ABSTRACT:
A method and device for sintering materials and, in particular, limestone gravel, of very different granular size in the granular range of 5 to 50 mm, in a rotary shaft kiln with a shaft preheater and shaft cooler, are provided wherein the sintering charge of the original gravels are crushed into two or more granular fractions and are fed in a low band width to the furnace system periodically and alternately, and wherein the process gases flow through the filling or charge layers of the sintering materials. The filling layers are automatically changed in the shaft preheater and the shaft cooler in their thickness, so that the flow through resistance thereof remains constant.
