ABSTRACT:
A process for the operation of a counter current crystallization column is described in which perforated plates or screens are positioned at spaced intervals. Movable objects such as steel balls or plastic balls are inserted in the column on each of the plates or screens and set into vibration by some kind of distance effect such as vibration of the entire column. The vibrating objects promote the passage of the crystals through the plate in that they have a milling effect on the crystals and are drumming against the plates. When said effect is wanted at the under side of the plates, supporting screens are mounted just below the plates and provided with the movable objects.
