The invention discloses a novel efficient mixing crusher. The mixing crusher comprises a cylinder body, a rotary shaft and a rotating shaft, the rotary shaft is arranged at the central axis of the cylinder body, and a radial crushing knife perpendicular to the rotary shaft is fixed to the rotary shaft; a groove is formed in the inner wall of the cylinder body, and a supporting ring is fixed to theouter side of the cylinder body; the rotating shaft parallel to the cylinder body is arranged on the lower side of the cylinder body, a rotating wheel is arranged on the rotating shaft, and the rotating wheel is in contact with the outer side of the cylinder body. In general, the mixing crusher has the advantages of being reasonable in structural design and convenient and fast to install and use,no dead corner exists in the crushing process, the crushing and mixing efficiency of biomass materials can be effectively improved, the production efficiency is improved, the uniformity of fertilizeris improved, and the mixing crusher has the advantage of being extremely high in use value.
