Abstract

PURPOSE:To carry out saving of resource and energy by burning a composite material containing a glass component and a resin component and a cement clinker raw material. CONSTITUTION:A cement clinker raw material is mixed with 0.1-60wt.% of a composite material containing 10-60wt.% of a glass component and a resin component and having <=500mum maximum length to provide a mixture. The mixture is heated by a burner 4 and fed from a feed inlet 2 into an inclined rotary kiln 1 in a feeding direction (a) to burn the resin component and a part of thermally decomposed gas is introduced from a discharge port 5 into a secondary burning furnace 6 to completely burn the gas. On the one hand, the cement clinker raw material containing the glass component is burned and discharged from the discharge port 3 and cooled and solidified to provide the objective cement clinker.
