摘要：针对普通开流氧化铁管磨机在氧化铁生产过程中存在电耗高、流速快、料球比低、严重糊磨等问题,通过在磨内设置高效筛分装置,采用料位调节、微型钢段等技术措施,极大地改善了磨内粉磨工况,提高了粉磨效率。该技术在工业生产中得到应用,它能提高台时产量30%以上,降低粉磨电耗25%以上,并大幅降低钢材的消耗。

Abstract: To comnter the problem of high grinding energy , rapid flow of material , low ratio of meterial to grinding media , and bad ball coating in common open circuit ferric oxide tube mill, ferric oxide superfine grinding technology markedly increase grinding efficiency and improve grinding status in the tube mill by setting high efficiency sifting equipment, material place regulating technology and subminiature cylpeb. The technology have been proved in practice that it can promote output capacity more than 30%, reduce gringing enercy more than 25%, and reduce steel consume by a wide margin . 

Keywords: ferric oxide; superfine grinding ; grinding efficiency
