This unique way of movement allows materials to undergo complex and thorough movements inside the barrel, achieving the ideal effect of uniform mixing.
2、 The exquisite structure of the dual planetary mixer
Its structure consists of multiple key components:
1. Blender: Directly acts on the material to achieve mixing and stirring.
2. Motor: Provides a powerful and stable power source.
3. Sealing system: effectively prevents material contamination and ensures the purity of production.
4. Deceleration system: Ensure smooth operation of the equipment and provide stable working power.
5. Base: Provides stable support for the entire device.

The laboratory dual planetary mixer has significant characteristics:
When the planetary carrier rotates, it drives the three mixing and dispersing shafts inside the box to revolve around the axis of the material bucket while rotating at high speed, causing strong shear and kneading effects on the material, achieving the goal of full dispersion and mixing.
2. The scraping wall on the planetary carrier rotates with the planetary carrier and continuously scrapes against the barrel wall to avoid material retention and significantly improve the mixing effect.
3. It can work under vacuum and continuously discharge water and other volatile substances, thus serving as a degassing kettle.
In short, the dual planetary mixer plays an important role in lithium battery equipment and many industries with its unique working principle, exquisite structure, and wide application, providing strong guarantees for the production of high-quality products.

Sand mill is a horizontal wet continuous production grinding disperser. The pre stirred raw materials are sent to the grinding tank of the host machine. The grinding tank is filled with an appropriate amount of grinding medium. Through the high-speed rotation of the dispersion blade, the grinding medium is given enough kinetic energy to collide with the dispersed material particles to produce shear crushing force and extrusion crushing force, so as to achieve the effect of dispersion. Then, the dispersed materials are separated from the grinding medium through a special separation device.


Development of sand mill


According to the development of sand mill, it can be divided into five stages: vertical mixing mill, vertical disc sand mill, vertical pin rod sand mill, horizontal disc sand mill and horizontal pin rod circulating sand mill.


Grinding technology of sand mill


There are four main grinding processes of sand mill: continuous grinding process, series grinding process, combined cycle grinding process and single barrel cycle grinding process. The premise of single barrel circulating grinding process is that the number of cycles is greater than 5, and the circulating barrel is equipped with an agitator to ensure full mixing of materials and avoid dead corners in the circulating barrel. The process has simple operation and small equipment investment. It is generally used for grinding ceramic raw materials, such as silicon carbide, silicon nitride, boron carbide, etc.
