Agitated Ball Mills SolidsWiki

High rotation speed and low media filling level effect a tendency to impact stress, whereas a high filling ratio of beads shifts the mechanism more to shear stress. In contrast to agitated wet ball mills, dry ball mills are typically low speed mills with predominant shear grinding.

How Mass, Velocity, and Radius Affect Centripetal Force

You can see the effect of the radius in your car going around in a circle. If you drive your car at a fixed speed in a circle of smaller and smaller radius, eventually your tires won't be able to supply enough centripetal force from the friction, and you'll skid off the circular path.
