Abstract

The utility model relates to a composite vertical shaft impacting crusher that integrates impact crushing and hammer crushing. Materials enter a crushing chamber from a feeding hopper, fall onto a material distribution cone on the top of a rotor, and are impacted and crushed by the material distribution cone rotating in high speed. The accelerated crushed materials fly toward an impact plate for secondary impact crushing and are hammered by a striking plate fixed on the rotor when the crushed materials rebound and move down under gravity. The crushed materials are stricken toward the impact plate for impact crushing once again. Materials which are crushed repeatedly move in a Z-shaped course in the entire crushing chamber and are discharged from a discharging hopper after crushed.
