[0002] The graphite granulator can extrude graphite powder into graphite granules for primary granulation of the graphite powder to facilitate subsequent processing. The existing granulator generally has two granulating rollers, and the surfaces of the granulating rollers are provided with grooves. The grooves of the two granulating rollers correspond to each other to form a granulating space. A screw rod is arranged in the feed hopper. Through the rotation of the screw rod, the graphite powder is forcibly fed between the two granulating rollers. The two granulating rollers rotate reversely to extrude and form the graphite powder to complete granulation.

The machine shell 1 is fed through the feed hopper 101. The first granulating roller 2 and the second granulating roller 303 extrude the material into particles. The second hard brush 304 cleans the material and graphite particles adhering to the grooves of the granulating roller, avoiding material residue from affecting the granulation efficiency of the granulating roller. The machine shell 1 discharges the finished graphite particles into the sieving basket 407 through the discharge port 105. The electric cylinder 404 pushes the sliding frame 405 to slide back and forth on the top of the sliding table 403, so that the graphite particles collected in the sieving basket 407 are tumbled and sieved, and the unformed graphite debris falls into the dust collecting basket 406 for separation, facilitating the centralized collection of the formed graphite particles in the later stage. The sieving basket 407 is slidably connected to the strip-shaped chute two 1051 through the second directional pulley 4071, improving the smoothness and stability of the sieving basket 407 moving for sieving materials.
