Title:
鉄鋼スラグの湿式分級設備
Document Type and Number:
Japanese Patent JP5321845
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide equipment which when steel slag is crushed and sized, efficiently removes and classifies fine powder sticking to a steel slag surface.SOLUTION: Wet classification equipment for steel slag includes wet sieves 14, 16 for classifying crushed and sized steel slag and a wet cyclone 18 for centrifugally separating particles having a smaller particle size and a smaller specific gravity than undersize particles through the wet sieves 14, 16 from the sieved particles. Since fine powder sticking to a steel slag surface is efficiently classified with the wet sieves and the wet cyclone, it is not necessary to carry out sieving again. Iron-containing steel slag can be subjected to efficient classification and separation into slag and iron.
