The invention provides a homogeneous blending process method for mixed coal of power coal. The homogeneous blending process method comprises the following steps: S1, cleaning anthracite and bituminous coal; s2, drying the cleaned anthracite and bituminous coal; s3, mixing the power coal according to the proportion; s4, performing crushing treatment on the anthracite and the bituminous coal; s5, crushing the mixed power coal again; s6, mixing the power coal into blocks; the invention relates to a device for homogenizing and blending power coal. The device comprises a mixing bin, a cage type roller, a shell belt feeder, a tooth roller mixer, a belt conveyor, a finished product bin, a loading chute and a chute elevator, by mixing anthracite, bituminous coal, biomass, enteromorpha and alkaline earth metal, the combustion degree of power mixed coal is improved, heat is increased, ignition and burnout are easier, emission of CO2 and SO2 is remarkably reduced, slag bonding and contamination to a hearth are relieved,
