<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a burned material where the burned material having a large density and mechanical strength, having the uniform properties of a particle size and the like and being suitable as civil engineering resources such as an artificial aggregate, backfill and the like can be manufactured efficiently even when raw materials having an unsteady chemical composition such as industrial wastes, general wastes, construction waste soil, sediment and sludge are used. <P>SOLUTION: The method for manufacturing the burned material comprises a raw material preparing step (A) to obtain a concoction by adding a CaO source to raw materials consisting of one or more kinds selected from among industrial wastes, general wastes, construction waste soil, sediment and sludge and by controlling a hydraulic modulus of 0.1-1.0, an inhibitor removing step (B) to remove inhibitors such as unburned carbon and the like having the possibility of lowering the quality of the burned material when burnt in a step (C) by diffusing the concoction in hot wind in a preheater 2 attached to a rotary kiln 3 and the burning step (C) to obtain the burned material by feeding the concoction in which inhibitors are removed in the rotary kiln 3 and by burning it. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
