Inside the crushing cylinder 1, there is a guide seat 1011, and at the position corresponding to the pair of crushing rollers 101, there is a guide seat 1011. One end of the guide seat 1011 is fixed to the side wall of the crushing cylinder 1. The guide seat 1011 partially wraps around the outer periphery of the crushing rollers 101. The top of the pair of guide seats 1011 is a funnel-shaped inclined surface, which is used to guide the material between the pair of crushing rollers 101 for easy crushing.

[0023] The crushing cylinder base 1 is equipped with a rotating cylinder core 102 inside. The rotating cylinder core 102 is coaxial with the crushing cylinder base 1. One end of the rotating cylinder core 102 is rotatably connected to the crushing cylinder base 1.

The return strips 1021 are strip-shaped sheet metal with an "L" shaped cross section. An external gear 1023 is provided on the outer wall of the rotating cylinder core 102 near the end that is connected to the crushing cylinder base 1. A motor 103 is fixed on the side wall of the crushing cylinder base 1. The output shaft end of the motor 103 is provided with a drive gear 1031, and the drive gear 1031 is engaged with the external gear 1023. The motor 103 operates, causing the drive gear 1031 on the output shaft of the motor 103 to mesh with the external gear 1023 at one end of the rotating cylinder 102, thereby driving the rotating cylinder 102 to rotate. The return strip 1021 on the inner wall of the rotating cylinder 102 guides the material, lifts the material to the top of a pair of crushing rollers 101 for discharge, and then feeds the material back into the pair of crushing rollers 101 for crushing.
