[0002] Silicon carbide materials are widely used in metallurgy, machinery, chemical industry, building materials and other industrial fields due to their excellent physical and chemical properties such as high temperature resistance, corrosion resistance, thermal stability and high hardness. They are also increasingly used in high-tech industries such as electronics and aerospace. In the process of silicon carbide production, there are differences in the outer diameter of silicon carbide particles, which will be graded.

[0003] After searching, the utility model patent with announcement number CN216368878U discloses a silicon carbide particle grading device, including a bottom plate, a tank body is arranged on the top of the bottom plate, a vibration mechanism is arranged inside the tank body, a filter screen is arranged inside the vibration mechanism, a dust removal mechanism is arranged on the top of the bottom plate, the vibration mechanism includes a motor, the right side of the tank body is fixedly connected with a motor with one end penetrating and extending into the interior, a rotating rod with one end movably connected to the left side of the inner wall of the tank body is fixedly installed on the output end of the motor, and four impact hammers are fixedly installed on the top and bottom of the rotating rod; the silicon carbide particle grading device has an anti-blocking function. When grading materials, the filter screen can be driven to vibrate on the top of the filter screen by continuously vibrating the filter screen, which not only avoids the situation that the material blocks the filter screen, but also increases the rate at which the material passes through the filter screen, thereby improving the efficiency of material grading.
