Description/Abstract An installation for the thermal treatment of a pulverant mineral product by gases has a support frame at a first level, a furnace for the thermal treatment of the pulverant mineral product in suspension in hot gases generated by the combustion of air and a fuel, two groups of series-connected cyclones connected to the furnace, one of the groups of cyclones being arranged upstream of the furnace and the other group of cyclones being arranged downstream of the furnace, and conduits connecting the cyclones to each other and to the furnace so that exhaust gases from the furnace pass successively through all the cyclones of the one group while a current of air passes through all the cyclones of the other group before entering the furnace to serve as the combustion air, the exhaust gases heating the product before it enters the furnace and the air current cooling the treated product.^The furnace and two of the cyclones located, respectively, immediately upstream and immediately downstream of the furnace are mounted on the support frame at the first level.^A superstructure is affixed to the support frame and supports the remaining cyclones at a second level higher than the first level.
