DEM is a method based on the theory of molecular dynamics that can simulate the movement of granular materials. Corn shelled was used as a test with continuous filling of 1000 ft3/hour for 20 seconds, while modeling by screw conveyor 2 meter long at positions 00, 200 and 450 with variations in speed of 50 rpm, 75 rpm and 100 rpm. The DEM simulation results at a speed of 100 rpm with inclination of 00 is 21,2 ton/hour and the required power of 1.58 HP. Different results are obtained in modeling with an inclination of 450, the capacity drops to 8,6 ton/hour with the required power of 11.8 HP. It can be seen that the capacity reduction due to inclination reaches more than 50% with a significant increase in power.
