PROBLEM TO BE SOLVED: To promote the biting-in action of a crushing blade by restraining the escape of a material to be crushed due to the rotation of a crushing rotor and to enable easily maintenance services such as replacement of the crushing blade of a fixed blade, cleaning of a screen or an operation chamber or the like. SOLUTION: This crushing machine 1 is structured of a casing 20 which has a supply opening 21 for the material to be crushed W and also a table 24 for forcibly supplying the material to be crushed to an internal crushing operation chamber 22, the crushing rotor 10 which is driven to rotate in the crushing operation chamber 22 and is equipped with the crushing blade 12 for crushing the material W collaboratively with the fixed blade 25 and a pusher 30 for forcibly supplying the material W to the crushing operation chamber 22 over the table 24. In addition, a mobile forward part 20A to be opened by a hydraulic cylinder C3 is equipped with a pressing member 35 which presses the material W from above the crushing operation chamber to the crushing rotor 10 by the reciprocating motion of a cylinder C2 during a crushing operation and a screen 40 for adjusting the grain size of the crushed material.
