Planetary ball mills 101 planetary ball mills share the same design as other basic ball mills a grinding jar filled with media and rotated on its own axis but their unique design takes advantage of centrifugal force and the coriolis effect to grind materials to a very fine or even micron size.
We are a mining equipment company integrating scientific research, production and sales, committed to the production of mining equipment and the development of environmental protection.

Planetary ball mill pm 100 general information planetary ball mills are used wherever the highest degree of fineness is required apart from the classical mixing and size reduction processes the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes.
The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size the large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls ball mills grind material by impact and attrition.
Impact and attrition sizereduction methods include air classifying mills pin mills hammer mills and jet mills shear impact and compression methods are used in media or ball mills the five types of milling technologies discussed in this article cover more than 90 percent of sizereduction applications in major chemical food.

Mills with size reduction media ball mills dry ball mills are basically made of a drum partially filled with a grinding media typically beads of ceramics or steel the mill is filled with the grinding beads as well as the product then the mill is rotated until a speed.
The time required to obtain a specific particle size is often less than in a planetary ball mill even in processes where no interruption in the grinding times are required in planetary ball mills thanks to the more efficient grinding mechanism.
