Abstract
Method and apparatus for the heat treatment of fine-grained material, particularly raw material for the manufacture of cement wherein the material is pre-heated, calcined, sintered, and then cooled, the sintering of the substantially calcined material according to the present invention being carried out in the form of an airborne suspension.
Claims15
In a method for heat treating a fine-grained material in which said material is sequentially passed through a pre-heating zone, a calcining zone, a sintering zone, and a cooling zone, the improvement which comprises separately heat treating the calcined material from said calcining zone to volatilize lower melting components, suspending the substantially calcined and heat treated material as an airborne suspension in said sintering zone and sintering the suspension in said sintering zone.
