Multiple paddle options of Double Planetary Mixer

The Double planetary mixer usually contains at least 2 planetary stirring paddles and 1 scraping paddle and often adds 1~2 planetary high-speed dispersion paddles. The stirring paddle can be customized in various forms, the common ones are: twist frame type, multi-layer paddle type, straight frame type, claw type, butterfly type, etc.

The low speed and high torque of the double planetary mixer can not only stir the products with high viscosity but also has the ability to shear and knead the materials. It is one of the most flexible and effective equipment for mixing and dispersing high-viscosity materials and thixotropic materials.

Double Planetary Mixer is mainly used for products whose viscosity is more than one million CPs. It not only has the function of mixing. but also increases the hybrid trajectory for the material mixing movement. the material in a very short time to be fully mixed.

Working principle of double planetary mixer

The two planetary stirring paddles in the tank body rotate around the common axis along the container wall and at the same time rotate around their own axis at high speed, so that the materials in the tank can move up and down and around, and the mixing effect can be achieved in a short time. The automatic wall scraping and bottom scraping device rotates around the inner wall of the container to scrape off the materials adhering to the kettle wall to achieve no dead spots, and efficient and uniform mixing. 

When 1 to 2 high-speed dispersers are added, the high-speed dispersing paddles also perform planetary motions of revolution and rotation, and at the same time combine the strong kneading interference motion of the stirring paddle and the up-and-down/left-right circulation motion, as well as the high-speed shearing and dispersing effect of the dispersing disc. The complex movement of the material is subject to strong shearing, kneading, and dispersion.

Equipment introduction - small and medium-sized double planetary mixer

The small and medium-sized double planetary mixer is a kind of high-efficiency small and medium-sized mixing equipment developed by Chenghai in order to meet the needs of universities, research institutes, and factories for pilot tests. It is also ideal equipment for small-batch industrial production. The stirring part of the equipment is fixed, and the container is lifted; the stirring is safe and stable, and the container is positioned accurately.

The common process of double planetary mixer

Vacuum process: high-viscosity materials generally have low surface tension, and the mixing process is easy to absorb pores and cannot come out naturally. Double planetary mixers are often equipped with a vacuum system, which can be stirred for a long time under vacuum conditions. The material of the air bubbles moves to the surface layer and detaches from the material under negative pressure conditions.

Temperature control process: High-viscosity materials are more sensitive to temperature, often accompanied by heating, cooling, and constant temperature stirring processes, and the equipment is often equipped with temperature detection and control functions.

Dehydration process: some polymer materials are extremely sensitive to moisture content, the lower the moisture content, the better the quality of the material, the vacuum degree can be adjusted in combination with the vacuum process, and the temperature can be adjusted in combination with the temperature control process, which can flexibly meet the needs of dehydration and reduction at various temperatures Limit moisture content requirements.
