at the same time, so that the material flows up and down and around the kettle, thus achieving the mixing effect in a very short time, which greatly improves the production efficiency.
6. Fine processing technology: The inner wall of the kettle of double planetary mixer is finished and polished by large vertical lathe, which ensures that the movable scraper on the planetary frame can scrape off the materials on the inner wall of the kettle completely when it is rotating, avoiding the materials from being left behind.
7. Wide range of application: Double planetary mixer is suitable for mixing and dispersing high-viscosity and high-density materials in the fields of chemical industry, new materials, etc., which usually need the matching extruder to extrude the materials from the kettle to complete the whole mixing process.
8. Good sealing performance: Two sets of mechanical seals plus soft and static seals to ensure the vacuum - theoretically sealing performance enhanced by 30%. Temperature sensor directly contact with the material, more accurate measurement, faster response speed, the error is only between ± 0.5 .
Components of double planetary vacuum mixers
Reduction motor: Provide the power source to drive the operation of the mixer.
Planetary box: The mixing shaft in the planetary box rotates around the axis of the barrel while rotating to realize the mixing function.
Stirrer: Usually twisted frame type, there are multi-layer paddle, multi-layer slant paddle, straight frame paddle, butterfly paddle and other options, low-speed rotation at the same time around the center of the kettle center of the rotation of the material mixing at the same time up and down surge.
Disperser: Keep high speed rotation and also rotate around the kettle body, shear and disperse the material, make the agglomerated material dispersed efficiently.
Wall scraper: Rotates closely to the barrel wall to ensure that there is no stagnant material on the barrel wall to improve the mixing effect.
Bucket: Used for holding materials, the inner wall of the bucket is refined and polished to ensure that the wall scraper can completely scrape off the materials on the bucket wall.
Hydraulic lifting system: Used to adjust the position of the mixer to meet different mixing needs.
Frame: Supports the whole structure of the mixer.
Vacuum system: To realize vacuum mixing and eliminate air bubbles in the material.
Temperature control system: Including electric heating, steam heating and oil-water circulation heating to ensure the temperature control of the material during the mixing process.
Safety protection device: To ensure the safety of operation.
Working Principle of Double Planet Vacuum Mixer
Stirrer movement: Double planetary stirrer rotates at the same time as the rotation, which makes the materials do complex movement in the kettle body, and subject to strong shearing and rubbing, so as to achieve the purpose of full dispersion and mixing.
Vacuum state: The vacuum pump inside the tank exhausts the air inside the tank to form a vacuum state, which avoids the interference of air on the mixing process and ensures the homogeneity of mixing.
Temperature control: The temperature in the kettle is monitored in real time by the temperature control probe, and then the temperature control jacket of the kettle body makes the kettle body implement mixing at a specific temperature. The temperature control jacket can be composed of electricity, steam, water, oil, refrigerant, etc., in order to realize cooling or heating.
Difference Between Single-arm and Gantry Type Double Planetary Vacuum Mixer
Structural design
Single-arm double-planet vacuum mixer: This kind of mixer usually has only one mixing arm, and the structure is relatively simple. It usually adopts a single planetary drive mechanism, and the mixing arm rotates at the same time as it rotates, which makes the mixing process more uniform and is suitable for mixing high-viscosity materials.
Gantry type double planetary vacuum mixer: This mixer has two mixing arms, similar to the structure of a gantry, hence the name. It usually has two mixing arms mixing at the same time, increasing the efficiency and uniformity of mixing. The gantry design makes the mixing range wider and is suitable for larger scale mixing needs. The capacity of gantry mixer is more than 300L.
Application Scenarios
Single-arm double planetary vacuum mixer: Due to its simple structure, it is suitable for small batch production or laboratory use. It is suitable for handling materials with high viscosity and high solid content, such as polymer lithium-ion battery liquid, electronic electrode slurry, adhesives, etc.
Gantry type double planetary vacuum mixer: It is suitable for mass production due to its larger mixing range and higher efficiency. It is suitable for applications that require efficient mixing of large quantities of materials, such as large-scale production in the chemical and pharmaceutical industries.
Operation and Maintenance
Single-arm type: Simple operation and easy maintenance, suitable for small-scale equipment and laboratory use.
Gantry type: Higher operating complexity and higher maintenance cost, but suitable for large-scale production and able to meet higher production demands.
