In this embodiment, when the material enters the crushing box from the feed port 4 and is about to enter the crushing roller 8 area, the buffer assembly begins to function. The two first hydraulic buffers 13 support the first buffer plate 14 on the top, and the two second hydraulic buffers 15 on the other partition 12 also support the corresponding second buffer plate 16. The several guide shafts 17 rotatably connected on these buffer plates guide the material to approach the crushing roller 8 in a relatively gentle and uniform state, avoiding the problem of excessive impact force caused by the material directly hitting the crushing roller 8 due to gravity.
