Verfahren und Vorrichtung zur Stofftrennung durch Kristallisation von Schmelzen

摘要

A process and device are disclosed for separating substances by crystallization of molten material. In order to bring about crystallization, the molten material is fed into the gap between two opposing moving walls which can be cooled; the walls move upwards in the same and substantially vertical direction, and the molten material is introduced into the gap from above in the direction opposite to the direction in which the walls move.
