The input materials are crushed by the operation of the first crushing roller 305 and the second crushing roller 405. During the crushing process, if a larger material enters, a larger pressure will be applied to the second crushing roller 405, causing the spring 406 to contract. When the spring 406 contracts and deforms, the second crushing roller 405 can avoid to the other side to avoid being stuck with the material, and when the connecting seat 403 moves, it will move along the slide rail 401 through the connection of the slider 402, and play a supporting and limiting role for the movement of the connecting seat 403.

The hydraulic rods After 410 starts to extend, it can push the sliding rod 408 to move, thereby adjusting the distance between the second crushing roller 405 and the first crushing roller 305. While the crusher is running, the torque generated by the operation of the first rotating shaft 302 can be monitored in real time through the use of the torque tester 306. When the material is stuck, if the avoidance position of the second crushing roller 405 is insufficient, the torque data of the first rotating shaft 302 will be abnormal. When the abnormality occurs, the first motor 301 can be controlled to stop running through the torque tester 306, thereby achieving the purpose of protecting the crusher, avoiding the crusher from malfunction and damage caused by stuck materials, and prolonging the service life of the crusher. When the connecting seat 403 is pressed to move to avoid, when the connecting seat 403 moves to the maximum stroke, it will drive the trigger switch 407 to press against the inner wall of the body 1. At this time, after the trigger switch 407 is triggered, the second motor 4031 can be controlled to stop running, thereby avoiding the second crushing roller 405 from tooth damage.
