摘　　要：斜窄流分级机是一种新型高效的重力分级设备，为更好地掌握设备性能，本研究将理论计算与该设备的应用实践相结合，分析了斜窄流分级机的分级效率与矿粒粒度及密度的相关性。分析指出，斜窄流分级机处理分级粒度为0．02—0．1mm的高密度物料时分级效率最高。在攀钢选钛厂给矿矿浆分级作业中，分级粒度和密度分别为0．063mm及3．9×10^-3g／mm^3，斜窄流分级机的分级效率高达79．70％。Inclined narrow flow classifier is a new efficient gravity classifying device. To better control the equipment performance, the paper, by combining the theoretical computation and the equipment application practice, analyzes the correlation of the efficiency of inclined narrow flow classifier with the feed particle size and density. The analysis indicates that the best classification efficiency of the equipment occurs when treating high density materials at a classification size of 0. 037 - 0.1 mm. In its application in treating feed pulp in Pan Steel＇s Titanium Concentrator, the classification efficiency is as high as 79.70% at a classification size of 0.063mm and a density of 3.9 × 10 ^-3 g/mm^3.
