复合型ZZDD种分结晶助剂在氧化铝工业生产中试用的结果表明,该添加剂具有显著的强化附聚过程、促进晶体生长、降低产品磨损系数的作用。工业试验结果表明,平均粒径增加了9μm、-45μm减少了9.9%、磨损系数降低了6.3%,同时能明显地减少结疤、改善过滤效率、提高焙烧产能,为我国氧化铝生产实现砂状化提供了一种简单方便、切实可行、卓有成效的解决途径。
The results of the trial of composite ZZDD seed crystallization aid in industrial production of alumina show that the additive has significant strengthening agglomeration process, promoting crystal growth and reducing the wear coefficient of the product. Industrial test results show that the average particle size increased by 9μm, -45μm decreased by 9.9%, the wear coefficient decreased by 6.3%, while significantly reducing scarring, improve the filtration efficiency and improve roasting productivity, to achieve sand production of alumina Provides a simple, practical and fruitful solution.
