ABSTRACT:
A process and mechanism for thermally treating fine ground material for the calcining of cement in stages which passes finely ground calcareous and argillaceous material into a vertical chamber to enter a deacidifying zone, supplying fuel to the vertical chamber with a supply of oxygen so that the fuel is partially oxidized prior to mixing with the material and the fuel, oxygen and material are supplied so that the material is deacidified in the range of 50% to 80%, passing exhaust gases from a kiln into the deacidifying zone, and passing material from the deacidifying zone through a cyclone separator to separate the gases and deliver the preheated material to the kiln for completion of the burning process.
