Method for the treatment of finely grained material, particularly for the precalcining of cement |
摘要 |
A method and mechanism for calcining cement wherein the material is preheated in a precalcining zone and a vertical conduit leads heated discharge gases upwardly from a main calcining furnace, a supply of fuel and a supply of oxygen is fed to a preoxidation zone beneath the precalcining zone and raw material is fed into an admixing area above the burner with a deflector preventing particles from falling down into the preoxidation zone with the fuel being partially oxidized so that controlled heating and controlled oxidation occurs in the precalcining zone.
