Method for manufacturing alumina substitute raw material for cement using aluminum waste dust collection dust and alumina substitute raw material for cement produced thereby

摘要

The present invention removes the salt and impurities contained in the aluminum waste dust collection dust and provides it as an alternative raw material to replace alumina included in the manufacture of cement, thereby preventing environmental pollution and increasing added value. It relates to a method for manufacturing alumina substitute raw material for cement and to alumina substitute raw material for cement produced thereby, 50 L of water at a temperature of 50 to 60 ° C and 10 kg of aluminum waste dust collection dust are put into an exclusive stirrer and stirred at a speed of 40 to 120 rpm to remove impurities inside the dedicated stirrer (H 2 O 2 ) 1.5 A first stirring step (S100) of stirring for 100 to 150 minutes after inputting 2.5L, and a first draining and dehydrating step of draining and dehydrating the liquid material that was put into the dedicated stirrer after the first stirring and removing it (S200) and 50 L of water at a temperature of 50 to 60 ° C after dehydration is added to the dedicated stirrer and stirred at a speed of 40 to 120 rpm while ammonium hydroxide (NH 4 OH) to reduce the salt content inside the dedicated stirrer A second stirring step (S300) of stirring for 100 to 150 minutes after adding 0.7 to 1.5 L, and a second draining and dehydration step (S300) of draining and dehydrating the liquid material that was put into the inside after the second stirring and removing it ( S400) and a water removal step of removing water so that the water content is 5 to 20% or less by putting the aluminum waste dust collecting dust in the sludge state obtained in the secondary drainage and dehydration step into a vacuum belt filter or a ceramic disk filter (S500) ) and a packaging step (S600) of packaging by weight (g) unit after removing the moisture.
