摘　　要：旋流细筛与传统的重力沉降槽比较,分级效率高,砂状氢氧化铝品级率也高:一台设备分级同时得到粗、中、细三种产物,简化了分级流程;设备结构简单、处理能力大,降低了基建与生产费用。贵州铝厂已采用此项分级技术,年经济效益125万元以上,山西铝厂等也将相继采用。Cyclo-Fine Screen(CFS)shows higher classification efficiency than traditional Gravitarional Setting Vessel(GSV),resulting in improved quality of sandy aluminium hydroxides of first and second classes from 60.56% in the case of GSV up to 92.48% with the introduction of CFS. Moreover,classification circuit can be simplified because CFS can yield three pro- ducts:coarse,medium and small sizes.CFS has simpler structure and higher through- put,so the capital investment and production costs are reduced.
