[0018] A comprehensive treatment method for blast furnace dust removal ash, including the following process steps:
[0019] (1) The blast furnace dedusting ash falls from the receiving bin via the pendulum feeder onto the belt of the belt conveyor. At the end of the belt conveyor, there is a water feeding hopper. After the blast furnace dedusting ash is added with water, the Just flow) Take water as the carrier and spirally enter the wet ball mill for ball milling. (The wet ball mill can not only complete the mixing effect, but also grind the hard shell formed by coating the iron-containing material of the dust ash, coal powder, ash, and acid-alkaline flux to improve the quality of the final product.) The blast furnace dust ash is in the ball mill After being fully mixed and finely ground, it overflows the ball mill and enters the discharge chute.
[0020] (2) The blast furnace dust slurry after ball milling naturally flows into the primary magnetic separator from the discharge ch...
