The invention discloses a three-product lump coal sorting device. The three-product lump coal sorting device comprises a lump raw coal sorting track arranged on a support, a lump coal distributor arranged above one end of the lump raw coal sorting track, an electromagnetic baffle which is rotationally connected to the bottom of the other end of the lump raw coal sorting track, a clean coal channel, a middle coal channel and a gangue channel which are arranged below the electromagnetic baffle; the electromagnetic baffle is controlled by an electromagnetic baffle controller to be horizontally arranged and 90-degree opening and closing are carried out in the vertical direction so as to enable the clean coal, the middle coal and the gangue respectively fall into the clean coal channel, the middle coal channel and the gangue channel; and the three-product lump coal sorting device further comprises a knocking system, a sound collecting device, a filtering/noise reduction device, a sound characteristic analysis device, a PLC and an upper computer which are fixed above the lump raw coal sorting track. Compared with the prior art, the method can realize dry separation, the dependence on water is reduced, and the separation of lump coal in the arid region can be solved; the equipment is small in size and low in energy consumption, and the sorting precision and the automation degree of the raw coal are improved.
