A triangular slide 510 is connected to the bottom of any group of striking rollers 509, and a baffle 511 is fixedly installed on the top of one end of any group of triangular slides 510 away from the striking roller 509, so as to drive the striking roller 509 to repeatedly beat the graphite raw material at the top surface of the triangular slide 510, and the baffle 511 can prevent the graphite raw material on the top of the triangular slide 510 from sliding off.

[0034] like Figure 6As shown, as a preferred embodiment, on the basis of the above method, further, the stirring component 3 includes a mounting base 300, a motor 301 is fixedly provided on the top of the mounting base 300, the output end of the motor 301 is rotatably connected to the stirring shaft 302, the outer wall of the stirring shaft 302 is fixedly installed with evenly distributed stirring blades 303, and the end of the stirring shaft 302 away from the motor 301 is rotatably connected to the inner wall of the stirring tank body 2, so as to facilitate more thorough crushing of the graphite raw material and to evenly stir the small-particle graphite raw material.
