These industries require regular shape, high packing density, high basic particle content (narrow particle size distribution), high-purity silicon carbide powder. According to the national standard of silicon carbide powder, this design focuses on the classification process design. According to the distribution characteristics of the original powder, from coarse to fine, three methods of screening, hydraulic overflow and air flow are selected to classify silicon carbide powder. Through theoretical calculation and equipment selection, the screening, hydraulic overflow and air flow processes are designed and arranged systematically. Based on this, the general layout of the plant, screening workshop, hydraulic overflow workshop and air flow classification workshop are drawn, and the hydraulic overflow equipment is designed in detail.<br>
