To provide a pulverizing apparatus which is equipped with a novel crushing mechanism (a crushing means) and which is suitable for production of recycled soil (improved soil).

The pulverizing apparatus is equipped with a pulverizing tower and a pulverizing means arranged inside the crushing tower. The pulverizing tower 11 is equipped with a matter to be pulverized charging port 134 at an eccentric position of a ceiling section and an pulverized matter discharging port 144 at a bottom side. The pulverizing means is constituted of one or a plurality of rotary planar bodies 152 for centrifugally releasing the matter to be pulverized (a raw material), a vertical reflecting wall surface 121 for reflecting the centrifugally released matter to be pulverized in an inside direction and a plurality of pulverizing chains 153, each of which is made of a rigid body, hangs inside the reflecting wall surface with a lower end as a free end and can pivot.
