mills which, due to their geometry, cause the different impulse transitions: Rods – linear impact energy Balls – punctual impact energy Cylpebs – linear and laminar impact and friction energy. Consequently, for achieving an optimal energy transmission, the correct choice of grinding media is essential.

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.

The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry.
