The invention discloses a material distribution device of a novel fine crusher. The material distribution device comprises a housing, a speed reduction motor, a roller and spoke plates, wherein the roller is arranged in the housing and driven by the speed reduction motor, and the spoke plates are detachably and uniformly arranged along the periphery of the roller. The material distribution device disclosed by the invention adopts the detachable spoke plate type roller and multi-working position regulation and variable-frequency speed reduction type drive so as to overcome the defects of low circulation capacity, easiness in causing coal blockage, poor regulation capacity of coal flow and the like of an old cushioning device. The material distribution device further has the advantages of simple structure, convenience in use, easiness in operation, convenience in maintenance and overhaul and the like, and can better control the motion state of materials under various conditions and realize optimal operation working conditions of the fine crusher. The device can be applied to not only coal crushing systems of large and medium-sized thermal power plants, but also bulk material crushing systems in coal, metallurgy, mining, building materials and other industries, and further has a wide range of applications and good development prospects.
