A discharge port is arranged at the lower right end of the tank body, the guide cover is connected to the discharge port, the bottom plate is installed at the lower inner wall of the tank body, and the right end of the bottom plate is communicated with the guide cover. Although the above document can improve the effect of the grinding machine on the crushing and grinding of waste tires, reduce the size of tire recycling particles, and improve the convenience of recycling; however, when in use, the crushing and grinding machine, in the process of crushing the waste tires, puts the waste tires into the machine for crushing and grinding. Due to the amount of waste tires put in each time, It is uneven. If a large amount of waste tires are placed, the fragments of the waste tires will accumulate above the two crushing rollers, which may result in incomplete crushing, thereby reducing the crushing effect of the crushing mill; at the same time, when the waste tires are ground into powder, the crushing mill will directly fall to the surface of the bottom plate and enter the conveyor belt for transportation out. Since there is no screening device inside the crushing mill to screen and separate the ground waste tires, the waste tire powder that does not meet the size cannot be screened out, thereby reducing the grinding quality of the crushing mill.
