[0044] Working principle: The box 1 is supported by support legs 2 fixed to its bottom. Workers can feed graphite electrodes into the intermediate crushing box 3 through the feed inlet 4. A pair of crushing rollers 5 inside the intermediate crushing box 3 perform intermediate crushing. The box 1 and the intermediate crushing box 3 are connected. The crushed graphite electrodes fall into the box 1. While the crushing rollers 5 crush the graphite electrodes, the cleaning rollers 6 on both sides, driven by the power unit, clean the crushing rollers 5, removing any adhering particles or dust. A first motor 9 is fixed to one side of the intermediate crushing box 3. When the first motor 9 drives the first rotating rod 7 to rotate, the pair of first rotating rods 7... The first gear 10, fixed at one end, meshes with each other, causing a pair of crushing rollers 5 to rotate, thus completing the crushing of the graphite electrode. The power unit can drive a pair of cleaning rollers 6 to clean the crushing rollers 5. By fixing a first sprocket 11 to a pair of first rotating rods 7 and a second sprocket 12 to a pair of second rotating rods 8, and connecting them through a pair of chains 13, when the first rotating rods 7 drive the crushing rollers 5 to rotate, the second rotating rods 8 drive the pair of cleaning rollers 6 to clean the crushing rollers 5, preventing graphite electrode particles or powder from adhering to the surface of the crushing rollers 5. By fixing a pair of support plates 14 inside the housing 1, and setting a screening plate 15 on the pair of support plates 14, the screening plate 15 can screen the crushed graphite electrode. The graphite electrode is used for sieving to separate particles of different sizes. When the operator starts the transmission mechanism, it drives the sliding plate 17, causing the sieving plate 15 to vibrate. This increases the sieving efficiency of the graphite electrode by the sieving plate 15. A second motor 18 is fixed to one side of the housing 1, and a third rotating rod 19 is set at the output end of the second motor 18. When the second motor 18 drives the third rotating rod 19 to rotate, the disc 20 rotates accordingly, causing a set of first protrusions 21 to contact the second protrusions 22 in sequence. This causes the sieving plate 15 to drive the sliding plate 17 to slide within the groove 16. Afterward, the spring rebounds, creating a vibration effect, which can accelerate the sieving efficiency of the graphite electrode by the sieving plate 15. To prevent graphite electrodes from getting stuck on the sieve plate 15 and causing blockage, a first groove 23 is opened on one side of the box 1, and a collection frame 24 is set in the groove to collect the graphite electrodes that fall from the sieve plate 15. The partition 25 divides the collection frame 24 into three parts. Electrodes that fail to pass through the sieve plate 15 will fall down from both sides of the sieve plate 15 into the collection frame 24, and the partition 25 is used to separate them. By fixing a pair of dust collectors 26 to the top of the box 1, the dust generated by the crushed graphite electrodes can be absorbed, keeping the intermediate crushing box 3 clean and reducing dust pollution. Rubber pads are set at the bottom of the support legs 2 to protect the support legs 2 and prevent friction with the ground.
