Coal crushing assembly with thermal drying function

The coal crushing assembly with the hot drying function comprises a first crushing unit and a second crushing unit, the first crushing unit comprises a first rotating shaft and a first crushing part arranged on the first rotating shaft, and the second crushing unit comprises a second rotating shaft and a second crushing part arranged on the second rotating shaft. Coal briquettes are extruded and crushed when the first crushing part and the second crushing part rotate oppositely; the first rotating shaft and the second rotating shaft are each provided with a heat drying channel which is through in the axial direction and used for transmitting a heat medium. According to the utility model, the two rotating shafts which rotate relatively are adopted to drive the staggered crushing teeth to crush coal briquettes, and meanwhile, the hot drying channels through which a heat supply medium passes are formed in the rotating shafts, so that the rotating shafts can heat and dry the coal briquettes while rotating to crus
