摘要: 针对水力旋流器在选煤厂煤泥水分级浓缩中普遍存在溢流跑粗或底流夹细的问题,分析了煤泥的密度、沉降末速、等沉比等几个因素对水力旋流器分级效果的影响,认为颗粒密度对分级过程中有一种分选副作用,并提出了一些提高分级效果的建议。

Abstract: Hydrocyclone has been widely used for coal slime classification ever since its invention. However, there is a limitation to hydrocyclone accuracy: even though much work has been done to improve its structural and operational parameters, there are still misplaced particles in underflow and overflow. It’s shown that particle density has a role in sizing effect by analyzing terminal velocity, equal settling ratio and density. This can be thought of as separation side effect and some suggestions about how to improve classification efficiency was be put forward.
