摘要: 介绍了水力分级旋流器在我国的引进发展历程,阐述了其在粗精煤泥回收工艺中的作用。通过对水力分级旋流器各产品指标分析,得出由于颗粒等沉比的存在,必然导致同粒级物料轻、重产品错配,俗称“反分选”作用,进而导致粗精煤泥产品易于超灰。提出采用气动击打振动翻转弧形筛替代水力分级旋流器,方可解决该工艺中粗精煤泥灰高的问题。

Abstract: This paper introduces the introduction and development process of hydraulic grade cyclone in China, and expounds its function in the recovery process of coarse clean coal slime. Through the analysis of the product specifications of the hydrocyclone, that due to the particles sink ratio exists, will inevitably lead to the same particle materials of light and heavy products mismatch, commonly known as the "anti separation effect, resulting in coarse coal slime ash super easy products. The fine seam pneumatic impact sieve instead of the hydrocyclone, which can resolve the coarse coal in the process, the problem of high marl.
