There is provided crusher which can produce uniform finely pulverized material without having to increase the speed of a rotor (1) and which has a good rate of productivity. The crusher comprises crushing vanes (3) having extensions (35) formed protruding radially from the outer surface of the rotor (1) and extending below a material drop point of a dead bed, and an annular wall (5) similarly positioned below the material drop point of a dead bed, on an inner rim of a lower plate (22) of a crushing chamber (2), and pulverizing is effected by crushed material which rebounds and falls from the dead bed, striking the extensions (35) of the crushing vanes (3).
