So The graduation project Designed a production line of 600 000 t/a super fine slag. By seeing about, we chose the vertical technology and determined the quality
4、indexes and process parameters after comparing the grinding efficiency, energy consumption and final cost of vibromill, ball mill, rolling press and vertical mill. By comparing the use of roller mill at home and abroad and scale, vertical mill system used abroad, but also compared several vertical mill of foreign production and use, selection of the German Loesche produced LM46.2 +2. I design and calculate the slag burden plan, material balance, main engine balance, storehouse balance, heat b
