Waste silicon carbide recycling system and method

The invention relates to a waste silicon carbide recycling system and method applied to the chemical field, through the arrangement of a lower scattering nozzle and other devices, silicon carbide in a material collecting groove is shoveled into a lifting disc in the rotating process of a shoveling pipe, and when the lifting disc rotates, the silicon carbide in the lifting disc is thrown to a grinding ring through the lower scattering nozzle, so that the silicon carbide can be recycled. By means of the arrangement, the silicon carbide can be sprayed on the surface of the grinding ring along the grinding track of the grinding roller, the grinding efficiency of the grinding roller is improved, the situation that only a small part of shoveled silicon carbide particles are ground by the grinding roller is avoided, the number of shoveling pipes is reduced, and the labor intensity of workers is reduced. Meanwhile, when silicon carbide particles sprayed from the lower material scattering nozzle contain silicon carbid
