Screw conveyors are widely used in granular transportation to provide an efficient and steady flow rate. DEM is a numerical method used to predict flow behaviors of granular material effectively. However, this method is computationally intensive. In this work, an artificial network model was trained using DEM simulation results to reduceA 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at Screw Conveyor Capacity Engineering Guide

This study conducted cold flow experimental research on the influence of mass flow rate on the atomization characteristics of screw conveyer swirl injectors in an opening environment. The Phase Doppler Particle Analyzer (PDPA) and high-speed photography were utilized to obtain experimental data. The results showed that the mass The transportation capacity in a screw conveyor is proportional to the screw rotating speed (Sander & Schönert, 1999). In this section, the filling ratio of particles in the screw conveyor was 20% and the screw rotating speed ranged from 300 to 1000 rpm. We first focused on the particle flow pattern in the screw conveyor.Numerical simulation of particle flow behavior in a screw conveyor
