This article proposed an efficient design method for the vertical screw conveyor based on TCP-SHV. This method increases the throughput of the vertical screw conveyor by 20% for the same screw radius, the same pitch, and the same particle. The proposed method is greatly beneficial for the design of the vertical screw conveyor.
