解放以来,我国相继研制出一些细泥重选设备,尤其是60年代初期,离心选矿机问世,标志着细粒重选设备研制进入了一个新的阶段。随后在研制连续、大型离心选矿机的同时,为使其配套设备跟上去,先后研制出用于细泥精选的皮带溜槽、振摆皮带溜槽。后者因结构复杂,未能在工业上推广应用。目前,最引人注目的 Since the liberation, China has developed a number of fine mud re-election equipment, especially in the early 1960s, centrifugal concentrator came out, marking the development of fine grain re-election equipment has entered a new stage. Followed by the development of continuous, large-scale centrifugal concentrator at the same time, in order to keep up its ancillary equipment, has developed a fine selection of fine chute chute, chute belt chute. The latter due to the complex structure, failed to promote the industrial application. At present, the most striking
