A low-resistance powder concentrator rotor structure, a rotor upper cover plate, a rotor middle plate and a rotor lower cover plate are arranged from top to bottom on the outside of a rotor shaft sleeve and a rotor cone, the rotor upper cover plate and the rotor middle plate are connected with the rotor shaft sleeve or the rotor cone through a rotor connecting plate, and the rotor lower cover plate is directly connected with the rotor cone; a plurality of inclined grooves are formed on the rotor upper cover plate and the rotor middle plate; the rotor connecting plates are arranged in pairs, have the same shape and are symmetrical about the rotor axis; the shapes of the adjacent two rotor connecting plates are different, the included angles with the horizontal plane are different, and the rotor connecting plates are arranged in the form of vertical plates, so that the high-speed airflow in the rotor cage is hindered and scattered. The present application interferes with the generation of the resistance surface of the connecting part position by the special connecting plate and vertical rod arrangement, so that the number of the connecting parts in the same plane or cone surface is small, the ventilation cross-sectional area is increased, and the power consumption of the vertical mill system fan is reduced.
