随着羰基铁粉市场的细化,市场需要粒度更小、分布区间更窄的羰基铁粉,为满足这一需求,我们做了大量市场调研,根据羰基铁粉特性与流能粉体设备有限公司合作研发成功了国内首台用于羰基铁粉的氮气保护涡流分级机。本文在兴化涡流分级机研发的基础上,介绍了涡流空气分级机的工作原理和发展过程,对不同类型的涡流空气分级机进行了分析对比。简要介绍了兴化在选型与研发、改造涡流分级机的过程中取得的经验和效果。 With the refinement of the carbonyl iron powder market, the market needs carbonyl iron powder with smaller particle size and narrower distribution range. To meet this demand, we do a lot of market research. According to the characteristics of carbonyl iron powder and limited equipment of flow energy powder The company successfully developed the first nitrogen vortex protection classifier for carbonyl iron powder in China. Based on the research and development of Xinghua vortex classifier, this paper introduces the working principle and development process of vortex air classifier, and analyzes and compares the different types of vortex air classifier. Briefly introduces the experiences and effects of Xinghua in the process of selecting and developing, rebuilding the vortex classifier.
