The core challenge to grinding a perfect ball is maintaining a precise radius from the tip of the nose back to the shank of the tool. To achieve this, a relief must be ground into the end of the tool, that leads out to an intersection of the outside diameter so that when it gets to the tangent point, creates a perfect radius.
The difference in speeds between balls and jars produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill, both, in ball to ball and ball to wall interactions. Planetary mills with ...
This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.
