众所周知,对大于13毫米粒级的块煤,用重介分选机、跳汰机都能有效地处理,而对小于13毫米粒级的末煤,则可选用重介旋流器、末煤跳汰机、平面摇床等方法处理。平面摇床处理量小,体积大,一般很少采用。重介旋流器选末煤,效率虽然高,但流程比较复杂,加工成本较高。成本高的原因有如下几个方面: 1、为保持悬浮液粘度低和分选效率 It is well-known that for lump coal above 13 mm, heavy medium separator and jig can all be effectively treated, whereas for the end coal below 13 mm, heavy medium cyclone, Jig, flat shaker and other methods to deal with. Plane shaker processing capacity is small, large, generally rarely used. Dense medium cyclone election at the end of coal, although the high efficiency, but the process is more complex, higher processing costs. The reasons for high cost in the following areas: 1, in order to maintain low viscosity and suspension sorting efficiency
