PROBLEM TO BE SOLVED: To solve the problem of a crusher that vibration occurs by impact and intense noise is emitted when a matter to be treated is crushed with a rotary blade and a fixed blade which are driven by a motor being the driving source. SOLUTION: The crusher which has a rotor 13 of a large moment of inertia and a rotary shaft 5 of high impact resistance and which emits only small vibration and noise in crushing operations can be obtained by making the shape of a motor 6 flat, attaching a weight 14 to the rotor 13, and fixing the motor 6 so that the center of gravity of the crusher is raised to the level of the crushing part. |
