Ball milling is a grinding method that grinds nanotubes into extremely fine powders. during the ball milling process, the collision between the tiny rigid balls in a
A ball mill circuit has two efficiencies because it has two main functions the grinding of coarse particles and, the removal of the fine particles to make room for grind- ing more coarse particles in the ball mill.
In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. then, discharge of ground material performed through the central hole in the discharge cap or through the
A ball mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. the rotation is usually between the larger the diameter, the slower the rotation.

Pressure and temperature measuring system in order to understand the processes which occur during grinding with ball mills e.g. chemical reactions, phase changes, it is helpful to record the most important thermodynamic parameters pressure and temperature. planetary ball mills are frequently used for the development of new materials by mechanical alloying due to their high energy input.
Planetary ball mills are used wherever the highest degree of fineness is required. in addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying. the extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and
