The working principle is as follows: after the material W enters the feed hopper 9, the material W enters the crushing cavity 17 through the material baffle plate 10, under the driving of the driving motor 2, the driving shaft 15 drives the eccentric roller 21 to eccentrically rotate relative to the arc-shaped jaw plate 1201 of the jaw fixing device 12, so that the crushing cavity 17 between the eccentric roller and the jaw fixing device extrudes and crushes the material W in a periodically back-and-forth changing manner, and the crushed material W is discharged from the ore discharge opening 1701 and the discharge opening 18. Because the striker plate 10 is matched with the eccentric roller 16 through an elastic mechanism, the striker plate 10 can be ensured to be always tightly attached to the surface of the roller 16 despite the change of the surface position of the roller 16 of the eccentric roller 21. In order to compensate the abrasion of materials to the roller 16 and the arc-shaped jaw plate 1201, the hydraulic cylinder 13 of the adjusting device can drive the jaw fixing device 12 to move in parallel relative to the eccentric roller 21, the original sizes of the crushing cavity 19 and the ore discharge opening 1701 are kept, the angles a1 and a2 of the crushing jaws are not changed, the jaw fixing device 12 has the function of overloading and retracting when uncrushable materials pass through the crushing cavity 17, and the safety of the equipment can be protected. If the size of the crushed material W is to be changed, the jaw fixing device 12 can also be driven by the hydraulic cylinder 13 to move back and forth in parallel relative to the eccentric roller 21. After the surface of the roller 16 is abraded to a certain degree, the crushed material flows backwards towards the non-crushing cavity, the bottom plate 901 can be downwards adjusted through the bottom plate adjusting mechanism 8, so that the material baffle plate 10 is kept close to the roller surface, and the purpose of preventing the material from flowing backwards is achieved.
