The invention discloses a high-quality biomass fuel processing device. The high-quality biomass fuel processing device comprises a shell. A first funnel is arranged on the upper side of the shell. The shell is internally provided with a second funnel, and a horizontal rotary rod is arranged on the side, close to the first funnel, of the second funnel. Hammer pieces are arranged on the side wall of the rotary rod at equal intervals. The two ends of the rotary rod are provided with first antifriction bearings which are arranged on the shell. An adsorption roller and a smashing roller are arranged on the side, far away from the rotary rod, of the second funnel. The two ends of the adsorption roller and the two ends of the smashing roller are provided with second antifriction bearings which are arranged on the shell. Protruding tooth tips are arranged on a cutting roller. A magnetic rod is arranged on the inner side of the adsorption roller, and an oblique plate is arranged on the side, far away from the smashing roller, of the adsorption roller. The high-quality biomass fuel processing device is simple in structure, the feeding speed is effectively controlled, a feed port cannot be blocked, the smashing effect is good, the service life of the smashing roller is long, meanwhile, iron sundries are cleared away in time, and the fuel processing quality is good.
