Abstract
Crystallization of a melt is induced by causing the melt to flow downwardly in a gap which is defined by upwardly moving cooled walls so that crystallate adheres to the walls and is carried upwardly for recovery. The walls are formed by endless belts which are cooled by fluid sprayed from nozzles. The walls are adjustable so as to be parallel or upwardly divergent.
