The present invention relates to a system and method for the heat treatment of finely divided materials, such as those used in the manufacture of cement. In the improved system of the present invention, two rows of suspension gas heat exchanges are provided, each row including a plurality of cyclone separators. A calcination furnace is connected to one of the rows, and a material cooler is connected to the other of the rows. In a preferred form of the invention, the row connected to the calcination furnace has at least one cyclone separator less than the row connected to the material cooler. A combustion device is also provided in conjunction with the material cooler to make more efficient use of the calcination furnace.
