When the driving motor (1) rotates, the output end of the eccentric shaft (2) can rotate relative to the output shaft of the driving motor (1) by a fixed eccentricity. The supporting platform (3) is fixedly connected with a flange of the driving motor (1) through a bolt and a spigot, and the center of the supporting platform (3) is ensured to be coaxial with the rotation center of the driving motor (1). The oscillating bearing (5) is used for connecting the output end of the eccentric shaft (2) with the fixed grinding disc (6) so as to enable the fixed grinding disc (6) to generate eccentric rotation relative to the rotation center of the driving motor (1). The grinding end cover (7) is fixed on the fixed grinding disc (6). The movable grinding disc (8) is positioned in a closed space formed by the fixed grinding disc (6) and the grinding end cover (7). The height of the closed space is slightly larger than that of the movable grinding disc (8), so that a sliding gap exists when the movable grinding disc (8) slides in the closed space. When the fixed grinding disc (6) rotates eccentrically, the movable grinding disc (8) and the fixed grinding disc (6) move relative to the fixed grinding disc (6) through the friction force of the contact end faces, so that the fixed grinding disc (6) and the movable grinding disc (8) are impacted, and materials in the fixed grinding disc (6) are ground and crushed. The cross slide rail (9) can enable the fixed grinding disc (6) and the supporting platform (3) to move mutually in the horizontal X, Y direction, but limits the movement of the fixed grinding disc (6) relative to the supporting platform (3) in the vertical Z direction and the rotation of the fixed grinding disc (6). When the driving motor (1) rotates, the fixed grinding disc (6), the grinding disc end cover (7) and the movable grinding disc (8) can rotate horizontally and eccentrically around the rotation center line Z1 by the common center of mass M1 and the fixed eccentricity of the eccentric shaft (2), and the eccentricity can not change along with the change of the number of revolutions of the motor. And the cross slide rail (9) limits the rotation of the fixed grinding disc, so the fixed grinding disc (6) can generate the translation with the circular mass center locus by the rotation center line Z1 and the fixed eccentricity of the eccentric shaft (2). The balance flywheel (10) is fixed at the output end of the eccentric shaft (2), and the position of the mass center of the balance flywheel is opposite to the eccentric direction of the eccentric shaft (2). When the eccentric shaft (2) rotates, the balance flywheel (10) generates an eccentric rotating motion around a rotating center Z1 by a mass center M2 and is used for balancing the eccentric mass of a connecting part above the eccentric shaft (2). The damper (11) is used for reducing vibration generated when the disc type fixed eccentric grinding machine works. The supporting frame (12) is used for fixedly supporting the whole equipment.
