Abstract

The invention relates to the cement production and may be utilized for the raw cement mixture heat processing by means of the dry process. The purpose of the invention consists in the process intensification. In the prior claimed process the gases are directed from the rotation furnace to the multicyclic on the material in front of the calciner. Then the evacuation gases from the calciner are mixed with the gases from the multicyclic heat exchanger and are directed in two equal fluxes to the multicyclic heat exchangers branches.
