High Quality Vertical Planetary Grinding Ball Mill for Lithium Battery Lab Research
AOT
Xiamen, China
20-45 working days
50 Sets/Month
Planetary Ball Mill has four ball grinding tanks installed on one turntable. When the turntable rotates, the tank axis makes planetary movements. The balls and samples inside the jars are impacted strongly in high-speed movement, and samples are eventually ground into powder. And these Alumina Ceramic Jars are used whenever small quantity of samples need to be grinded.
Vertical Planetary Grinding Ball Mill for Lithium Battery Lab Research
Description:
Oil seal mute planetary ball mill has small volume, comprehensive function, high efficiency, and low noise which is the ideal device for obtaining micro-particle research samples used for research and development institutes, colleges and universities, and entire laboratories. The samples could be ground under vacuum state using the vacuum ball mill jars. According to the processing requirement set the rotation speed and alternate time of forward and reversal rotation and set the total grinding time.
In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen.

A. A ceramic planetary ball mill is a type of grinding mill that utilizes ceramic jars and ceramic balls for milling and grinding applications. It operates on the principles of impact and attrition, where the grinding balls in the jars are subjected to high-energy collisions with the sample material, resulting in the reduction of particle size.
B. The planetary ball mill design includes multiple grinding stations arranged on a planetary disk. Each grinding station consists of a jar filled with the sample material and grinding balls. As the planetary disk rotates, the jars revolve around their axes, simultaneously rotating in the opposite direction around the center of the disk. This dual rotation motion creates a strong centrifugal force, causing the grinding balls to impact and grind the material within the jars.
C. Ceramic planetary ball mills are known for their high grinding efficiency, uniform particle size distribution, and precise control over the grinding process parameters such as speed, time, and rotational direction. They are widely used in various fields, including materials science, chemistry, ceramics, electronics, and pharmaceuticals, for research and development, quality control, and production-scale grinding applications.
2.The role of battery planetary ball mill
Battery planetary ball mill plays a crucial role in the field of battery material preparation, it through its unique planetary motion mechanism, that is, the mill tank rotates while rotating, to achieve high strength, high efficiency mixing and fine grinding between materials. This process not only promotes the uniform dispersion and nanoscale refinement of key components such as positive and negative electrode materials, electrolytes and additives, but also significantly improves the specific surface area and activity of the material, thereby enhancing the energy density, cycle stability and rate performance of the battery. In short, the battery planetary ball mill is an indispensable advanced equipment to optimize the structure of battery materials and improve battery performance.
3.planetary ball mill
In the preparation of battery materials, the battery planetary ball mill plays a crucial role. The operator first needs to precisely set the speed, time and ball ratio of the ball mill to ensure that the material is evenly mixed and the particle size distribution is in line with the requirements. Then, the pre-weighed positive and negative active material, conductive agent and binder and other raw materials are carefully put into the ball mill tank to start the machine. Under the double action of high-speed rotation and complex trajectory movement, the raw material particles undergo impact, shear and grinding, and finally achieve efficient refinement and uniform mixing. The entire process needs to be closely monitored to ensure safe operation and product quality, laying a solid foundation for subsequent battery manufacturing.
