[0038] The frame 100 is provided with two mounting frames 110 arranged opposite to each other, and a first material guide frame 120 and a second material guide frame 130 located between the two mounting frames 110. The two mounting frames 110, the first material guide frame 120 and the second material guide frame 130 together form a crushing chamber 140. A material drop opening 141 is provided at the bottom of the crushing chamber 140. Two ends of the crushing roller 200 are rotatably connected to the two mounting frames 110 respectively. The crushing roller 200 is located at the material drop opening 141. One side of the screen assembly 300 is rotatably connected to the second material guide frame 130. The screen assembly 300 is located between the two mounting frames 110 and below the crushing roller 200. The first fixed knife assembly 400 is arranged on the other side of the screen assembly 300.
