METHOD FOR MANUFACTURING C12A7-BASED MINERALS USING A ROTARY KILN CAPABLE OF SAVING ENERGY AND REDUCING THE GENERATING AMOUNT OF CARBON DIOXIDE

摘要

PURPOSE: A method for manufacturing C_12A_7-based minerals using a rotary kiln is provided to shorten manufacturing processes using a cement sintering furnace without the formation of a pellet before a sintering process.;CONSTITUTION: A method for manufacturing C_12A_7-based minerals includes the following: A mixture is obtained by mixing a calcium oxide supplying source and an aluminum oxide supplying source. The mixture is sintered in a rotary kiln at a temperature between 900 and 1500 degrees Celsius. The calcium oxide supplying source is one or more selected from limestone, quicklime, calcium hydroxide, marble, marl, and waste lime. The aluminum oxide supplying source is one or more selected from bauxite, aluminum hydroxide, aluminum dross, and a spent oil-refining catalyst.;COPYRIGHT KIPO 2012
