摘　　要：研制了一种集浮选和分级于一体的浮选分级机,工作原理是在一个装置内联合实现浮选、泡沫分选、水力分级以及收缩槽内分选的过程。通过对设备的操作条件进行试验研究,确定了设备操作的最优条件,设备结构设计巧妙合理,处理某铁尾矿再选精矿达到了较理想的浮选和分级指标,经浮选分级后,抛掉产率约18%、品位为11%的尾矿;得到了产率为41.67%、品位为24.71%的底流产品,为进一步研制工业型浮选分级机提供了基础数据和实施的可行性。A set of flotation classifier uniting flotation and classification was developed,of which the working principle was combined with flotation,froth baffle separation,hydraulic classification and contraction groove sorting in a device. Due to the ingenious and reasonable design of the equipment,an ideal flotation and classification index was obtained under the optimal conditions of equipment operation,which were determined by experiment test. After flotation and classification,the tailings（ yield 18% and grade 11%） and underflow products（ yield 41. 67% and grade 24. 71%）were discarded and collected,respectively. This study provided the basic data and the implementation feasibility for the further development of industrial type flotation classifier.
