The invention discloses carbon fiber smashing equipment. The carbon fiber smashing equipment is mainly composed of a supplied material conveyor, a cut-off machine, a coarse pulverizer, an atomizer mill, a screening machine and a finished product conveyor as well as a cyclone separator and a pulse dust collector which are connected through a corresponding air conveying pipeline. The equipment can produce carbon fiber products with multiple lengths and finenesses, the highest fineness can achieve 300 meshes, the annual output can achieve 1000 tons, and the requirements of carbon fiber sections and thin powders of different specifications required by a carbon fiber production processing industry are fully achieved. The carbon fiber smashing equipment disclosed by the invention has the characteristics that the property is good, the efficiency is high, the structure is compact, the floor space is small, the yield is high, the operation is convenient, the smashing fineness is adjusted, the carbon fiber smashing equipment is wear-resisting and is easy to maintain, the labor is saved, the electricity is saved, and the environment can achieve the standard; the carbon fiber smashing equipment is ideal carbon fiber smashing equipment instead of imported equipment.
