Steel slag multistage crushing and grinding ultrafine powder preparation device and method
The invention relates to a steel slag multistage crushing and grinding ultrafine powder preparation device and method. The device comprises: a steel slag tailing bin (1), a rod grinding slag breaker (2), a first belt line (3), an electromagnetic roller iron remover (4), a first magnetic separation powder bin (5), a double-roller slag breaker (6), a disc magnetic separator (7), a second magnetic separation powder bin (8), a second belt line (9), a vertical slag grinder (10), a powerful magnetic separator (11), a third magnetic separation powder bin (12), a bucket elevator (13), a hot blast stove (14), a dust collector (15) and a finished product warehouse (16). With the multistage crushing and magnetic separation treatment process, the granularity of the steel slag tailings and the contentof iron elements such as metallic iron in the steel slag tailings are gradually reduced, the grinding power consumption of the steel slag is greatly reduced, and the activity index of the steel slag ultrafine powder is remarkably improved; meanwhile, the recycling of iron resources is efficiently realized, and the resource utilization value of the steel slag is systematically improved.
本发明涉及一种钢渣多级破磨超细粉制备装置及方法，所述装置包括：钢渣尾渣仓(1)、棒磨破渣机(2)、1号皮带线(3)、电磁滚筒除铁机(4)、磁选粉1仓(5)、对辊破渣机(6)、盘式磁选机(7)、磁选粉2仓(8)、2号皮带线(9)、立式磨渣机(10)、强力磁选机(11)、磁选粉3仓(12)、斗式提升机(13)、热风炉(14)、除尘器(15)和成品仓(16)，采用了多级的破碎、磁选处理工艺，逐步降低了钢渣尾渣粒度和其中金属铁等铁元素含量，大幅度降低了钢渣粉磨电耗，显著提高了钢渣超细粉活性指数，同时高效的实现了铁资源的回收利用，系统性的提升了钢渣资源化利用价值。
