Vibratory mills consist of cylindrical or troughlike elastically suspended grinding pipes, which by means of a balanced mass system, are excited to circular vibrations with accelerations Rω 2 (R the radius of the vibratory circle of motion and ω the angular velocity of the unbalanced mass) of up to approximately 10 g — rarely above that. Inside the grinding pipes are grinding media (balls ...
