PROBLEM TO BE SOLVED: To provide a pulverizer capable of being easily opened and detached without complex operations such as horizontal movement of an opening door while a stationary blade installed on the inner surface of the opening door can be surely engaged with a rotary blade or a rough-crushing blade. SOLUTION: This pulverizer pulverizing materials to be pulverized by co-operation of the rough-crushing blade 10, the rotary blade 20 and the stationary blade 30 installed in a housing H, and discharging the pulverized materials through a discharge opening 40 formed in the lower side of the housing H, comprises tie-rod shafts 3 built across the lower ends of front and back walls 1, 2 so as to keep a predetermined interval between the front and back walls 1, 2, and right and left opening doors 4, 5 opening down toward outside with the above lower ends as supporting points. At the lower ends of the opening doors 4, 5, bearing parts 7 are formed, which are journaled to the front and back walls by pivot shafts 6 different from the tie-rod shafts 3, and the pivot shafts 6 are installed at the sides inner than the tie-rod shafts 3.
