<p>[Problem] To provide a pulverizer wherein the temperature of the inner surface of the liner can be efficiently adjusted. [Solution] The pulverizer (10) is provided with: a rotator (15); striking members (16) installed on the rotator (15) for colliding with brown coal (13); collision plates (20) disposed around the rotator (15); and liners (30) provided on the inner surfaces (21) of the collision plates (20) and having an inner surface (31) onto which brown coal (13) that has collided with the striking members (16) is thrown. The pulverizer (10) also is provided with a temperature adjustment mechanism (40) for adjusting the temperature of the inner surface (31) of a liner (30). The temperature adjustment mechanism (40) is configured so as to be capable of adjusting the temperature of the liner (30) further to the inside than the inner surface (21) of the collision plates (20).</p>
