Abstract
The present invention provides method and apparatus to continuously operate a bead mill. At the outlet of the bead mill is a separator screen which prevents particles of a certain size from being discharged. After running the bead mill, the screen tends to get clogged with large sized particles. The present invention provides an ultrasonic probe that periodically cleans the screen when the pressure within the milling chamber reaches a predetermined value.
