In today's industrial production, grinding and dispersion technology, as a key process to improve the physical and chemical properties of materials, is constantly promoting technological progress in various fields. Especially in the field of battery materials, ink coatings, medicine and other new materials.
This paper will deeply discuss the status quo and principle of grinding and dispersion technology, and focus on the advantages of Boyee nano Bead mill in nanometer powder grinding and dispersion.
Current situation and development of grinding and dispersion technology
Grinding technology is a process in which materials are broken into smaller particles to improve their physical and chemical properties. At present, grinding technology has developed quite mature, a variety of new grinding equipment and methods continue to emerge.
For example, nano-grinding technology can improve the physical and chemical properties of materials by breaking them down to the nanoscale.

Dispersion technology focuses on the uniform dispersion of non-uniform materials in liquids or gases to form a stable dispersion system. In practical applications, grinding and dispersion often complement each other and jointly promote the crushing and uniform dispersion of materials.
Principles of grinding and dispersion
In the grinding process, the collision and friction between solid particles are very important. This effect is generated by the high-speed rotation of the rotor structure, such as a turbine or rod pin, which displaces and deforms the particles' surface molecules, thereby reducing the particle size.
At the same time, grinding can also promote the dispersion and mixing of particles and improve the reaction rate. Fracture and dissolution during grinding also help to speed up the reaction process.
Nanometer powder grinding and dispersion technology
In the grinding and dispersion of nano-scale powder, the Bead mill plays a central role. The grinding disc and grinding bead work in a high-speed rotation mode, and the centrifugal force and shear force generated effectively promote the collision and friction between the powder and the zirconium ball, and achieve the dispersion and refinement of the particles.
Choosing the right dispersion medium, such as water, zirconium balls, organic solvents and auxiliaries, can help disperse the powder particles to a smaller size, which is not easy to agglomerate.
The zirconium ball is the key dispersion medium in the sanding mill, and the choice of its material, size and density directly affects the dispersion effect. Reasonable zirconium ball configuration can provide the appropriate impact and shear forces to achieve efficient dispersion and refinement. At the same time, controlling the grinding time is also a key factor to ensure the dispersion effect.
Design advantages of Boyee nano bead mill
The internal structure design of Boyee nano bead mill, the rotor adopts the structure of turbine and rod pin, drawing on the principle of gear meshing, and realizes the rapid grinding and dispersion of materials through high-speed rotation.
The turbine structure is exquisitely designed and the shape and Angle of the blades are optimized to ensure a strong impact and grinding effect on the material when rotating at high speeds. The rod and pin structure grinds the material into finer particles through friction and shear caused by high-speed rotation.
The rod pin structure of Boyee nano bead mill has a high linear speed and a certain extrusion pressure inside, which makes the kinetic energy transferred to the grinding zirconium ball greater, and the impact and grinding effect on the material more intense. This design helps the particle size to develop in the nanometer direction and achieve a finer grinding effect.
In terms of dispersion technology, the internal structural design of Boyee nanomander also fully considers hydrodynamic factors, such as flow rate, velocity, pressure, etc., to optimize the grinding and dispersion process.
In the power battery conference held in Shanghai from November 18 to 20, Boyee successfully won the trust of many battery material manufacturers by virtue of its own technology iteration and upgrade, and became the annual product trust enterprise.
