The purpose of saving water is to study whether the slag treatment technology of rotary drum method can be used to treat the blast furnace slag.The blast furnace slag enters the drum through the slag flushing ditch of the granulation tower,and the slag-water separation is carried out through the drum,then the blast furnace slag is separated from the rotary drum by increasing the length of the slag ditch,using the method of extremely fast water flow and water quenching of the punching box,and analyzing the slag water ratio and ton water consumption rate,it can be clearly concluded that this project using the rotary drum blast furnace slag treatment technology,the slag-water ratio and ton water consumption rate have been significantly optimized.This project conducts technical research on the blast furnace slag treatment method by improving the drum method slag treatment technology,to achieve the purpose of saving water and energy,which meets the requirements of national sustainable development,for your reference.
