KHC型斜槽分选机是苏联固体燃料精选研究所在研究倾斜上升液流中重力作用的基础上研制出来的。该设备洗选末煤、块煤和不分级煤均能得到良好的分选效果,而且生产能力很大。1974年,KHC分选机开始在生产上使用。其使用情况如表1所示。用KHC分选机洗选杂煤,大大地减少了煤在矸石中的损失。如安格林斯基露 KHC-type chute separator is the Soviet Union Institute of solid fuel selection in the study of the rising tilt of the gravity flow on the basis of the developed. The equipment washing the end of the coal, lump coal and non-graded coal can get good sorting results, but also great production capacity. In 1974, KHC sorting machines began to be used in production. Its use as shown in Table 1. Use KHC sorting machine washing mixed coal, greatly reducing the loss of coal in the waste rock.
