摘要

Process for the heat exchange between a fine granulation material and a gas stream and heat exchanger for carrying out the process, especially for the previous heating, calcination and testing of crude cement flour, by means of kiln exhaust gases, characterized in that the gas prints a current movement in the form of a swirling depression and the fine granulation material, to be put into heat exchange with the gas, mixes the gas in the vicinity of the swirl core so that the turning motion with the gas moves out against the radial component of the gas velocity under heat exchange with the gas and can then be collected again.
