ABSTRACT:
The invention relates to a process and an apparatus for the granulation of granulatable and/or pelletizable substances in which the substance to be granulated is introduced in the form of a closed jet into a rapidly flowing refrigerant--preferably liquid nitrogen. This purpose is served by a vertically arranged reaction tube (2) into the upper part of which the jet enters and through which the refrigerant circulates by means of a transport element (7).
